Richard installed the High Intensity Radiant Workshop Heater, manufactured by Mr. Heater [www.mrheater.com/].
Time: 3-4 hours
Cost: $500
Skill Level: Expert
Tools List for Heating a Garage Workshop:
Drill driver
Pipe cutters
Shopping List:
Radiant Workshop Heater
Lag bolts
Washers for bolts
Spade bit
Drywall screws
Flexible gas line
Gas pipe fittings
Gas pipe in various sizes
Pipe dope
Vent
Thermostat
Steps:
1. Working with gas is extremely dangerous and should only be left to a licensed professional.
2. Shut the gas off at the meter.
3. Determine a location to mount the heater that’s easily accessible to the gas line. To give the heater more range, try mounting it in a corner.
4. Mount the bracket for the heater to the chosen location using bolts and a drill. Be sure to follow the instructions to ensure proper clearance from the walls and ceiling.
5. Slide the heater onto the mounting bracket and secure it with nuts that come with the heater.
6. Drill a hole into the wall or ceiling using the drill with a spade bit to connect the gas piping.
7. Screw the mounting bracket provided with the heater into the wall or ceiling using the drill and some drywall screws.
8. Connect the flexible gas line to the existing gas line and then pass it through the bracket.
9. Thread the fitting and brass connection that come with the heater onto the flexible gas line and then screw the fitting onto the bracket.
10. Connect the flexible gas line to the heater using a variety of gas pipe, fittings, elbows, and nipples. Use pipe dope to secure all the connections.
11. Drill a hole on the other end of the garage and install a vent to ensure there is another air flow to allow exhaust to escape the room.
12. Connect the thermostat to the heater and attach it to the wall.
13. Turn the gas back on.
Resources:
The other materials Richard used to install the heater, including the gas piping, the flexible gas line, and the plywood to hold the bracket for the heater, can all be found at home centers.

@2:40 - the official motion of "that baby isn't going anywhere."
He stripped the bolt...
I think the lag bolt threads were still in tact, but he stripped the wood or drywall out because he missed the stud. Not sure why you would have used a bolt that large and a torque gun anyway. That's asking for trouble.
I've installed and serviced Radiant and unit heaters, as a commercial HVAC technician. On Radiant heaters, though more efficient on the gas use. I prefer a Hanging unit heater. The fan/ Heat exchanger will not get clogged as mentioned, not going to happen, ever. Dust will accumulate on the heat exchanger surface that's about it. blow it off in the fall and turn that sucker on and enjoy. Working under and around radiant heaters in a garage setting with high ceilings.. those guys suffer with the bays even slightly open.
We installed a Mitsubishi Mini-split in our garage several years ago, air conditioned and dehumidifier and , wow, a heater. Low humidity in the heat of summer in Florida. Operating costs at a minimum. Be sure to insulate the door and ceiling. I give it a three thumbs up. 👍👍👍. 12-19-21
I ran a gas line, 2 electrical circuits and installed a gas furnace and central air conditioner in my garage 15 years ago. a little pricey but never regretted it. makes working out there enjoyable.
you can also do a heat pump for the garage and just tape a pre-filter with filter material roll on the exterior of the intake vent
I was in a mechanic’s 4 car shop today. It had heated floors. It is the best heat ever. Even and nice heat.
Heated floors, wow. I have not heard this since I was about 10 years old living at home with my parents and my dad installed water heated pipes in the basement in Illinois, Chicago area. That was 68 years ago. The absolute best heat and it never caught on, never. As I said, wow.
Woodstove for me. Have place to heat a pot of coffee. A lot less expense than gas, propane, or electric. Also gives a place to burn up unwanted scrap. But then again I have a lot of scrap from remodeling and framing jobs. I don't know, just a better heat in my opinion.
Hopefully you live in the middle of the woods otherwise your neighbors are breathing smoke
When you own a forest, wood is free!
In the midwest (missouri) natural gas is supplied to residential properties at high pressure. The gas goes through the meter and then is regulated down to just 3-4#'s of pressure. If there is any distance between the separate garage and home, there will not be enough pressure to fire that heater or a furnace. Check your local gas supplier.
