Approved Heat Pump Water Heater Products Under VEU Program

7 min readAug 14, 2023

Heat pump water heaters are a type of water heater that uses electricity to move heat from the surrounding air to a water tank, rather than generating heat directly. This makes them much more energy efficient than traditional electric water heaters, and can save homeowners a significant amount of money on their energy bills.

Heat pump water heaters work like a refrigerator in reverse. A compressor draws in air from the surrounding environment, and uses electricity to heat up a refrigerant. The hot refrigerant then flows through a coil in the water tank, transferring its heat to the water. The cooled refrigerant then flows back to the compressor, and the cycle repeats.

Because heat pump water heaters do not generate heat directly, they are much more efficient than traditional electric water heaters. In fact, they can be two to three times more energy efficient, which can lead to significant savings on energy bills.

In addition to being more energy efficient, heat pump water heaters also have a number of other advantages. They are quieter than traditional electric water heaters, and they do not produce any emissions. This makes them a good choice for homeowners who are looking for a more environmentally friendly water heating option.

The main disadvantages of heat pump water heaters are their higher upfront cost and their potential limitations in colder climates. Heat pump water heaters work best in climates with mild temperatures, as they need to be able to draw in enough heat from the surrounding air to heat the water. In colder climates, heat pump water heaters may not be able to provide enough hot water, and may need to be supplemented with a backup heating source.

Overall, heat pump water heaters are a great option for homeowners who are looking for a more energy efficient and environmentally friendly way to heat water. They can save homeowners a significant amount of money on their energy bills, and they do not produce any emissions. However, they are more expensive upfront than traditional electric water heaters, and they may not be suitable for all climates.

Here is a table summarizing the pros and cons of heat pump water heaters:

1. A fan draws air through an evaporator. Thermal energy within the air is transferred to a liquid refrigerant, causing it to change into a gas.

2. The refrigerant gas is then drawn into a compressor, which increases the pressure and as a result increases the temperature.

3. A condenser (heat exchanger) then transports the hot gas refrigerant around the outside of the water tank. This heats the water inside the tank, and the gaseous refrigerant reverts into a liquid.

4. The pressure of the refrigerant is reduced as it goes through an expansion valve and returns to the evaporator for the process to start again.
