How low can I drop thermostat without freezing pipes?
I recently purchased a slab home with in floor radiant heat. Slow heat up times coupled with fast heat loss & high heating bills make me wonder if the slab was properly insulated. I am considering relying more upon the backup forced air unit to heat
Tough question! As to forced air heat, probably not, for it will maintain the temp of the air, not the slab...and if you use both, the floor heat will never come on! You might want to call a furnace man and check out the possibility of adding a 50% antifreeze
