I won't bother making a poll. Let me just pose the following questions: How many of you who set your thermostat low have "warm air" heat, i.e. gas, oil? Conversely, how many who have "cool air" heat (heat pumps) set their thermostats high? We have oil. When the heat comes on the air feels nice and warm and so we have the thermostat set low and stay comfortable. When I was a kid we had a heat pump and when the air came on it always felt cold no matter what the thermostat said. I prefer the oil heat even if it is more expensive at present.
