What Is A Heat Pump Water Heater?

A heat pump water heater is an electric water heater with a condenser that uses the heat in the ambient air to heat the water inside the water heater. When the temperature gets to cold, the electric resistance elements turn on the heat the water, like a traditional electric water heater.

How Does A Heat Pump Work?

How a heat pump works diagram

A hybrid water heater, heat pump water heater, or electric heat pump water heater works by having a fan pull in the surrounding air and pulls it over what is called an “evaporator”. An evaporator is essentially a series of refrigerant-filled tubes.

The heat is then transferred to the water from the refrigerant inside of the tubes, leaving the cold dry air to be released back out into the room where it had originated from.

However, if the temperature of the ambient air drops below a certain temperature, the heat pump water heater will then act as a standard electric water heater. There is also a hybrid mode that is the standard factory setting and it utilizes both the heat pump and the regular heating elements to maximize efficiency.

Which brands of heat pump water heaters do you install?

The brand of heat pump water heaters that we generally install in the majority of our service areas is Bradford White Water Heaters, particularly the AeroTherm Series. These water heaters are energy star qualified and can connect to WIFI with an app. Using the app will allow you to track usage, view energy statistics, and manage the temperature of your water heater from a distance. Some utility companies may also begin to offer discounts or special rates if you connect your water heater to the “Grid” or to your utility providers.
