I just bought a home that has hydronic radiant floor heating throughout the house. First floor has the Pex piping set in the concrete slab and the second floor is part of the subfloor. There is a lot of carpeting that I want to replace with an engineered wood floating floor. My research tells me that floating engineered flooring is the best choice over radiant heat. Question is what underlayment to choose to facilitate heat transfer and not insulate the floor from the radiant. Also are there certain types of engineered flooring that I should look for that work with the heating system?

Thanks.

 

Bump.
Is there any particular type of engineered flooring that is best over radiant heat and what is the maximum surface temp you should get the engineered hardwood up to?