Very nice it's great to see you guys are in Ohio because we are in Cleveland Ohio. Thanks for making another great video
2 degrees Celsius in the winter for where I live is a nice warm spring day! Winters in Cobden, Ontario, Canada get down to -40 C easily, that heater is not nearly enough!
I use a blue flame heater in my garage. Wall hung, self contained unit. No power needed, and have used it in the winter during a power outage. Natural gas appliances will process the air, so if you stain/paint anything, the smell does get amplified. I don't work with gasoline in the garage, so I'm fine with an open flame.
we use an industrial size propane burner for our garage workshop and a small woodstove.
Double tap everything to make sure it’s all solid
Issac Charlton hehehe
I call that the 5lb Knock Knock Test!
"That's not going anywhere!"
I have this heater. And let me tell you it is amazing in the winter.
Any issues with combustion moisture?
May I ask what brand it is?
Excellent, thanks for sharing with us.👍👍👍👍👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
I have a few of these in my garage/workshop. It’s don’t seem to be as dry as kerosene heat.
In South Carolina you can't do anything in the garage from May to November unless you want to broil.
I have a MR Heater gas forced air unit that hangs from the ceiling with vent out the roof. You get very dry heat with no gas fumes, and heats much faster, and equally throughout the garage. Even on a 20 degree day, my garage is warmed up to 65 in 15 minutes. I also lack insulation on my garage door and roof. The heater installed here is more of a spot heater, good for warehouse doors.
Homemade outdoor wood fired furnace is the way to go
I live in the winters where it gets 25 to 28ﾟ I use a oil heater from home depot is home depot it cost a $120 I plug it into the wall bam bam job done my garage never gets below 65 degrees
best part was when he felt that sharp screw sticking out the back and after putting the bracket on and didn't think twice about it 3:14
Chris He gave it the double tap of approval
Good morning, thank you for the video, it is great. Would you please include links to the materials needed or at least the names? Thanks!
I want one! A garage that is, so I can heat it.
Would you do a segment on heating a home with electric infrared heating panels?
Cool video, you guys have inspired so many of my videos on my channel. Thank you
I love that your protection while using a cordless drill OSHA would be so proud. Also this guy needs to upgrade torque screws then he doesn’t need to double tap this work
Your talking about a heater that only heats objects. I bought a radiant heater and mounted it above my workbench where I sit most of the time to tinker. They are hard to regulate and they only heated whatever was in front of it. As soon as I walked away from the bench I was cold again. Mine is electric and not gas as is in this video. I got rid of that heart when I built a free standing shop behind my garage and installed a ''ggarage, /workshop heater. It is electric and I pan to only use it until the wood stove gets up to the right temperature.
I use the same heaters and have for years up hear around Cleveland. They're definitely the most efficient and convenient for ohio winters.
What's the cost for this? This is more for attached garages, right?
I have a woodworking shop and i installed a ductless heat pump. Works great and hasent changed my electric bill.
has the dust loading up the filter been an issue for you?
My floor feels cold. What you recommend. Thank You!
we had those in the recieving warehouse I used to work in... they had a timer on them that you always had to restart.... I hated it...
My HVAC sub made same recommendation for my professional woodworking shop. Be careful of proximity and directional orientation of radiant source to wooden workpieces. Intense heat can quickly warp wood when one surface absorbs the radiant heat directly. I ended up switching to unit heater. Expensive mistake.
Agreed. I was a commercial HVAC technician for over 15 years, and serviced many different kinds of radiant and hanging heaters. Unit heater is the way to go. Especially in a shop that big . I have a small garage/Workshop and would never hang a radiant heater, ever. Got a small Modine i pulled from a small job and my garage = awesome.
@@MrEarbuckets If you were asked about year round climate control for a well insulated 1000 sf garage shop today, would you recommend mini-split?
@@michael.schuler Most definitely. Super efficient. Prices for ductless mini-splits in north america leave a little bit to be desired. but hands down cost per BTU is phenomenal.
its been over 2 years. how is it working and how much does it cost to run, and how what size is the shop. sq ft and ht.
