I have a Radiant heat (Boiler) to gain extra space we are considering changing the wall radiators into under floor radiant heat. My question is since some of the wood floors have been in there since the house was built in the 50's. I am guessing there is 1x2's between the subfloor and the floor boards. Would the the traditional retrofit options like Wirsbo Joist Trak to be installed from the basement. Would it provide enough contact to transfer the heat through? I know in the kitchen/bath were the floor is resting on the subfloor it would work. Just not sure about the oak floors.
