The basic principle behind commercial HPWHs is similar to that of a refrigerator or air conditioner, but in reverse. The system consists of several key components, including an evaporator, compressor, condenser, and expansion valve. Here's a simplified explanation of the process: commercial heat pump
This cycle allows HPWHs to transfer heat from the air or another source into the water, providing an efficient method of water heating. The energy efficiency of an HPWH is measured by its coefficient of performance (COP), which is the ratio of heat output to electrical energy input. Modern commercial HPWHs can achieve COPs of 3.0 or higher, meaning they produce three times as much heat energy as they consume in electrical energy.

Types of Commercial Heat Pump Water Heaters
- Air-Source Heat Pump Water Heaters: These systems extract heat from the surrounding air. They are the most common type of HPWH and are particularly effective in moderate climates. Air-source HPWHs can be installed indoors or outdoors, depending on the design and requirements of the building.
- Water-Source Heat Pump Water Heaters: These systems draw heat from water sources such as lakes, rivers, wells, or even wastewater. They are highly efficient, especially in applications where a stable water temperature is available.
