Basic Structure:
An electric water heater with a heat pump on top, running solely on electricity.
Heat pump is the primary heating stage, with electric heating elements activated during high demand.
Water Connections:
Cold water enters the lower side connection.
Hot water exits from the upper side connection.
Additional piping is part of the heat pump system.
Heat Pump Process:
Hot gas refrigerant from the compressor travels through coils wrapped around the tank, transferring heat to the water.
After condensing, refrigerant passes through a metering device, absorbing heat from the surrounding air before returning to the compressor.
Efficiency:
The system is about 15% more efficient than standard electric water heaters.
In warmer climates, the heat pump can also cool down spaces like a hot garage, further improving efficiency.
