It always surprises me to see radiant floor heat described as complicated or hard to do.
When you tied your lines into your wood boiler do you need a pump to push the water/coolant through the lines? Or is there enough pressure created from the wood heat to just naturally cycle the water/coolant? Very interested in this concept I'll be building a 25x40 quonset hut building and this is how I want to heat it.
@@moovin12 The water in the stove jacket, only about 20-30 gallons, is pumped thru a 60' loop of soft type K copper 1" tubing, that is immersed in the 200 gallon stainless tank. The floor water is supplied by the 200 gallon tank. That way, the stove can run "hot", hotter than I'd want to pump thru the floor. Do your homework on how to lay the tube/insulate the floor etc., and you can always play around with different, even multiple, ways to warm the water afterwards! Take it a step at a time in other words.
By far one of the best videos on DIY in-floor heat. As simple as it is, you drawing it on a piece of paper made it all come together for me. I do have a insulation question though, I have a 4 foot frost wall. Some advice I’ve gotten is to extend the side wall insulation all the way down to the footing. I’ve already backfilled and was planning on just going from grade to top of knee wall (it sticks up 1 foot above grade) and butt the floor insulation up against it. Your thoughts? I’m also a bit confused about the insulation at the garage doors. The walls drop down here, and the top of the wall is level with the rest of the dirt. Thanks for any tips!
@@bondobuilt386 Do these ever leak? If it leaks then you have to do what? Hammer out where you think it's leaking and then repair it? Can this radiant floor heat the entire living space alone or does it require another heat source in addition? Thanks!
Build a line spooler. You can do all of this work by yourself (one man team.) I made mine out of a couple scrap pieces of plywood with two ABS toilet flanges (adjustable ring) between them. One flange fits in the other to make your "Wheel". Use two 3/4" Black Malleable Iron Floor Flange Fittings and two 3/4" x 24" Black iron pipe nipples to hold the roll of Pex. Throw a 3rd piece of scrap plywood on top to hold it all down. Materials all available at HD or Lowes. Probably laid 300k feet of pipe in fifteen years with my 1st one. Retired it last fall and built a new one.
Hey Bondo, if my new house (barndominium) is on a monolithic slab, should the sides of the slab go below frost line, and how many inches thick should the main pad be? (3", 4", 6"???) I'm also reading about studies that find the Pex should be about 2" from the top of the slab, rather than at the bottom of the slab for optimal efficiency. If thats the case, I'm concerned about relief cuts made after the crete has dried, cutting the Pex. What are your thoughts? Lastly, I'm considering using 3" polystyrene sheets (R19) on the bottom and sides of the monolithic slab. Is 3" overkill, or should 2" be used?? I'm right near Syracuse, NY. I know your time is valuable- thanks for any input, and thanks for everything you do for the little guy, that has to do it for himself!!
Hi. The main pad should be 5-1/2 to 6" thick and the sides should be 12" thick. No need to go below the frost line. Protect the edge of slab with foam. The 3" foam would work great. Make sure it is closed cell polystyrene. Keep the tubing on the bottom and it will heat awesomely. I have done this about 100 times and in my own house as well. Works great.
Here is an idea that occurred to me after doing 4 of these systems: Rather than split the room into 4 quadrants for example, and run one loop through each, have each loop run through the entire room, spaced 5 feet apart. That way, heaven forbid one of the loops gets compromised even years down the road, you can still heat the entire room (not just 3/4 of it) with the remaining three working loops. I also discovered that "keeping the loops the same length " was not a "down-to-the-inch" requirement, and in cases where you cannot do this, you can employ a flow reduction valve (not exaclty like a shutoff valve, but similar) to introduce extra restance and balance the flow. When tying loops down to the mesh, I use zip ties, loose at first, so I can adjust things in case the layout is upset for some reason, loose ties are tightened as the plan resolves. I also close the system and air it up to a pressure of 20 PSI and have someone watch the gauge to discover if someone punctures a tube, but in fact, it has never happened thatone was punctured.
Thats a pretty good idea to space the tubing out like that in case of an issue down the road. Yes you are correct I think even 20 feet is close enough for tubing length I try and get it close so it balances itself. Shoirt cheap copper headers is all you need. We have never punctured a tube in over 100 radiant slabs. I used to tie tubing loose with ties also but now I do my backwards trick from the manifold when getting close to where I want to be. Thanks for the feedback I appreciate it. 👍😊
I’m building a new house with in floor heating like this only I want to connect it to a new wood burning green efficient stove to be off grid and want to connect it to in floor heating system. How can this be done?
@@bondobuilt386 a wood burning stove to heat my in floor heat and a wood burner to heat my hot water system for the entire house. I’m also doing the same thing in a new barn/apartment.
In this video , and this section , was that apartment section framed off, with interior partitions, my point is , I guess it is carefully measured , so the bottom plates anchors , do not hit , tubing, in one of your videos could you show this. - the drawing and explanation was fantastic great work ,, and thank you for taking your time out , to teach people , thank you so much , you are an asset to youtube,
Hi Ron, I love all of your videos. I try to be as practical as I can be, I think you do the same. I'm an old carpenter in Maine who had to retire for a few reasons. I want to install radiant heat in my house, no, not in concrete but under my floor. The Pex isn't that expensive, the heat source is and so are all of the other stuff to make it work "right". I like this approach to having one zone. I'm going to watch and re-watch your videos on radiant heating.
