Question

New floor idea?!


So recently I made a thread about taking down a wall upstairs in the bedroom. The carpet that is currently down is completely destroyed, so we are going to put in a new floor.

now the question is, i am thinking since it's on the 3rd level, where the ducts from furnace is losing heat by the time it makes it up to the bedroom, what do you guys think about a radiant floor?

we dont have access to under the subfloor, so i think the best method is a electric mat system above the subfloor.

so:
1. does it make sense to put a radiant floor in?
2. if we did, what kind of finish floor should we install? i read that tile is best, but i dont really want tile in a bedroom.
3. how DIY friendly is this? i picture myself laying the mats down, and then making the connections. easy right?

what are you guys thoughts please

I've done a couple of the electric radiant systems recently, both the pre-woven mats, and the cable that you have to lay down yourself. The mats are definitely easier, but more expensive. Depending on the size of your room, the cable may be the most economical (my kitchen is 13x18, and I did 240V cable)

It's not that hard to install, as long as you can follow directions well. The most important part is very carefully measuring the space you will heat, because you cannot alter the size of the mats or cable once you purchase them. There are guides online that tell you how far apart, how far from walls/appliances/etc and can give you a good idea.

From what I've read also, you can install it under all different types of flooring, but your solid floor is going to be the most efficient. Perhaps a wood floor would be a good compromise? just a suggestion, I personally don't like carpet...

Is this a room that is typically cold? Attic space, of sorts? I've also read that radiant floor heating can be used to actually heat a space, and IMHO if that were the case, I would want to pick a more efficient type of flooring (like hardwood) to get the most out of my electricity...

thanks for your note. you have me a little confused though. i read hardwood is not good for radiant heat because the heat ends up cracking the wood over time.

did you use the cable kind? how much did it cost?

yes this is attic space. the size is about 15x10 or so

I don't remember specifics about the wood, as I put mine under tile (bath) and slate (kitchen) but I remember a chart that talked about heat transfer(???) and the different efficiencies of different materials, carpet, tile, hardwood, etc. Stone/tile is the most efficient, I think, followed by wood, and carpet is last.

I just poked around another thread about hardwood and radiant, and the guy that was doing it said something about bamboo being the best suited. Maybe look into that? perhaps one of the fake wood floor, or nicer laminates, if you're trying to avoid tile...

My cable, for est. 230 sq feet (I'm pulling out of my memory here, so forgive me if I'm off a little...) was about $900-ish. That's taking out footage for my cabinets and appliances. With an attic bedroom space, I don't think you have to work around anything like that, just whatever the shape of the space is. I got both the mats and the cable from thermosoft. They have all kinds of measuring and planning guides, and I just looked, they have another type that goes under floating floors. Check them out, at least it will help you get an idea of square footage, and approx pricing. Oh, and they're always running a 50% off deal. At least the dozen times I've looked at their website!

It might be easier to install a fan booster. I don't personally have experience with these, but I know they are meant to help carry to hot or cool area further. Some engineered wood floors can go over radiant heat, just be sure to check what the manufacturer says about it. Hope this helps.

Also remember that heating mats are not to heat the room. All they do is warm the floor a little.

so here is the floor after we tear up the carpet. for those just joining, originally we took down an interior wall (see my other thread), and this was where the bottom plate was sitting on. so do we need to install new plywood decking to make it flush again? and how do we do this? just screw it down 16 on center to the floor joists below? (in this pic you can see the joists running perpendicular to the subfloor that is exposed. but there is a good inch gap)

Heating mats are there just to bring a little warmth to the floor and not to heat the room...
