Gas heating systems use the combustion of natural gas to generate heat. While this may be the most common of whole-home heating systems, it’s not the best choice for every home. Electric heating systems can be highly efficient, if you choose the right one. Many electric heating systems use electric resistance to heat up coils as a fan blows warm air over them. While these can be efficient, the amount of electricity necessary to keep you warm comes at a high cost on your monthly bills.
The electric heating system we recommend to many homeowners, especially those in warmer areas like ours, is the heat pump. That’s because a heat pump is used for both heating and cooling, and it is highly efficient for both, especially in warmer climates.
The Refrigeration Process
Heat pumps actually use refrigeration to heat a home, something that may not seem so logical at first since refrigeration is usually associated with cooling. But the refrigeration process actually involves heat exchange, moving heat from one area to another.
Refrigerant, a chemical blend, is able to absorb heat from the air as it converts to its gas form. In cooling mode, a heat pump moves heat from the inside unit to the outside, absorbing heat from the indoor air and releasing it outside once it turns to a liquid. It continues to change from liquid to gas form, cooling the home as a fan blows over the indoor coil when the gas absorbs the heat.
The Reversing Valve
The reversing valve of a heat pump is what sets it apart from the conventional air conditioner. This component allows the refrigerant to switch direction. Now, the refrigerant changes to its gas form outside, where it absorbs heat from the air around the outdoor unit (and can do so even in very cold temperatures, though efficiency may drop slightly). Heat releases as refrigerant condenses (turns into a liquid) inside of the home at the indoor portion of the heat pump. There are additional valves as well that help to reroute the refrigerant so it can carry through with the heating process.
