We've been in the 30's at night and 50's during the day. We turned the heater on (we don't have whole house furnaces in this part of the country since there is no natural gas). We turn it up just enough to take the chill off in the morning and at night before bed time. Other wise, the sweaters have come back out and an extra blanket has been put on the bed. It is waaay too early for using much propane yet. We save that for when it's MINUS 30F. Ha!
