Electric Heat Pump Hot Water System

Heat pump a much more efficient form of electric storage tank system that works on the same principle as a fridge or air conditioner by extracting heat from the air and using it to heat the water tank.

Electric heat pump hot water system.

They absorb the heat from the surrounding air and use it to heat your water. They use no energy to create new heat. Desuperheaters are also available for tankless or. For water heating you can add a desuperheater to a geothermal heat pump system.

It then uses electricity to move that ambient heat into the water tank. 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. The refrigerant runs through a compressor which raises the temperature and pressure. Heat pumps use electricity but not in the traditional form of electrically heated coils that warm a room.

Like your air conditioner and refrigerator a hot water heat pump pulls heat out of the surrounding air. 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. There are 2 main types.

These systems use a refrigeration cycle to extract heat from the air to heat the water. A heat pump uses renewable energy to heat your water without the need for solar panels. Units are usually integrated tank and compressor together but can also be split separate tank and compressor. Unlike conventional electric resistive systems hot water heat pumps merely move heat from one place air to another water.

Therefore these systems are also referred to as air source heat pumps. These systems are more efficient than conventional water heaters despite operating using electricity. On average a conventional electric system costs 635 more in energy bills per year. 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.

Almost 10 000 savings are far more than enough to repay any price difference between an average hot water system and an efficient one. Integrated with the tank and compressor combined. Refrigerant in the evaporator absorbs heat from the air. This hot water then circulates through a pipe to the home s storage water heater tank.

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. How heat pump water heaters works.
