HVAC Services | Heat Pump

Heat pump water heaters use electricity power 240 voltage and 30-amp breaker some of the electric water heater could be different. Depends on the brand. Heat pump water heater work exactly work like heat pump air condition system. The tank look like regular electric water heater but heat pump water heater you’ll see on the top have condenser unit that have exactly like air condition, they have similar component they use on the air condition system like fan motor, compressor, evaporator coil, capacitor, filter dryer, and use refrigerant heat the water. And if you look at the tank, you look like exactly electric water heater use the same component that electric water heater like heating element, relieve valve, anode rod, drain valve, hot water outlet, cold water inlet, high limit thermostat.

They have a 6 step to understand how heat pump water heater works –

1) A fan draws air from the surrounding environment over an evaporator.

2) The refrigerant in the evaporator coil absorbs the heat from the air and vaporizes.

3) The heated refrigerant vapor moves to a compressor, where it is compressed, significantly increasing its pressure and temperature.

4) The hot, compressed refrigerant then flows through
a condenser.

5) The condenser releases its heat to the water stored in the insulated tank.

6) After transferring its heat, the refrigerant cools and condenses back into a liquid, starting the cycle over.

Why I need a heat pump water heater?

Heat pump water heater is 200-400% efficient which means that you get 2-4kWh of heat output for every 1kWh of electricity to run the pump.
