The heating in the new addition is going to be Radiant Slab on grade. We have a walkout basement in a RR style house and the room is going to be off the basement. It will have to be it's own zone. At the same time we're trying to figure out how to heat the rest of our basement slab as this will become finished space also. We're looking into some dry Radiant installations that go on top of the existing slab.
Our basement slab was uninsulated underneath it, which they didn't do back in the 80's. So we laid down a vapor barrier along the whole floor and up covering the half walls and sealed it tightly. We installed 1/2 inch form board since we didn't want to loose to much ceiling height, covered it with wire mesh and then laid down our radiant tubes connecting them to the wire mesh and then poured 3 inches of concrete on top of it giving us a very nice warm floor.
We then built up our knee walls and spray form the all the walls. It came out very nice.
The Baseboard upstairs could stay forever. But I really like all the things I have been reading about Radiant heating and I would like to convert the "upstairs" to Radiant and remove the baseboard.
We have a raised ranch that we had just bought and it had electric baseboard heat on the first floor. We took it all out and installed staple up radiant floor heating underneath it. We loved the warm floors we had last winter, to bad it was all heated with oil.
Once you do it you'll be asking yourself why you didn't do it sooner?
Which is why I asked if you plan on removing it then why not save yourself some trouble from trying to tie the couple different systems together and just go ahead and remove the baseboard and throw up the radiant floor now?
hehe, you make an excellent point. I'm nervous I will run out of time between the addition (not sure when it's gonna start) and putting up the radiant flooring. I didn't want to put up the radiant flooring b/c the 2nd part of our addition involves blowing out our entranceway way 14' and adding a 3 car offset garage on the side of it.
If I put the radiant in now, there will be some floor that has no loop under it.....
On the other hand, I could always use that extra zone from the baseboard to heat a hot tub in the future
That's my dilemma right now..... thoughts?
I'm glad you guys REALLY like the radiant floor! I found a dry system that will only take up ~1" of floor space on the existing slab and includes some insulation as well.
What size tubing did you use in your retrofit of the basement floor.
You make a good point too. Perhaps we will be happy with the radiant downstairs and the baseboard upstairs. The only retrofit we may need to do is break up the upstairs into more zones, and put radiant in the bathrooms.
In the enf the "upstairs in our RR will be only bedrooms and 2 bathrooms. The "basement" will be our kitchen, and the new "sunroom" will be our living room. Keep in mind our basement is at ground level and it walks out to the lake.