Incredibly helpful video, you got a new subscriber. I have a few questions I know you must be a busy man but I appreciate any that you can answer: 1. My project is going to have a concrete slab underneath it and/or possibly tile or linol (we're going over that stuff potentially with the concrete), I noticed you have some plastic sheets underneath your styrofoam, is that one of the requirements for sealing, or what exactly is it and why do you use it? Does it have to cover seamlessly or can it overlap? 2. The foam you use is just so you don't have to use as much concrete and to provide a half assed level surface to begin with I assume? Do I need the foam if I have a level surface already? 3. How do you do the pour side of things, do you use self levelling concrete? I'm wondering if I can do several pours layered on top of each other if necessary instead of just doing a big pour. 4. What's the minimum amount of concrete you need to have from top of pipe to floor (how big of a gap of concrete above pipe?
Hi. The plastic is a vapor barrier to stop the slab from wicking up moisture. Yes you can over lap it. The foam is necessary to keep the heat in and going up into structure instead of down Ito the ground below. The concrete should be a minimum of 4" and leave the tubing down on the foam board. The foam board should be closed cell polystyrene and 2" is best but you probably would be ok with 1-1/2" if hight is a problem.
Great video. I think I've watched all your videos. I do have a couple questions. I've heard the wire mesh doesn't do any good if it's not pulled up into the concrete. I've also seen guys using the staplers to attach the PEX to the insulation. Will the PEX still heat properly if it's at the bottom of the slab? Would it be better to use the mesh and pull it up as the concrete is being poured with the PEX attached? Just want to get the most efficiency out of the in-floor heat. Any thoughts? I'm planning on 4" concrete/4000# mix. Thanks for all you do for us first timers!
It works real good on the bottom of the concrete. Do NOT pull it it up or it will get damaged and you will get a leak in your system. I have never damaged a line or had a leak in 15 years of pouring radiant slabs.
Nicely done. Just a simple question if I may. Why would you not do the first run on the perimeter to have the higher heat near the edges? My mind says this would warm the perimeter best to make the rooms more comfortable. I have no experience with this heating but hope to someday have radiant heating in a house and garage in Kentucky or Tennessee. Thanks…
Thank you for a very informative video. It’s my first video watched about this system and I’m yet to learn more. What is the thickness of the poured concrete on the in floor heat?
Just found your channel. I’m doing my research on radiant floors. I want to do something similar. Living quarters next to a shop with heated floors throughout. My question is how do you do walls and a car lift on top of a heated floor? How thick is the slab? Do you worry about driving a nail and hitting a tube when anchoring the bottom plate of a wall? You can’t glue the bottom plate can you? I assume even though the floor is insulated you would still need treated lumber and that rolled out foam under the bottom plate? If so I don’t see how to avoid nails and the possibility of hitting a tube. I haven’t decided between a 4 post and a 2 post lift. A 4 post could just be set and not anchored. But a 2 post would need anchor bolts. Would you lay out your tubing and just avoid where you plan to have the lift? Thanks Mark
Hey Ron! New sub here. Thanks for the video, I'm staring down the wrong end of a big project and this helps a lot. Thanks again, and keep the great videos coming!
I keep watching your guy roll the tubing out and I’m thinking of a un-spooling cart for that task. Have you thought of this or is there already something built for that? I recently bought a custom reel for romex electrical cable, and it’s the first time over 30 years of doing electrical work that I can pull wire neatly by myself. Y’all are doing great though!
Ken the guy rolling the tubing is me. LOL They do make a un spooling reel for tubing but I think its easy with good help to just roll it out. We are fast at putting tubing down. Thanks for the comments 👍😊
@@bondobuilt386 Thank you for the quick response, as a DIY guy your explanations are valuable. I am familiar with that website so I will take look. I am interested in having in-floor heat in my build this upcoming summer and your videos have been great as I plan to lay the piping myself. Have you installed snow-melt mats underneath outside walkways? If so what is your experience with them?
New sub. I want to build my own garage / shop with an apartment upstairs. Its in the mtns of Colorado. The main house already has radiant heat and it’s amazing. Want to do the same and have a heated garage. Excited to watch your channel.
If a gal wanted to do radiant in-floor heating in her concrete basement, could I not lay down aluminum (like emergency blanket type stuff) and then run the tubing, and then more concrete on top? I've got the clearance. Ceiling height in my basement is 8'6"... Thoughts?
You could lay 1" to 1-1/2" closed cell foam on top of your floor then wire mesh and the tubing and then pour 3" of concrete on top. anything less then the 1" and it would loose a lot of heat to the old floor. If head room is good go with the 1-1/2" foam.
You're not worried about the fluid flowing threw the tubing on the metal rebar to rubbing a hole into the tubing? And are you using a general foam board to insulate the ground that you can get at any box store? Or is this a special foam board you had to order in?
Youn can get the foam from the big box stores. Just make sure it is Polystyreen. that is usually the green or blue board. You dont want to use Polyiso it is a open cell. Yopu want closed cell insulation. No worries with gthe tubing. It will be incased in concrete.
Is using 3/8 tubing out of the question? I want to install over existing floor and already have less than 8ft ceilings. I need to keep the increase in floor elevation as low as possible.
I never have tried using 3/8 tubing. So I can't advise it. The insulation will take up the most room so you could put thinner layer of closed cell spray foam down instead of the 2" board foam but don't skimp on insulation or it will cost a fortune to heat.
