Whole-House In-Floor Radiant Heating
Is whole house radiant floor heating effective in the real world?
Calling out to homeowners with radiant floor heating…
I am looking at constructing a new home in New England, specifically the metro Boston area. A large house approx 4,500 sq ft on 3 floors, I would like to use radiant floor heating throughout, mainly for comfort but secondarily for hopefully lower energy bills.
The house would be well insulated and my concern is that I am hearing of issues of radiant heat and well insulated homes. I have read online:
“When the heating load is very small, the radiant slab has to be maintained at no more than a few degrees above room temperature to prevent overheating, and this means that the slab isn’t likely to be warm to the touch. A slab maintained at 74°F (23°C) will be cooler than an occupant’s skin, so bare feet will conduct heat into the slab.”
If this is true I’m not sure if radiant floor heat would be worth the extra cost over forced air. I am looking to create a comfortable environment especially not cold floors. Have people experienced this is in the real world?
BTW I am looking at a hydronic system, I know that an electric system will probably be too expensive to run. My real question is overheating a real problem in an energy efficient house? One where you can get the floors hot enough to feel warm as the house would be too hot and overheat.