I have a wood pellet stove and two 5KW heaters in my 1500 sq ft shop. Live at 6500 ft elevation in the mountains. Works pretty well
no one cares
@@Fattony6666 apparently you do. Took the time to read the comment and respond
You need a better pellet stove if you need more heaters to heat 1,500 sqft even in the mountains.
I've owned a Enerco garage heater I purchased in 1993. Very easy to install and operate. Been a wonderful and reliable heater. After all these years of use it's is in need is a new control module. Any one knowing where to get one please reply. Thanks
Have you tried Enerco's website? If they don't sell parts there, call them and ask them where they would buy parts when they need them.
Edenpure infrared heater with extra electrostatic filter velcroed on back. All i use.
that was sweet
One or two electric floor plug in convection heaters would, to me, be the better option. Eliminates need for pipe work and vent work. Insulating above attic is key of course.
If you have the circuits for it. One convection heater will usually fully load a 15A circuit (with some safety margin of course), so you basically need 2 dedicated circuits.
@William Murray Top 10 on the list of things I will never care about: Having heat in a garage workshop with no electricity to run tools or lights.
@William Murray who gives a crap about losing heat in a garage if you have no power???
Ayyyy akronite here-this is awesome!
Split system heat pump with 96% gas furnace. Heat pump at temps above 30+- degrees. Gas furnace below 30. A/C In summer! Initial cost is a little higher, but worth it. 96% furnace has sealed combustion.
have to ask is this safe with gas in and around that area and can you use a propane one .I have an unfinished basement that I would like to heat to hopefully warm up the house above also .I keep my ride in mowers in my basement for now ,but planning on buying them a new home .I am in southside VA and had new lennox dual stage heat pump put in 16seer ,but house is still chilly .My walls are 2x6 and floors are insulated .
Awesome! Also glad to see you guys making it over to my neck of the woods!
Instead of using the wall bracket, can I use a set of chains to suspend the heater from the ceiling?
Can you explain more about the vent that was installed to the outside?
Natural gas and propane emit water as one of their by-products of burning. You need to vent that moist air out if possible and you also need to admit a little combustion air so you don't deplete all the oxygen in the room.
We use a potbelly stove feed with scrap wood
As do I. I placed a fan to blow across the exhaust pipe below the choke plate. Barely any coals, 18℉ outside, too warm inside. I also have a small AC unit close to where I do most of my work to keep me comfortable during the summers.
Correct, I am a wimpy old man.
So do I!
That small unit won't heat that space.
And when you run low on scrap wood you have to work faster on projects...just to survive.
I eat a potbelly pig and feed the cats the scraps
That's not the point of the video but if left on continuously with the thermostat it probably can take the chill off enough to work in there especially if the walls and ceiling are insulated and the sale on the garage door are working well
do you recomend a power vent on opposite end to get rid of moisture
Ok that's badass I'm in akron too so this video is perfect! 😂
Surprised they didn’t shove festool drills into his hards for the episode. I also wonder if they bothered to properly bond the CSST gas piping
You really wondered all that?
How to run electrical wire to
shed
You showed stuff most folks already know. I want to know how I run gas lines into my neighborhood?
This is dope
J-swizzle 19 , I didn’t see any illegal drugs in this video.
Open flame + sawdust = BOOM !
Nope
How much did did doing that cost I have a detached garage I'd like to add heat to
O-H !! Lol putting an old furnace in my garage shop. Running the gas line and exhausting through an un-used man door.
Great idea for heating a garage I didn't even think about that for a residential application. They use of big tube style radiant heaters for commercial workshops and they work really well.
I always worked in shops with commercial tube radiant heaters. I put a residential radiant in my large home garage and was a piece of crap! Removed it and used a unit heater. Perfect!
The only difference is the radiant tube heater is vented where as this little sucker is letting those toxic fumes into the space. This is a horrible idea
@@raymondmiller162 I think you’re thinking of something else. Two heaters get banded to the outside
Anyone know how long that jewel will run on a 100 pound propane tank?
