Radiant Floor Heating Efficiency
I have a brand new home in Northern Virginia. The home has a 9′ high full in-ground basement that is currently unfinished. I am wondering when we decide to finish this in the coming years what is the most efficient way to do so.
In my experience the basement tends to be cooler or cold and damp. We should have adequate drainage through the drain tile system, sump pump, and foundation water proofing.
My main question is regarding the efficiency of radiant floor heating. Because the slab is already poured I would assume that this would need to be an electrical radiant system. Is there any way to retro fit a hydronic system on top of a finished slab at all? Is it more efficient to heat the basement with the radiant system then the forced air? I know that the concrete floor has thermal mass that should hold some of this heat in, but if I didn’t want to do ceramic tile flooring what material would be best on top of this (keeping in mind that this would be a family room type setting).
If the basement is heated using the radiant floor (if this is possible), would it be best to cut this “zone” off from the natural gas heated part of the house?
Any advice for radiant floor heating and/or finishing a basement will be greatly apprecaited!
