HI,
I set the thermostat timer for a minimum overnight temperature of 45
degrees, to heat to 70 at 6:30 AM. Effectively, this leaves the furnace
turned off overnight. I figure that saves wear on the furnace / fan and
saves fuel costs overnight.
However, I heard on a radio program that thermostat timers should
only have a max differential of about 8 or 10 degrees.
Anybody know what the best settings are?
use 10 degree setbacks for best efficiency and least problems
