Basics of a Heat Pump Hot Water Heater
A heat pump hot water heater, also known as a hybrid water heater, is a type of water heater that uses electricity to move heat from one place to another instead of generating heat directly. This makes it a highly energy-efficient water heater option.
The heat pump hot water heater has three main components: the heat pump, which absorbs heat from the air and transfers it to the water; the electric heating element, which provides additional heat when necessary; and the storage tank, where the heated water is stored. This combination of heat pump technology and traditional electric heating elements allows the heat pump water heater to provide a steady supply of hot water while using less energy.
How a Heat Pump Hot Water Heater Works
The operation of a heat pump hot water heater might sound complex, but it’s actually quite straightforward. Here’s how it works:
- The heat pump component of the water heater extracts heat from the surrounding air.
- This extracted heat is then used to increase the temperature of a refrigerant, creating a warm gas.
- The warm gas circulates through a coil that surrounds the water storage tank, transferring its heat to the water.
- Once the heat has been transferred, the cooled refrigerant is compressed again, and the cycle repeats.
While the process is efficient, it’s important to note that heat pump water heaters work best in mild to warm climates as they rely on the heat in the air. In colder climates, the electric heating elements may have to work harder, reducing the overall efficiency.
