I'm building a new house and I want to use under floor hot water for heat. The local gas company will install 500 feet of line free and will give me 550.00 rebate to use on appliances, so I'll have a water heater and another water heater for the underfloor heat. I am going to use PEX piping and will install a manifold with a valve to each zone so I can adjust it after starting it up. I need to find the heat transfer plates, the al. pieces that help transfer heat to the floor. Does any one know where to find them? I've been told that they really help in heating the floor by pros, and been told that they aren't needed by others. Any imput? Thanks, Nat

I put a system in the concrete floor of my shop (approx. 2200 sq. ft) about 4 years ago. I've used a good grade electric hot water heater which will do OK until the outside temp gets down below 15-18 F, then the system works hard to keep up. I only keep the inside temp about 55-57 F. The shop is very well insulated.

The electric co-op took away my discount for the electric for heating the shop (long story...). I plan on retrofitting the system and substituting a neat Japanese LP boiler by Tagaki that has superb reserve heating capacity sometime in the next year. It's very reasonably priced at about $1000 (see: >Link

I love the floor heat. Best way to go if you can afford the up front costs.

Nat,
I just finished building a house with in-floor radiant heat. I used the above floor approach (nailing the tubing to the sub-floor and covering it with 1 1/2" gyp-crete). If you want to know some more about this e-mail me and we can talk about it. I'm also a mechanical engineer by trade (for what thats worth). Lots of things to consider doing this type of system- its not cheap so want to do it right the first time.

I have a radiantec system in my slab on grade addition. Works well. They are good people and top notch equipment.

One word of caution--check with code officials, in Michigan, according to the State Code Officials, you cannot use a domestic water heater to heat the water for space heat use. It must be a boiler. That is at the state level. I searched for some logic but have never been able to come up with it.

That being said, you will want to check with local code officials, if you are in a regulated area--I also recognize that in some states and areas a man'shome is still his castle.

Nat;
I installed radiant underfloor heat in our 100 year old farm house a couple years ago. only on the first floor with acsess to the bottom of the floor from the cellar. We got the aluminum plates to which you refer from the dealer who sold use the boiler. They are from Germany as is the boiler (Buderus) and pex tubing. If you are putting the tubes in concrete I don't think you need them. If you are putting tube under a wooden floor like I did it won't work with out the aluminum. Aluminum conducts heat better than just about any metal and these plates transfer heat from the tube to the floor and spreads the heat out over the floor surface. With out them your floor will have hot and cold stripes. They are simple to install they have U shaped bend down the center that clips right over the tube then you staple it to the underside of the floor with an air stapler set light enough to not drive the staple clean through the alumninum. The plates should have a bit of clearance from one another to allow for expansion when hot.
Remember, the more of the underside of your floor that you have covered with the plates the more evenly distributed your heat will be.

It's the nicest form of heat you can install. You will love it.

Mine will be under the floor not in the floor. I appreciate the help. Greg, are there any specific engineering problems with using a natural gas water heater to heat the water? The winter temps here are lows of 20's daytime high in the low 40's. It seldom gets any colder, but that is to cold for me. I was appling the waterproofing to the foundation today and had to build a fire to keep the tar warm enough to roll on. High today was 37, but unusualy cold for us

Lots of systems use water heaters, just make sure local codes allow it if you have to pull a permit or get inspections. The typical water heater is not the most efficient thing in the world (although they are getting better) but since the average water temp to the radiant system is in the 120-130 range they will certainly handle the load. The most important thing is to insulate the joist space below the heated floor or else a big percentage of the heat will be lost to the area below the floor. If you don't mind give me your e-mail and I'll send you a design/installation manual for the company whose material I used. Will work for any companies stuff, just a good common sense manual. I think just hit my email thing in the response bar and I should get it.

Greg, I can't seem to get to your e-mail, so will ask here. I would like to know about how much gyp-crete weighs per sq ft. Any idea? I will have tile every where in house anyway. It would certainly be easier to put it down than up. I have a pretty good bit of concrete exp, and have several friends that do it for a living. It wouldn't be a problem to set the door height to allow for the extra height now, but would be if I had the framing done. Any opinions on in floor vs. underfloor besides the weight issue? Thanks, Nat
