Does anyone here have experience with–for want of a better phrase–a slab thermostat? We have RFH. Our Wirsbo thermostat measures ambient temp at 4′ level. Problem is that the solar gain from a 480 sq ft window wall raises room temp quite enough to turn off the RFH before the slab is satisfied. So at night, the slab hasn’t sucked up enough heat to start giving it back. So it gets cold, the heat goes on, but the slab is slow enough absorbing the RFH that you don’t benefit right then. It’s almost like the RFH and the solar gain are doing a bad dance to different drummers.
HVAC contractor offered possibility of using slab temp as an override to the thermostat (i.e. turn off heat at 70° unless slab is < 65°, or whatever). He hasn’t done this yet and is researching. I’m waiting for return calls from Honeywell and Wirsbo–fat chance. Figured I’d check if y’all had experience w/ this. Thanks.