@@bondobuilt386 Without question I would use 1/2 in a new project, but I'm planning a retrofit over exist floor. I currently have only 89 inches...so. every 1/4 matters when it comes to my doors (walkout basement). I've seen 3/8 used for hot water lines because of increased velocity I just don't know how that would translate to radiant heat system. I only get one shot to get it right. My current strategy is to groove the floor with a $150 wall chaser if it goes reasonably fast or rent a walk behind if I can run more than one blades.
You want at least 1-1/2" of closed cell spray foam or 2" of expanded polystyrene. The blue board or pink board that you can buy at the box stores. You don't want open cell foam like polyiso as it will absorb m,oisture and not perform that well.
I was just wondering why you wouldn't pull the mesh up into the concrete? Doesn't it have to be in the middle of the concrete for strength? I am about to do a floor and would really like to know the reason not to. Also I see others do a pressure test on the tubing as they pour. Is that not neccessary? Is there different qualities of tubing what do you recommend? Really appreciate your videos. Thanks and hope you can find the time to help me out with information.
Curious, why didn't you use three 333ft loops to evenly use the 1000ft instead of having 200ft left on a roll? I really like these videos you put up. Thank you!
Glad you like tghe videos. 😊. Each section was 40X30 so it was 1200 feet of tubuing per section. In concrete you want 1 foot of tubing per square foot of concrete. The wire mesh is on a 6 inch grid so we run it everry other grid and its spaced at 1 foot. I’ll send you another video that explains it better. 👍
probably should have ran the first circuits on the perimeter and worked inwards. perimeter is always coldest. thats why my house bathroom is always cold, they didnt run in the perimeter first.
Counter flow layout gives most uniform heat on floor. Serpentine layout what you are using is uneven it's warmer on other end where water starts flowing hot into pipe. But does it matter on barn nope. But on residential house i would only use counter flow layout.
Hello sir. I’m a subscriber and have watched most of your videos. Enjoy them. Keep up the good work. Have few questions I’m putting radiant heat in my 2000 square foot home. 40x50 Do you recommend stapling the tubing to the foam insulation then placing grid mesh on top or another way? Also I’m thinking I will have 8 ins and outs for my loops in floor. Do you have recommendations for water heater and pump setup ? Thanks
Thank you for the great videos ... I like the straight-forward explanations. I'm working on building a 36x80 barndominium currently in western NY. I've seen so many different opinions and approaches to concrete thickness and mesh/rebar. I like that you are also in the NY region and trust that you build based on what has worked year after year. I notice you lay down the mesh before the tubing. Can you explain why you go that way ... is the mesh for strength or just to hold the tubing down? Also, I'm planning to go 4" thick with my concrete ... does that sound good to you, and if so, what PSI concrete would you use? My garage area will only have normal everyday vehicles in it.
Just wanted to wish and the Boyz a Merry Christmas and Happy New Year. I have an idea…. For New Year’s Eve… you and your crew make some of those famous rebar protectors.
there are some pex used for domestic water that are blue white and red. its nice to make cold white or blue and hot red. the pex for heating is usually red or orange. different manufactures but cheating needs an oxygen barrier in it.
Hi Michael. Yes you would be able to see them with a thermal image camera. Or just use bolts that are shorter than where the tubing is near the bottom.
THANKS Bondo!! Do you have a video on the simple header for this type of self balancing system and related water heater once it’s complete? We followed your Pex layout and it was easy. Now we’re ready to get it all connected and operational Thanks!!!
Would have been nice if you showed how you prepped the floor for the pex. You're right, running the pex is the easy part, but getting it ready for the pex is a little more involved than unrolling some pex.
I'm having a pole building built and I was talking to the contractor and said I wanted to do radiant flooring heat they told me I had to do it myself before the concrete pour layind the tubing myself my question is what would you do if you were planning on putting two or three car lifts in the building. It's a six inch pour.
Plan exactly where the lift posts will be and draw yourself a map of the locations. Make that area about 12" thick and around 2.5' X 2.5' square. Do not put the tubing in those squares. Take a video also of the locations or pictures with measurements. Then instal lifts after the concrete has cured for 3 weeks to a month.
Definitely a good video. We're working with a company in Vermont and they want me to use 7/8 pex instead of a smaller size and use 16-18 inch centers. What are your thoughts on these specs? We're using an outside wood boiler to heat the water. We're in TN.
If it was me I would just run the 1/2" oxygen barrier pipe on 1 foot centers and keep the runs around the same length. No longer than 500foot loops and it will work awesome but make sure to use 2" of closed cell polystyrene foam under the concrete.
How did you fasten the foam board to the edges? it looks like you may have used a screw with a large washer? or was it a specific fastener? Looking at doing this same set up in my project. Great video! Thank you!
AMAZING video, thanks for sharing!! So just to clarify, if you have 1 foot spacing, you will use 1 foot of tubing per sq foot? And is there concerns about longevity of this system to leaks or other failures? It seems like there's no repair once the concrete is poured.
I am doing a 32'x46' garage, I am assuming you are using 1/2" pex? Also based on your experience, what type of wall mounted boiler have you had the best results with? Or water heater? Thank you.
