A water-source heat pump water heater, also known as a geothermal heat pump water heater, uses a heat pump to transfer heat from water to heat the water in the storage tank. This type of water heater is highly efficient and can be up to three times more energy efficient than traditional electric resistance water heaters.

Water-source heat pump water heaters are suitable for both residential and commercial applications and they can work in all weather conditions. They are also relatively easy to install and maintain. They are ideal for places where the cost of electricity is high or where natural gas is not available. They use electricity to run but they extract heat from the water so they are more energy efficient than traditional electric water heaters. They are also environmentally friendly, as they don’t produce greenhouse gas emissions. These systems are typically used in areas where there is a ready supply of ground water or surface water, such as lakes or rivers.
