Electric Heat Pump Hot Water System

For water heating you can add a desuperheater to a geothermal heat pump system.

Electric heat pump hot water system.

This hot water then circulates through a pipe to the home s storage water heater tank. On average a conventional electric system costs 635 more in energy bills per year. Almost 10 000 savings are far more than enough to repay any price difference between an average hot water system and an efficient one. The refrigerant runs through a compressor which raises the temperature and pressure.

These systems are more efficient than conventional water heaters despite operating using electricity. They absorb the heat from the surrounding air and use it to heat your water. Unlike conventional electric resistive systems hot water heat pumps merely move heat from one place air to another water. Heat pump water heaters are highly efficient and use 30 of the energy of a conventional electric hot water system.

Refrigerant in the evaporator absorbs heat from the air. Integrated with the tank and compressor combined. 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. A fan at the top of the hybrid electric heat pump tank water heater pulls air from the surrounding space through an evaporator.

Units are usually integrated tank and compressor together but can also be split separate tank and compressor. They use no energy to create new heat. 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.

It transfers the heat in the air outside of the unit to the water stored inside the heater through a heat exchange system. A heat pump is a little like a reverse refrigerator. Like your air conditioner and refrigerator a hot water heat pump pulls heat out of the surrounding air. It then uses electricity to move that ambient heat into the water tank.

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. Desuperheaters are also available for tankless or. 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.

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. Heat pumps use electricity but not in the traditional form of electrically heated coils that warm a room.