I recommend radiant heat there yes. In my opinion if your feet are warm you will feel so much more comfortable. Whenever I go into a house now I can immediately feel there cold floors. LOL
Couldn't help but notice that the columns in your walls are treated up to a certain height to protect from rot etc.. My question is this: how are those columns stitched together so smoothly, or is it painted on to that height?
You can buy poles that are made like that. They splice treated wood to the regular wood. I believe its all glued together and then sent through a planer. They are straighter then a treated 6X6.
If I was 60 ft shorter on my last of 5 runs. Can you just run the extra tubing closer together on the last turn or two to keep loops closer In length and a balanced system? Or would it cause some sort of problem besides the spot being a little warmer than rest of the floor.
@@bondobuilt386 thank you much I liked and subscribed . I was just.curious to see if you could do that if someone had already messed up the lengths. Figured it might be a good question that others might need an answer for. good content on your channel and considering doing small system in my garage but powering with an off grid solar array. So I still got some learning to do before I dive in but this makes the inflow heating part much more simple thank you again. I did block and concrete in stone work for a few years it's really hard work you guys make it look easy to easy!!
@@prolifictroll9387 Thanks. The nice thing is just get the insulation and tubing in there and figure out the system later. Only 1 shot to do the in concrete stuff LOL
I thought the loops had to be under 300'. That's why they sell 300' rolls. I was also told you didn't want more than 30 degree temperature swing between output water temp and return temp. Maybe you're in a warmer climate then me.
I can get the tubing in 1000’ rolls. Once a slab is up to temp it looses verry little temp in 500’. This is of course that the building and the slab are insulated properly. The 300’ rule was brought on when they were hooking up radiant to old cast iron boilers with low head pressure pumps. The cast iron boilers dont like dumping colder return water back in them. We mostly heat with 50 gallon commercial duty water heaters or modulating boilers or wood boilers. They are designed to take colder return temp water. Also the pumps are just a stronger pump to overcome more head pressure from a longer run. The entire process is simplified with the longer runs of tubing at the same length. The headers are short and simple. We have done 100’s of these and I live in upsrtate New York and its a cold climate. Thanks for the questions 👍
Rhaulman A modern condensing boiler benefits from cooler return temperatures! In Europe where condensing boilers are mandatory, systems are designed to return water as cool as possible. They are a perfect match for UFH as they operate in condensing mode at all times, which is not always the case with hotter running radiator systems.
I push water through 6x 250' loops with a single 1/25th HP pump with the 3-way switch set at its lowest setting. Works fine. No issue, 20+ years in place, and here in New Brunswick Canada, it would not qualify as a warmer climate, we run our outdoor wood boiler from before Hallowe'en until mid-May or later.
I did my 30x56 post frame home by myself. Did three zones 2 bedrooms and main living room and kitchen. 8" of compacted gravel base first then Vapor Barrier with 2" foam board taped seems on top then steel mesh . Put the plastic towers to raise the mesh. Zip ties for the oxygen Barrier tubing. Foam around edges. I run it with one instant water heater. It's the best heat I've ever seen in my life you can't get more comfortable heat. Going on two year's of comfortable bliss lol.

Hey Bondo, if my new house (barndominium) is on a monolithic slab, should the sides of the slab go below frost line, and how many inches thick should the main pad be? (3", 4", 6"???)
I'm also reading about studies that find the Pex should be about 2" from the top of the slab, rather than at the bottom of the slab for optimal efficiency. If thats the case, I'm concerned about relief cuts made after the crete has dried, cutting the Pex. What are your thoughts?
Lastly, I'm considering using 3" polystyrene sheets (R19) on the bottom and sides of the monolithic slab. Is 3" overkill, or should 2" be used?? I'm right near Syracuse, NY.
I know your time is valuable- thanks for any input, and thanks for everything you do for the little guy, that has to do it for himself!!
Hi. The main pad should be 5-1/2 to 6" thick and the sides should be 12" thick. No need to go below the frost line. Protect the edge of slab with foam. The 3" foam would work great. Make sure it is closed cell polystyrene. Keep the tubing on the bottom and it will heat awesomely. I have done this about 100 times and in my own house as well. Works great.
@@bondobuilt386 Thank you for your help!! I truly appreciate your time!!
Here is an idea that occurred to me after doing 4 of these systems: Rather than split the room into 4 quadrants for example, and run one loop through each, have each loop run through the entire room, spaced 5 feet apart. That way, heaven forbid one of the loops gets compromised even years down the road, you can still heat the entire room (not just 3/4 of it) with the remaining three working loops.
I also discovered that "keeping the loops the same length " was not a "down-to-the-inch" requirement, and in cases where you cannot do this, you can employ a flow reduction valve (not exaclty like a shutoff valve, but similar) to introduce extra restance and balance the flow.
When tying loops down to the mesh, I use zip ties, loose at first, so I can adjust things in case the layout is upset for some reason, loose ties are tightened as the plan resolves.
I also close the system and air it up to a pressure of 20 PSI and have someone watch the gauge to discover if someone punctures a tube, but in fact, it has never happened thatone was punctured.
Thats a pretty good idea to space the tubing out like that in case of an issue down the road. Yes you are correct I think even 20 feet is close enough for tubing length I try and get it close so it balances itself. Shoirt cheap copper headers is all you need. We have never punctured a tube in over 100 radiant slabs. I used to tie tubing loose with ties also but now I do my backwards trick from the manifold when getting close to where I want to be. Thanks for the feedback I appreciate it. 👍😊
@@bondobuilt386 You are welcome.
