Electric Heat Pump Hot Water System

This hot water then circulates through a pipe to the home s storage water heater tank.

Electric heat pump hot water system.

For water heating you can add a desuperheater to a geothermal heat pump system. Integrated with the tank and compressor combined. Unlike conventional electric resistive systems hot water heat pumps merely move heat from one place air to another water. Heat pumps use electricity but not in the traditional form of electrically heated coils that warm a room.

A fan at the top of the hybrid electric heat pump tank water heater pulls air from the surrounding space through an evaporator. It transfers the heat in the air outside of the unit to the water stored inside the heater through a heat exchange system. There are 2 main types. On average a conventional electric system costs 635 more in energy bills per year.

Like your air conditioner and refrigerator a hot water heat pump pulls heat out of the surrounding air. How heat pump water heaters works. They use no energy to create new heat. It then uses electricity to move that ambient heat into the water tank.

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. These systems use a refrigeration cycle to extract heat from the air to heat the water. 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.

Almost 10 000 savings are far more than enough to repay any price difference between an average hot water system and an efficient one. A fan draws in air containing heat energy across the evaporator the evaporator turns the liquid refrigerant into a gas the compressor pressurises the refrigerant into a hot gas. A heat pump uses renewable energy to heat your water without the need for solar panels. A heat pump is a little like a reverse refrigerator.

Heat pump water heaters are highly efficient and use 30 of the energy of a conventional electric hot water system. A desuperheater is a small auxiliary heat exchanger that uses superheated gases from the heat pump s compressor to heat water. Desuperheaters are also available for tankless or. Therefore these systems are also referred to as air source heat pumps.

The refrigerant runs through a compressor which raises the temperature and pressure. 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.
