The Thermostat As Key To Furnace Efficiency
A lot of people look at upgrading a furnace as the key to improving the efficiency of their heating system. While a furnace upgrade should help, it is not the whole story. You can have an energy-saving furnace, but without the right thermostat, you will never be able to tap into its full potential. If you have an older thermostat that only has one setting, then it is high time that your replace it with a programmable furnace.
