I spend most of my time in one or two rooms. I turn the heat down and just heat those spaces when I'm in them. Large savings in cost. I use a 20.00 electric heater next to me. Works just as well. I keep the temp around 65F. I also find it easier to keep the humidity up in winter with colder air in the house because it can hold less water. That said also increasing humidity and holding the temp lower like 60F feels warmer for some reason.
