I've been experimenting with my thermostat the past couple of weeks to
see how I can save energy. I've noticed that if I keep my thermostat
at 67 degrees my boiler will cycle every hour or two to maintain the
temp - but if I set my thermostat to 66 degrees it will cycle every
4-6 hours. It's been around the 32 degrees outside all week. Is there
a natural temperature that a house can hold for longers periods? If
so, how can I raise that temperature?
