I used a free trial of LoopCad software to design all the loops for my house and it worked great. I will be reusing it for the driveway next. The 30 day trial was plenty for me plus I could put it on other computers or virtual machines should I need more time. I believe it can generate a materials list or I may be thinking of the Watts Radiant Works Pro (2 week trial). It's pretty slick and will take into account your geographic location in calculations.
Does it have the settings to do snow melt on outside concrete? I ask because I have read where the layout of indoor heating and slab heating are different in that indoors you run along outside walls first because that's the greatest heat loss whereas a slab you want to heat it evenly.
Hi there, we are looking to do this hydro snow melt system underneath what will be a paver driveway. Are you able to speak to the cost efficacy for this when it's being used for snow / ice melting? Great video and thanks for sharing it!
Hi Blaine. I'm very impressed with your project. I'm going to be installing a new driveway and want to install a snow melt system like you. From the outside, it seems like a simple thing to do. But, I can see that it requires an incredible amount of time, calculations, countless decisions, and attention to detail, which it seems like you dealt with perfectly. Could I pick your brain for some tips?
Blaine, great video I wondered what part of the country you are in? (Weather Zone) Have you run the system through a snow event?? Last question is how or what do you use for make up water and head pressure for expansion and any air bubbles? Like the DMF150 Digital PRESSURE PAL Hydronic Mini System Feeder (4.6 Gallon)?? Love to see a video of servicing and glycol adding!
I am in zone 5 (Denver). I have used it several times and it works well for what I designed it for. My driveway doesn't get any sun and stayed icy all winter if I didn't shovel before it was driven on, so I really just use this to melt the ice enough so I can clear it off. Since this is a closed-loop system separated by a flat plate heat exchanger from my boiler system, I don't have a make-up water valve installed; I just have an expansion tank. Sorry, no video yet of servicing the glycol, but I might change the circulator to a bigger one and maybe I will make one then. I have a solar domestic hot water system that I run glycol in so I have a bit of experience.
@@bp3inden Thanks Blain, You must have done a great job bleeding the system to maintan the head pressure with the accumulator. Thank you again for the info!
Interesting. I have extensive experiences of the hydronic snow melt system. I own a technical consultant company in Sweden specializing in the field. It is a shame Uponor in Us and Canada did not take care of old ”Wirsbo”-know how better. After all, Wirsbo invented the s.c Meltaway system in the early 70-s. Thats when we learned not to use the same pipe layout principles as that of the indoor radiant floor heating. Single pipe in sinus pipe runs over the surface is no good, not even for the heat distribution on the surface, but also gets difficult to install all those 180deg turns with a relatively stiff pipe. The correct way is not well known in Sweden either. It could be called parrallel runs. Supply and return pipe goes side by side all the way, creating even surface temp and melting. You can then run higher deltaT over the loops and use longer loops. You get a higher heat output without running giant pumps. I hope your system works out well for you. I suggest running it on low deltaT, high flow, to minimize temp variations on the surface. Take care!
You are not wrong about the layout. I did research the parrallel run and decided the benefit for my purposes was not worth the effort and opted for the high flow-low delta T . Keep in mind, this was for my own driveway and the only person I had to please was myself.
@@bp3inden ok, great! And on the positive side you have a concrete installation that has excellent heat conductivity. If your loops are not too long you can get good performance with a reasonable pump size. Normal loop length in southern Sweden, running at deltaT=15 degC, with 25mm pipe, is 200m.
@@MrWipex What are your thought about insulation? 1" or 2" thick, reflective blanket instead of foam board. What insulation method best for effective snow melt.
Very nicely done. Quick question: Any idea how much of your boiler energy goes to snow melting? Do you keep the baseboard heaters running while snow melt is also on? In other words, is your boiler enough to heat both snow melt and the home itself?
It is not a problem for me since the snowmelt system is only on for short periods, I heat my main living area with wood when its really cold, and I have 4 zones in my house. A professional would not have done what I did and would have insisted on a larger boiler, but the beauty of doing things yourself is you get to use a little common sense.
I enjoyed your video. I have done heated floors in a home but not a snowmelt system. I would like to find information to determine safe thermal input for snowmelt driveway/sidewalk. How fast can I inject heat without damaging the concrete.
There is a big difference of opinion in that, but I do remember watching a video where a guy shocked his driveway with maximum heat to prove that it is not possible to crack concrete with a hydronic system. There are some standard numbers out there but I don't remember where I found them. In my case, I did get one hairline crack in my driveway that was directly above one of my tubes and even followed the turn at the end a bit, but I don't know if it was because of heat or maybe the tube was too close to the surface.
So being In Denver, where you litterally get tons of snow, with heavy snow you just loosen the grip of the snow/ice from the driveway, then shovel or snow blow? I make that assumption because melting say a foot or more of snow would surely take many hours.
Yes, the original idea was to just loosen the ice in the area that never gets sun so I could scrape it off, but I found it works well to melt off even a foot of snow. Keep in mind our show is usually pretty light and fluffy.
The system ris filled with a glycol mixture and will not freeze. I had to use a heat exchanger because my boiler system is not filled with a glycol mixture.
I did several time-lapse videos but they are kinda like watching paint dry. I did include a still shot of it in action at the very end of the video if you want proof that it works.

Thanks for the tip. I wish I had known about this when I designed mine, but so far so good.

This is awesome, thinking about doing this to ours. do you have any issues with the melted snow icing over after the boiler kicks off?
No, Colorado humidity is very low and it always drys off quick.

Did you design any time of drainage for surface water? If not would you if you were to do it again. Just wondering about ice buildup off the slab
No, I did not worry about drainage as it is such a small area and it drains right into the gravel driveway with no problems.

Cool, thanks for the reply!
Do you do time lapse videos? I saw a guy do the same for his driveway.
Of course I did...lol. They are not very exciting so I didn't post them.
Jakiego przekroju są rurki? Ile pętla ma długości?

If you don't use the system, will the water in the system freeze?
The system ris filled with a glycol mixture and will not freeze. I had to use a heat exchanger because my boiler system is not filled with a glycol mixture.
Just curious, what model pump you used?
Unfortunately I left all that info with the subsequent owner.
Any videos of it working?
I did several time-lapse videos but they are kinda like watching paint dry. I did include a still shot of it in action at the very end of the video if you want proof that it works.
Where does the water go
It just drains right into my gravel driveway at the end of the concrete section.
No disrespect, but what’s the point of doing this area? That huge driveway still gets plowed right?
This area doesn't get sun during the winter and once the ice builds it is there for most of the winter.
No sir, this is not DIY
Well, somebody does it. Might as well be yourself.
Maybe not DIY for you, but this is definitely a DIY project with some basic boiler/ plumbing knowledge. I did it myself, works great!
Check out videos of the electrical units. much less complicated. I can do basic plumbing and even I would never take on this craziness. LOL
