I have a small house that we added a second floor to. The gas hot
air heat is in the attic now and feeds the whole house through ceiling registers. Two zones, one for each floor. The first floor always seems cold in the winter, with the second floor nice and cozy, even though thermometers read the same on both floors. Naturally the firt floor hardwood floor is like ice with a unheated crawl space under it. We've tried adding humidifiers on the first floor but that doesn't help. As a solution I was thinking of putting in a radiant heat system under the first floor and feed it from my water heater. This system hopefully would warm the floor a little downstairs and make it more bearable in the winter. Naturally is nice and cool on the first floor in the Summer! Has anyone done any radiant floors?
