The Energy Department says that even turning thermostats back 7 to 10 degrees from their normal settings for eight hours a day can save as much as 10% a year on homeowners' heating and cooling ...
The Department of Energy recommends setting the temperature to 68 degrees Fahrenheit in winter weather. Anywhere near 70 degrees is a good number to aim for when it gets cold.

The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.
Heat pumps therefore have a provision for occasional defrost of the outdoor coil. This is done by reversing the cycle to the cooling mode, shutting off the outdoor fan, and energizing the electric heating elements. The electric heat in defrost mode is needed to keep the system from blowing cold air inside the building.
A ground source heat pump is used in winter to extract the warmth from the Thermal Bank to provide space heating via underfloor heating. A high Coefficient of performance is obtained because the heat pump starts with a warm temperature of 25 °C (77 °F) from the thermal store, instead of a cold temperature of 10 °C (50 °F) from the ground.

Whether you have a furnace or electric heat, knowing the right time to turn your heat on may prolong the system's life, prevent damage (like frozen pipes), and optimize energy efficiency. 1 ...
The role of a heat exchanger is to transfer heat between two mediums, so the performance of the heat exchanger is closely related to energy or thermal efficiency. [11] A counter flow heat exchanger is the most efficient type of heat exchanger in transferring heat energy from one circuit to the other [citation needed].
