<p>I do think it is very reasonable to turn the heat way down at night, in our family we prefer big quilts and breathing cooler air so our thermostat is probably at 50 in night. I don’t want to breathe heater air when I sleep.</p>
<p>The winter that we had a completely empty nest we kept our thermostat at 55 during the day and used space heaters in just the rooms we used. With all the kids at college and the tuition bills, we felt it a smart way to cut down, but I would never do that with other people here! In our case an electric heater in one or two rooms was cheaper than gas heating the entire house.</p>
<p>We have always heated during the day to 64-65 and in the evening to 66-68 when people are sitting around. Yeah, we are stingy on heat, but always turn on a room heater when people are here.</p>
