Electric Heat Pump Hot Water System

Across a hot water system s 15 year lifespan that s 9 525 you can save by upgrading to an efficient hot water heat pump.

Electric heat pump hot water system.

They use no energy to create new heat. Therefore these systems are also referred to as air source heat pumps. Units are usually integrated tank and compressor together but can also be split separate tank and compressor. These systems are more efficient than conventional water heaters despite operating using electricity.

Refrigerant in the evaporator absorbs heat from the air. A heat pump system works like a refrigerator using electricity to move heat from a cool space to a warm space making the cool space cooler and the warm space warmer. This hot water then circulates through a pipe to the home s storage water heater tank. Heat pumps use electricity but not in the traditional form of electrically heated coils that warm a room.

Desuperheaters are also available for tankless or. They absorb the heat from the surrounding air and use it to heat your water. A desuperheater is a small auxiliary heat exchanger that uses superheated gases from the heat pump s compressor to heat water. On average a conventional electric system costs 635 more in energy bills per year.

These systems use a refrigeration cycle to extract heat from the air to heat the water. How heat pump water heaters works. Like your air conditioner and refrigerator a hot water heat pump pulls heat out of the surrounding air. There are 2 main types.

The refrigerant runs through a compressor which raises the temperature and pressure. A fan at the top of the hybrid electric heat pump tank water heater pulls air from the surrounding space through an evaporator. A heat pump uses renewable energy to heat your water without the need for solar panels. It then uses electricity to move that ambient heat into the water tank.

A heat pump is a little like a reverse refrigerator. Almost 10 000 savings are far more than enough to repay any price difference between an average hot water system and an efficient one. Unlike conventional electric resistive systems hot water heat pumps merely move heat from one place air to another water. It transfers the heat in the air outside of the unit to the water stored inside the heater through a heat exchange system.

For water heating you can add a desuperheater to a geothermal heat pump system. Integrated with the tank and compressor combined.
