The normal wintertime temps will be in the upper 40's, low 50's during the day, 30's and 40's at night. That's at the heighth of winter, January or so. We could probably save a bit on the wintertime heating if we did like we were supposed to and kept the thermostat on the same temp all the time (more efficient for a heat pump) but we both like it cool at night so will turn it down to 60 or so, and then back up to 68-70 in the morning which causes the auxiliary heating to come on. I really need to look into getting a programmable heat pump specific thermostat.
My problem is I'm very cold natured and will even get cold in the air-conditioning in the summer
! While 95 is pushing it, 90 degree heat doesn't phase me a bit!