Is the 400ft due to the ability of the circulation pump? So if you run 3 400ft loops you gotta have 3 circulation pumps?
@@papabear6092 naw, one pump is fine. I have three zones with one pump on each pushing through 5 and 6 "loops" of 250' each.
Thanks Bondo best explanation and video I’ve seen
Jeffrey I’m glad you liked the video bud. Radiant heat is awesome thing to have in a house or shop. 👍👍
I’m building a new house with in floor heating like this only I want to connect it to a new wood burning green efficient stove to be off grid and want to connect it to in floor heating system. How can this be done?
Do you want to use a boiler? or just a wood stove?
@@bondobuilt386 a wood burning stove to heat my in floor heat and a wood burner to heat my hot water system for the entire house. I’m also doing the same thing in a new barn/apartment.
You should fill it with kryotech which is like a antifreeze but it's made for heating boilers
Great example and explanation, keep up the good work.👍
In this video , and this section , was that apartment section framed off, with interior partitions, my point is , I guess it is carefully measured , so the bottom plates anchors , do not hit , tubing, in one of your videos could you show this. - the drawing and explanation was fantastic great work ,, and thank you for taking your time out , to teach people , thank you so much , you are an asset to youtube,
I would really like to see a radiant system after completion (the heater, valves & manifolds)
John. I will see if i can get that for you guys this fall. 👍
ruclips.net/video/LidclAf2ODo/видео.html John here is my boiler set up as promised. 😊👍
I saw a video with wire over tubing. This seems much better.
Not sure how they tied the tubing up. Could do 2 mats one over one under?
Hi Ron, I love all of your videos. I try to be as practical as I can be, I think you do the same. I'm an old carpenter in Maine who had to retire for a few reasons. I want to install radiant heat in my house, no, not in concrete but under my floor. The Pex isn't that expensive, the heat source is and so are all of the other stuff to make it work "right". I like this approach to having one zone.
I'm going to watch and re-watch your videos on radiant heating.
ruclips.net/video/wWWfFER9Spw/видео.html Hi Roy thanks for the comments This new video should be helpful to ya.
great job ron
Thanks
Laying the pex is easy. setting up the boiler is the head scratcher
Incredibly helpful video, you got a new subscriber. I have a few questions I know you must be a busy man but I appreciate any that you can answer:
1. My project is going to have a concrete slab underneath it and/or possibly tile or linol (we're going over that stuff potentially with the concrete), I noticed you have some plastic sheets underneath your styrofoam, is that one of the requirements for sealing, or what exactly is it and why do you use it? Does it have to cover seamlessly or can it overlap?
2. The foam you use is just so you don't have to use as much concrete and to provide a half assed level surface to begin with I assume? Do I need the foam if I have a level surface already?
3. How do you do the pour side of things, do you use self levelling concrete? I'm wondering if I can do several pours layered on top of each other if necessary instead of just doing a big pour.
4. What's the minimum amount of concrete you need to have from top of pipe to floor (how big of a gap of concrete above pipe?
Hi. The plastic is a vapor barrier to stop the slab from wicking up moisture. Yes you can over lap it. The foam is necessary to keep the heat in and going up into structure instead of down Ito the ground below. The concrete should be a minimum of 4" and leave the tubing down on the foam board. The foam board should be closed cell polystyrene and 2" is best but you probably would be ok with 1-1/2" if hight is a problem.
Great video. I think I've watched all your videos. I do have a couple questions. I've heard the wire mesh doesn't do any good if it's not pulled up into the concrete. I've also seen guys using the staplers to attach the PEX to the insulation. Will the PEX still heat properly if it's at the bottom of the slab? Would it be better to use the mesh and pull it up as the concrete is being poured with the PEX attached? Just want to get the most efficiency out of the in-floor heat. Any thoughts? I'm planning on 4" concrete/4000# mix. Thanks for all you do for us first timers!
It works real good on the bottom of the concrete. Do NOT pull it it up or it will get damaged and you will get a leak in your system. I have never damaged a line or had a leak in 15 years of pouring radiant slabs.
Damn good explanation in executing. Made it simple to understand. Thanks
Awesome 😎
Best video on pex ever
Killer Video scoped out some others u have done 👍👍👍 also I subscribed keep up Excellent work 👍👍👍
Thanks Brad I'm glad you like the videos and subscribed. I appreciate that bud.
Grateful for this presentation!
awesome glad it helped ya.
Awesome!!!!!!!!!!!! I Don't need to put stone down first?? I can go right on compacted soil?
Can you review different systems like Uponor?
Nicely done. Just a simple question if I may. Why would you not do the first run on the perimeter to have the higher heat near the edges? My mind says this would warm the perimeter best to make the rooms more comfortable. I have no experience with this heating but hope to someday have radiant heating in a house and garage in Kentucky or Tennessee. Thanks…
I like to keep the heat in the concrete it will try and escape to the cold if put by the edges.
@@bondobuilt386 thanks. Sounds reasonable.
@@dang6832 No problem 👍
Bondo is there a video that follows this one up and teaches us everything we need to know to hook it up to a water heater
The diagram was big help. Thanks
Dude these are great videos. I like the Nick names Karl with a "k" and big biscuit.