Nice French cleat system
Thats a very good heater we have one but its branded under the name enerco.
Hi guys, Please tell me, what about fire danger with dust ?? Thanks,
My neighbor made a wood heater out of an old oil drum...thing gets mega hot! Glowing red! ...Outside its 4 degrees. Inside its 75 degrees!!! NO insulation.
Did I miss something? Why was the thermostat positioned close to the heater.?
I see a fire hazard with sawdust in the air. A boiler outside the room and either baseboard hot water heat or forced air over the hot water heat exchanger.
The answer to his question at 2:13 Ahhhhh here we go, right next to the chemical cabinet. 🤣
Atta boy Richard. Infrared Heat is the bomb. Once the shop warms up it will last for hours as all the heat radiates back into the space from all objects that picked up the heat. Unlike forced air which just drifts away. HVAC contractor here.
Looks like the furnace is pointed to far down. It doesn't seem like the Ray's would make it very far
Did they mention the BTU of the model they used?
I don’t think Richard knows how to use a drill. Every time he uses one he strips the hell out of the screws lol.
I guess that's why he only used 4.
He's a plumber
That is just how an “Impact Driver” sounds.
@@ileanamorales1384 No that’s a regular drill he’s using
That wasn’t Richard using the drill though
with a bedroom above the garage, how may I get this system to work with Gas in my home?
My question is. Looked like he used homeflex gas pipe that Home Depot sells. It is also called CSST (corrugated stainless steel tubing) pipe. Did he bond it or ground it to the electrical panel. That is now code across the country. Thats to avoid pin holes in case of lightening strike in the area. Lightening strikes could cause small pin holes and cause leaks which lead to 💥💥. And I'm assuming Richard realizes how bad that is seeing as how an entire neighborhood blew up in Massachusetts due to faulty gas equipment and pressure increases.
Can I use this in my paint shop?
Was the vent connected to the heater?
i like those heat lamps attached to a propane tank. Those work great.
Propane and propane Accessories
Need a well ventilated area but they work great
That's right. Hank Hill
Screw it in then * bang bang * expected him to bang his hand after the hand shake.
My hot dog heater works fantastic!
Oil stains on the floor used to be keeping cars in there
I think I might have considered a mini split instead..
It is critical that the flame source be at least 18 inches off the floor to prevent FIRES, according to our Fire Dept! That's why Insurance Companies don't like them! We have all seen floor heaters (kerosene/Diesel/Propane/Potbelly Stove etc) used to heat garages. Once I learned this I threw our Kerosene Heater in the Garbage that night and replaced it with a Wall Mounted Infrared Natural Gas Heater, the best move I ever made. That Heater has been in four different houses and was converted to propane because our current house doesn't have NG in the garage. Now after 15 years I replace it with a new Infrared Propane Heater. I highly recommend them.
That's great they dont show the installing pipes I think it's more important to show where and how to secure and that thermostat is perfect where it is under the heat
Not sure why you would put the thermostat that close to the unit heater - going to be cold on the other side of the garage all the time, since it 's registering the heat from just a few feet away.
I wonder how this worked out. Is the entire shop heated evenly? For some reason I'm thinking NO. When you see these there are generally at least a couple of them, not just one for a space that large. I'm skeptical.
In my 1,000 sqft detached shop, 30,000 btu is not enough. I have a convection type Mr. Heater propane wall mount unit and it runs all day long. The shop is not insulated so that would help.
These types of Heaters are Space Heaters like in Home Depots over the Registers.. This Will Not Heat That Garage.. he should of installed a Low BTU Boiler and ran Flex to Duct Work and ran a Couple Runs of Flex and Registers. but what do i know i only did HVAC For 10 years. this is a waste of time and money.
@@Dominick_Calvitto. That is my thought too. They use this style for the outdoor drive through at Chik Filet as well.
@@Dominick_Calvitto. that's incorrect and i say this from first hand experience. I had an HVAC guy install the same exact unit installed in my attached, finished and oversize garage that was 31x28 with 11' ceilings in Kansas. Kept my garage at 68-70 all winter long with zero issues and was a nice even heat across the whole garage. And no, it didn't run all day long to maintain that temperature either. Zero condensation anywhere and no fumes. Worked amazing.
