First, love this site! Next, I'm building a large (2500 sq ft) modified ranch in Mass. We're heating with hydro-air. My question is this, the family room has a cathedral ceiling with a loft at one end. My contractor and I feel the hydro-air will not be very efficient here, as the air is going to rise up to the loft. We decided that we're going to run a seperate zone off the boiler for radiant heat to heat (in addition to the hydro-air) the floor in the family room.
My wife wants hard-wood floors in this room. Isn't the radiant heat going to cause hardwood to buckle?
We're using the radiant that is installed in the bays in the basement, if this makes a difference.
