How Does Electric Heat Pump Work?
If you think of heating or cooling your home, one of the appliances that come to mind is the heat pump. You can use it to both heat and cool your home. In fact, it is considered to be a better choice compared to separate heating and cooling systems. This appliance uses a small amount of energy to transfer heat from one place to another in the house. It typically pulls heat or cold air from the surroundings and uses it to either heat or cool the home. It operates in a similar was as an air conditioner.
Electric heat pumps are highly efficient since they do not manufacture the heat that they distribute. Instead, they usually collect heat or cold air from outside and then moves it inside your house. The heat is transferred by circulating a substance that is known as the refrigerant through a condensation and evaporation cycle. The refrigerant is pumped by a compressor between two exchanger coils. After that, it is evaporated at a low pressure in one coil and then absorbs heat from the surroundings. As the refrigerant heads to the other coil, it is compressed. The pressure increases and causes it to condense and release the heat it had absorbed earlier.
The cycle of the electric heat pump is fully reversible. That is why you can use it to heat as well as cool your home. Since the air outside and the ground always has some heat, you can use this appliance to supply heat to your home even on very cold winter days. Even if the temperatures drop to as low as negative 18 degrees Celsius, there is still some heat in the surroundings that can be used to heat your home. You can use it to save up thirty percent of heat energy compared to other appliances such as a gas furnace.
When buying an electric heat pump, you will need to put into consideration its SEER, or seasonal energy efficiency ratio. The SEER is simply a value that represents how efficiently the heat pump operates. Typically, a heat pump that has a higher SEER rating is considered to be most efficient. When using such as system, you will be able to save more energy, and as a result your electricity bill will reduce tremendously.
Besides the SEER rating of the electric heat pump, it is important to determine the proper size of electric heat pump that will be suitable for your home. An HVAC contractor can help you determine the ideal size of heat pump to use. Things that the HVAC contractor will need to take into consideration in order to help you determine the proper heat pump size include the square footage of your home, the wall insulation, the amount of ceiling, the window area among other important variables. Just because a heat pump is sold at the lowest price does not mean that it is the best deal. The efficiency of the system is what you should consider mostly.