Thanks Tyler. I try and make them educational but also fun to make and watch. Appreciate the comment bud. 👍😊
Thank you for a very informative video. It’s my first video watched about this system and I’m yet to learn more. What is the thickness of the poured concrete on the in floor heat?
5-1/2" thick thanks.
Just found your channel. I’m doing my research on radiant floors.
I want to do something similar. Living quarters next to a shop with heated floors throughout. My question is how do you do walls and a car lift on top of a heated floor?
How thick is the slab? Do you worry about driving a nail and hitting a tube when anchoring the bottom plate of a wall? You can’t glue the bottom plate can you? I assume even though the floor is insulated you would still need treated lumber and that rolled out foam under the bottom plate? If so I don’t see how to avoid nails and the possibility of hitting a tube.
I haven’t decided between a 4 post and a 2 post lift. A 4 post could just be set and not anchored. But a 2 post would need anchor bolts. Would you lay out your tubing and just avoid where you plan to have the lift?
Thanks
Mark
What about antifreeze? Obviously this seems to be the best and cheapest way to do this Ive seen! Nice work
Is the wire mesh basically just for affixing the tubing at this point? With fiber additive, you don't need it for concrete strength, right?
That is true Shawn. If you wanted more reinforcement put some over the tubing bud. 😊
Excellent teaching! Thanks!
Thanks awesome I could help. 👍
can you have a splice in the middle of the system?
Mat you can but I try and avoid splices under the concrete I use up partial rolls for domestic water runs or heat runs in the floor joist. 😊
Great video ! I think a 1200 sq ft apartment would be enough for me lol !
Thanks Glenn

@@gabedodson6378 you bet. 👍
I keep watching your guy roll the tubing out and I’m thinking of a un-spooling cart for that task. Have you thought of this or is there already something built for that? I recently bought a custom reel for romex electrical cable, and it’s the first time over 30 years of doing electrical work that I can pull wire neatly by myself. Y’all are doing great though!
Ken the guy rolling the tubing is me. LOL They do make a un spooling reel for tubing but I think its easy with good help to just roll it out. We are fast at putting tubing down. Thanks for the comments 👍😊
Where do you get your supplies?
it's called Supply House online.
@@bondobuilt386 Thank you for the quick response, as a DIY guy your explanations are valuable. I am familiar with that website so I will take look. I am interested in having in-floor heat in my build this upcoming summer and your videos have been great as I plan to lay the piping myself. Have you installed snow-melt mats underneath outside walkways? If so what is your experience with them?
I am curious why you wouldn’t run 4 - 300 ft loops to avoid the 200 ft of waste off the 1000 ft role? What is the optimal cover?
New sub. I want to build my own garage / shop with an apartment upstairs. Its in the mtns of Colorado. The main house already has radiant heat and it’s amazing. Want to do the same and have a heated garage. Excited to watch your channel.
Thanks for subscribing Michael.Sounds like a sweet project bud. Hit me up if you have any questions. 👍😊
If a gal wanted to do radiant in-floor heating in her concrete basement, could I not lay down aluminum (like emergency blanket type stuff) and then run the tubing, and then more concrete on top? I've got the clearance. Ceiling height in my basement is 8'6"... Thoughts?
You could lay 1" to 1-1/2" closed cell foam on top of your floor then wire mesh and the tubing and then pour 3" of concrete on top. anything less then the 1" and it would loose a lot of heat to the old floor. If head room is good go with the 1-1/2" foam.
What supplies the water through the tubing? This seems like something that an outdoor wood boiler would be able to heat.
You're not worried about the fluid flowing threw the tubing on the metal rebar to rubbing a hole into the tubing? And are you using a general foam board to insulate the ground that you can get at any box store? Or is this a special foam board you had to order in?
Youn can get the foam from the big box stores. Just make sure it is Polystyreen. that is usually the green or blue board. You dont want to use Polyiso it is a open cell. Yopu want closed cell insulation. No worries with gthe tubing. It will be incased in concrete.
@@bondobuilt386 I have a few more questions for you to pick at your brain. Do you have an email that I can send my questions to you?
Is using 3/8 tubing out of the question? I want to install over existing floor and already have less than 8ft ceilings. I need to keep the increase in floor elevation as low as possible.
I never have tried using 3/8 tubing. So I can't advise it. The insulation will take up the most room so you could put thinner layer of closed cell spray foam down instead of the 2" board foam but don't skimp on insulation or it will cost a fortune to heat.
@@bondobuilt386 Without question I would use 1/2 in a new project, but I'm planning a retrofit over exist floor. I currently have only 89 inches...so. every 1/4 matters when it comes to my doors (walkout basement). I've seen 3/8 used for hot water lines because of increased velocity I just don't know how that would translate to radiant heat system. I only get one shot to get it right. My current strategy is to groove the floor with a $150 wall chaser if it goes reasonably fast or rent a walk behind if I can run more than one blades.
What insolation do you recommend?
You want at least 1-1/2" of closed cell spray foam or 2" of expanded polystyrene. The blue board or pink board that you can buy at the box stores. You don't want open cell foam like polyiso as it will absorb m,oisture and not perform that well.
Awesome video ! ! Very informative & looks easy to do yourself after watching ! 👍👌
Thanks Bob glad I could help ya buddy. 👍😊
I was just wondering why you wouldn't pull the mesh up into the concrete?
Doesn't it have to be in the middle of the concrete for strength?
I am about to do a floor and would really like to know the reason not to.