I see a lot of people putting heaters up high up on the ceiling......if hot air rises, why not the floor?
I was told that gas fumes from mowers & gas cans are low to the ground.
Heaters up high eliminates the chance of flame from heater being ignited by gas fumes.
Northeast Ohio represent
How is the size of heater for a garage determined? Mine is about 700 sq ft.
Cut that plywood a little short? Lol
pdxthriftking 503, it was probably a scrap that was lying around.
Terrible
Even if short scrapwood, at least center it over your two outer wall 'studs.' Guys obviously into projects, could have put horizontal studs over drywall and screws into those. Entire support system would be hidden behind scrap piece.
What I dislike about all these videos is that they never show the finished product. At best, doing a freeze frame might give me a glance.
Won't that add moister and condensation?
This is a good retrofit solution. The smart solution is to place pex tubing in your slab when it is poured. That is far and away the best shop heat.
It achieves the same goal, heating the concrete without wasting energy heating the air.
Robert Amos IV Not quite. The temperature gradient in the room will be more uniform with the heat radiated from the floor rather than to the floor. as any objects between the radiant heater and the floor will absorb the heat making the floor temp nonuniform. For new construction, I would definitely go with pex in the slab. However, that is not an easy retrofit.
I said same goal. Heating objects also radiates heat. If you want to get fully technical, heating the top of woodworking equipment might actually do better if you use the shop for limited hours because heating the floor would take a long time to get the equipment heated up so the occupants actually felt that heat. If it was running 24/7 sure, but I would assume this is a part time operation.
Robert Amos IV You can’t beat warm feet! 😁
@@LTVoyager you can if you cant get them to the heat under a table saw!
Any ideas from anyone if someone hasn't been able to get heat , electric assistance , or any plans at all ? What does the expert Richard recommend for solution? Since people are claiming the state I live in is home base :) I'm sure I could be the odd ball and get some type of heat without a issue .
Love Richard, never seen an episode where he didn't sweat during an install!
yeah he makes it look easy... 5 minute install too...i don;t know how he got all those fancy corner woodwork and brackets done. Thermostat was two screws seamless...must have be RF with batteries...lol
Well- I have to assume, you are unaware of the miracle , of video editing. ;)
So how do u vent the carbon monoxide. Also the heater is not pointed outward.hmmmm.....
Thanks for the help I need to hear the garage.
And the option for those of us without a gas line running to the shop?
Chris Emens how about electric lolololololololo
They make electric infrared heaters too. Not sure if they are quite as efficient though. They might be, but could require some major breakers.
my only criticism is the downward angle, imo looks steep
You don't want any portion of a radiant heater to be directed at the ceiling. If it is aimed at a ceiling then it's kind of a waste.
And the fact that the thermostat is right next to the heater
@@garrettducat5769 i get that, but it looks like only the area next to the cupboard will get heat
Home owner preference but its adjustable if needed.
@@kalijasin how is it adjustable? look at the mount at 3:28
What is really really freezing?
Why not electric infrared heater?
What about the toxic fumes?
Radiant heaters are only good if your infront of them. It gets to -40 here get a woodstove
What about a heater if you are planning on spraying lacquer.
Electric or get a extraction fan for your paint area. For a small home shop a cheap stove vent hood with some side walls would be fine.
Average winter temp. in Akron is a few degrees above and below freezing. So not really all that cold so this might do the job. Where I live you this would probably heat a tiny shack. Strangely most of all the commercial warehouse garages etc here have large natural gas fan-driven heaters that are noticeably noisy when the unit starts a heating cycle. They are slightly larger than a small fridge but if it ever fell on someone it would kill them. The upside of these Infrared units is that they heat the floor or whatever they are pointed at which then heats the air above it. Plus apparently, they are dramatically more efficient up to 75% more.
What about insulation? I would have thought that would be the number 1 issue to tackle. Because I could just roll an electric radiant heater and be done with it.
You probably could insulate the exterior wall, but not much can be done about the garage door.
