How Do Heat Pumps Heat?

temperature meterLiving in Atlanta means experiencing hot, muggy weather throughout the long summer season. While your air conditioner definitely sees more time on the playing field than your heater does, though, you cannot afford to overlook the importance of having a great heating system installed in your home. If you are serious about living in comfort year-round, you need to take the chillier nights of winter into consideration. Even so, we understand why some homeowners lament the fact that they need to have independent heating systems installed.

We also hope that you understand that you don’t need a separate heater in order to heat your home effectively when temperatures do drop below comfortable levels! With a heat pump in place, you can actually use the very same system to heat your home in the winter that you do to cool your home in the summer. It may sound too good to be true, but we assure you it’s possible. Read on, and let us know if you want to enjoy better heating in Atlanta.

How the Heat Pump Works

During the summer season, when temperatures are at their highest, the heat pump simply works like a traditional central air conditioning system. The refrigerant in the system evaporates in the indoor evaporator coil, which allows it to draw heat out of the air passing through over that coil. The warm refrigerant then makes its way outdoors, at which point it travels to the condenser unit and is condensed. By condensing the refrigerant, its heat is released and the cycle just continues until the desired indoor temperature is met.

Now, the major difference between a heat pump and central AC is the fact that the heat pump can actually reverse this method of operation. A component called the reversing valve allows the refrigerant to flow in the opposite direction, and the function of the system’s coils is reversed as well. Now, the refrigerant evaporates outdoors,  drawing heat out of the air outside. Even in the winter, particularly during mild ones like ours, there is heat to be had.

The refrigerant is then compressed to further boost its thermal energy. That hot, compressed refrigerant travels indoors to the indoor coil, now functioning as the condenser coil. There, the refrigerant is condensed, and the heat that it releases is used to heat your home.

The Benefit of Heat Transfer

The most obvious benefit of using a heat pump to heat your home is obviously the fact that only one HVAC system needs to be used for year-round comfort. That is not necessarily the greatest benefit of the heat pump, though. Most people would consider this to be the incredible energy efficiency with which heat pumps are able to heat homes.

Because no new heat is generated, with the heat pump instead opting to transfer existing heat into the home, it offers up one of the most affordable heating experiences out there.