Also I see others do a pressure test on the tubing as they pour. Is that not neccessary?
Is there different qualities of tubing what do you recommend?
Really appreciate your videos. Thanks and hope you can find the time to help me out with information.
Curious, why didn't you use three 333ft loops to evenly use the 1000ft instead of having 200ft left on a roll? I really like these videos you put up. Thank you!
Glad you like tghe videos. 😊. Each section was 40X30 so it was 1200 feet of tubuing per section. In concrete you want 1 foot of tubing per square foot of concrete. The wire mesh is on a 6 inch grid so we run it everry other grid and its spaced at 1 foot. I’ll send you another video that explains it better. 👍
ruclips.net/video/MgAJmah0anM/видео.html
I live in Ca and always see the concrete poured directly on compacted soil, is that foam board under the wire mesh and why is it used? ty.
It's 2" closed cell foam and it is there to make the heated concrete not loose heat to the ground.
do you need a frost footer if the floor is heated?
Whats the point of the wire mesh under the poly? Wont it essentially be below the concrete instead of in it?
Hey , do you like the mesh wire plastic chairs. To raise the wire and tubing up a little.?
.
Thanks Man. Hope people get my Joke about the 6’ ladder. 😊
probably should have ran the first circuits on the perimeter and worked inwards. perimeter is always coldest. thats why my house bathroom is always cold, they didnt run in the perimeter first.
Sounds like they may have skimped on insulation as well.
@@bondobuilt386 I’m not sure. My house has 1” xps but I would probably go to 2” to get the R12 equivalent.
Counter flow layout gives most uniform heat on floor. Serpentine layout what you are using is uneven it's warmer on other end where water starts flowing hot into pipe. But does it matter on barn nope. But on residential house i would only use counter flow layout.
I’m going to do a 20x20 cabin
Should I do one loop or do 2?
You could do it with one but I would do 2. Easy layout and tiny little brass header.
Do you test for leaks before you cement over it?
No I have never had a leak in like 100 pours. 👍
After you set grade for the foam board did you have to compact the dirt/sand?
Hello sir. I’m a subscriber and have watched most of your videos. Enjoy them. Keep up the good work.
Have few questions
I’m putting radiant heat in my 2000 square foot home. 40x50
Do you recommend stapling the tubing to the foam insulation then placing grid mesh on top or another way?
Also I’m thinking I will have 8 ins and outs for my loops in floor. Do you have recommendations for water heater and pump setup ?
Thanks
I'm astonished how thin the floor insulation is compared to UK building requirements.
What do you use to heat the water? Can you simply use a hot water heater? Is there any reason that wouldn’t work?
You can use a gas water heater or any type of boiler.
Thank you for the great videos ... I like the straight-forward explanations. I'm working on building a 36x80 barndominium currently in western NY. I've seen so many different opinions and approaches to concrete thickness and mesh/rebar. I like that you are also in the NY region and trust that you build based on what has worked year after year. I notice you lay down the mesh before the tubing. Can you explain why you go that way ... is the mesh for strength or just to hold the tubing down? Also, I'm planning to go 4" thick with my concrete ... does that sound good to you, and if so, what PSI concrete would you use? My garage area will only have normal everyday vehicles in it.
4” is light I’d do 5.5” just using 2x6 forms
Just wanted to wish and the Boyz a Merry Christmas and Happy New Year. I have an idea…. For New Year’s Eve… you and your crew make some of those famous rebar protectors.
How do you calculate what lengths of tubing for the square foot of flooring.
Thank you so much for sharing your knowledge. It has been a godsend especially through covid and has helped provide me with motivation!!!
Awesome I’m so glad my videos are helpful to you guys. Your very welcome buddy. And yes this COVID needs to go away. 👍
Are the tube colors code for something? I have seen red, blue, orange and white tubing - do the different colors signify anything?
there are some pex used for domestic water that are blue white and red. its nice to make cold white or blue and hot red. the pex for heating is usually red or orange. different manufactures but cheating needs an oxygen barrier in it.
How would you bolt things to the floor? Would the pipes show well enough with a thermal gun with the heat on?
Hi Michael. Yes you would be able to see them with a thermal image camera. Or just use bolts that are shorter than where the tubing is near the bottom.
How do you keep from punctuating the line when putting in your walls?
Use PL Premium glue on bottom plate and tap cons that only go in floor 1-1/2" Markmyour drill bit so you don not over drill to deep.
THANKS Bondo!! Do you have a video on the simple header for this type of self balancing system and related water heater once it’s complete?
We followed your Pex layout and it was easy. Now we’re ready to get it all connected and operational Thanks!!!
ruclips.net/video/LidclAf2ODo/видео.htmlsi=0SOVLU0sUKn7tlFa
Glad the tubing video helped ya.
Would have been nice if you showed how you prepped the floor for the pex. You're right, running the pex is the easy part, but getting it ready for the pex is a little more involved than unrolling some pex.
ruclips.net/video/JcBpTpNxneI/видео.html here is the prep video. Should be very helpful
couple questions. the wire mesh sits right on the insulation? Also how do you do relief cuts in the slab ?
I'm having a pole building built and I was talking to the contractor and said I wanted to do radiant flooring heat they told me I had to do it myself before the concrete pour layind the tubing myself my question is what would you do if you were planning on putting two or three car lifts in the building. It's a six inch pour.
