    New system put in service today

    During the storm of the century, I started to heat water for my slab at 4:00 PM CT today. At 5:40 I had raised the floor temp 2*, from 43-45*. I will keep track of it till about 11:00 PM and will take some pictures when the weather mellows out a bit.

    Slab temperature??

    I'm getting ready to commission my slab heat in a day or two and I'm curious what others have set the min/max slab temp at in their thermostat settings? I think I'll start with a room temp of 60*F, but would the slab temp be set the same?? Any advice would be appreciated.
