Re: Radiant Floor Heating: Electric vs Water Retrofit


@Chris616 Yeah, our boiler has a range of like 90*F to 190*F. The HVAC guy said we just need some thingy's for whatever temps we want that particular closed loop to use. Your link calls em "mixing units" - works for me.



^ that is probs what we should do because we have "exposed" baseboard (like just the fin radiator parts on bare copper tubes) heating the basement as a pipe freeze prevention method (and I do think it keeps the interior downstairs a bit warmer as well.)

Re: Radiant Floor Heating: Electric vs Water Retrofit


@Mystriss ,

I almost envy you. Almost. You have so many options available to you.

You don't need to do gypcrete. It is a great way to get a thermal mass, but it is not as needed I once thought. (But, if you can do it, all the better.) It is more important with electric grid/mat than with hydronic.

You can always use self-leveling compound.

For hydronic, it is more important to get heat distribution. Aluminium plates work well with that. Since you are going to be running new tubing, take a look at warmboard.com. They have a system of of all-in-one track, heat distribution, etc and sub-floor that is quick and easy and promotes even heating. But, it's expensive.

There are other systems out there as well. Plus you can route your own. Or you can use strips of plywood and aluminum plates.

If you don't want to lose any height, you can do the staple-up method. It works well, I like it. It can do double duty and heat both upstairs and downstairs. Or you can insulate and redirect. And you can use the aluminum plates to promote the heat distribution.

If you need spot heating, you can use the electric mats. You can also use transfer plates as mentioned earlier. You can also use toe kick panels that use forced air and the hot water.

Re: Radiant Floor Heating: Electric vs Water Retrofit


@ktownskier ooo Warmboard.com sounds awesome. My husband would be much happier with a premade panel than routing our own + they have the manifolds, controller units, and they can do the layout for the runs for us too. Perfect! I'll give em a call next week

[QUOTE=Mystriss;6029807]Which do you think is better on the matrix of efficiency, comfort, and ease of install?

HALP!! /QUOTE]

If you have not started your project yet, you should really consider placing Pex Al Pex water heating in the ceiling. Way less disruptive, a lot cheaper, you supply the same temperature of water through the home (80 to 90 degrees) and a lot more responsive if you wish to change the temp.

Oh nice I'll def. keep that in mind. I imagine that works great with radiant floor heating. Was it specifically designed for it?

We've had to put the radiant floor heating on hold for another year or so, kinda blew my allotted budget on a big pallet of vinyl laminate flooring instead of radiant. That ended up being our "compromise" - aka he won the argument, but I got some pretty floor jewelry out of the deal


I'm gonna make another go at getting radiant heat in when I replace all the sheetrock ceilings - stupid popcorn.

Ceiling hydronic heat is the new buzz. If you have any questions you can message me.

Reaction time for heat change is less then 10 min.
Water temp range inside pex 80-90 degrees. A water temp of 88 degrees can carry just over 55btus/sq. Most homes today require less than 30btus/sf.