Plan exactly where the lift posts will be and draw yourself a map of the locations. Make that area about 12" thick and around 2.5' X 2.5' square. Do not put the tubing in those squares. Take a video also of the locations or pictures with measurements. Then instal lifts after the concrete has cured for 3 weeks to a month.
Definitely a good video. We're working with a company in Vermont and they want me to use 7/8 pex instead of a smaller size and use 16-18 inch centers. What are your thoughts on these specs? We're using an outside wood boiler to heat the water. We're in TN.
If it was me I would just run the 1/2" oxygen barrier pipe on 1 foot centers and keep the runs around the same length. No longer than 500foot loops and it will work awesome but make sure to use 2" of closed cell polystyrene foam under the concrete.
How do you anchor your walls in the apartment end without puncturing your radiant pex ?
How did you fasten the foam board to the edges? it looks like you may have used a screw with a large washer? or was it a specific fastener? Looking at doing this same set up in my project.
Great video! Thank you!
Thank u so much I'm doing a 80 x60 shop great work my friend
AMAZING video, thanks for sharing!! So just to clarify, if you have 1 foot spacing, you will use 1 foot of tubing per sq foot? And is there concerns about longevity of this system to leaks or other failures? It seems like there's no repair once the concrete is poured.
What pump and water heater do you recommend?
The walls are in my pole barn. I would like to run the foam down below 2 feet. Do you have a video showing how that was done?
No sorry we don’t run the foam down deep like that. Its just the thickness of the slab around the edges and under the slab 2” of polystyreen.
I am doing a 32'x46' garage, I am assuming you are using 1/2" pex? Also based on your experience, what type of wall mounted boiler have you had the best results with? Or water heater? Thank you.
Yes 1/2" oxygen barrier pipe. I would use a gas water heater. HTP Phoenix light duty is a good one for the price.
This looks good. Now, show us the pump setup.
do you recommend radiant heat in central florida on a marble floor covering?
I recommend radiant heat there yes. In my opinion if your feet are warm you will feel so much more comfortable. Whenever I go into a house now I can immediately feel there cold floors. LOL
What kind of temperature prob do you bury in to the concrete, or do you just use a wall thermostate for temperature control of the area?
Couldn't help but notice that the columns in your walls are treated up to a certain height to protect from rot etc.. My question is this: how are those columns stitched together so smoothly, or is it painted on to that height?
You can buy poles that are made like that. They splice treated wood to the regular wood. I believe its all glued together and then sent through a planer. They are straighter then a treated 6X6.
Great video
Thanks. 😀
What size is the PEX? Is 1/2" sufficient?
Yes 1/2" oxygen barrier tubing.
If I was 60 ft shorter on my last of 5 runs. Can you just run the extra tubing closer together on the last turn or two to keep loops closer In length and a balanced system? Or would it cause some sort of problem besides the spot being a little warmer than rest of the floor.
We have done that with no problem at all. I would rather have loops the same length than worry about a little hotter spot. You will never know it
@@bondobuilt386 thank you much I liked and subscribed . I was just.curious to see if you could do that if someone had already messed up the lengths. Figured it might be a good question that others might need an answer for. good content on your channel and considering doing small system in my garage but powering with an off grid solar array. So I still got some learning to do before I dive in but this makes the inflow heating part much more simple thank you again. I did block and concrete in stone work for a few years it's really hard work you guys make it look easy to easy!!
@@prolifictroll9387 Thanks. The nice thing is just get the insulation and tubing in there and figure out the system later. Only 1 shot to do the in concrete stuff LOL
I thought the loops had to be under 300'. That's why they sell 300' rolls. I was also told you didn't want more than 30 degree temperature swing between output water temp and return temp. Maybe you're in a warmer climate then me.
I can get the tubing in 1000’ rolls. Once a slab is up to temp it looses verry little temp in 500’. This is of course that the building and the slab are insulated properly. The 300’ rule was brought on when they were hooking up radiant to old cast iron boilers with low head pressure pumps. The cast iron boilers dont like dumping colder return water back in them. We mostly heat with 50 gallon commercial duty water heaters or modulating boilers or wood boilers. They are designed to take colder return temp water. Also the pumps are just a stronger pump to overcome more head pressure from a longer run. The entire process is simplified with the longer runs of tubing at the same length. The headers are short and simple. We have done 100’s of these and I live in upsrtate New York and its a cold climate.
Thanks for the questions 👍
Rhaulman A modern condensing boiler benefits from cooler return temperatures! In Europe where condensing boilers are mandatory, systems are designed to return water as cool as possible. They are a perfect match for UFH as they operate in condensing mode at all times, which is not always the case with hotter running radiator systems.
@@spencerwilton5831 I agree completely with that statement buddy. 👍
I push water through 6x 250' loops with a single 1/25th HP pump with the 3-way switch set at its lowest setting. Works fine. No issue, 20+ years in place, and here in New Brunswick Canada, it would not qualify as a warmer climate, we run our outdoor wood boiler from before Hallowe'en until mid-May or later.
@@Wingnut_Stickman nice it’s cold where I live too. Love the wood boilers I got a couple videos on mine and one we built for my buddy. 👍🤜
Would you consider a comparison of hydronic radiant slab ( liquid in tubes ) vs heated/cooled air radiant slab ( heat/cooled air in tubes )?
Stephen I have never even heard of running heated or cooled air through tubes in concrete buddy.
