Heated tile floor

[rondog]

We sell that stuff at Home Depot, and it's my understanding that it's mainly just to heat the floor enough so that it's not cold to walk on, not intended as a "heat source" for heating the house.

Now, the hot water systems in the floor with PEX tubing is another matter. I DREAM of having a shop/garage built that way! Those are awesome! Imagine walking in your shop into a cloud of warmth, and everything in there is the same temperature. Tools, vehicles, floor.....you wouldn't even have to have it that warm, say 55-60, and have a supplemental heater to bring it up to working temp when you're in there. Just keep it warm enough to keep the chill off. Or warm enough to heat your whole house that way. Maybe someday.....
