Electric Heat Pump Hot Water System

On average a conventional electric system costs 635 more in energy bills per year.

Electric heat pump hot water system.

How heat pump water heaters works. A heat pump is a little like a reverse refrigerator. 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.

A fan at the top of the hybrid electric heat pump tank water heater pulls air from the surrounding space through an evaporator. This hot water then circulates through a pipe to the home s storage water heater tank. The refrigerant runs through a compressor which raises the temperature and pressure. These systems use a refrigeration cycle to extract heat from the air to heat the water.

Almost 10 000 savings are far more than enough to repay any price difference between an average hot water system and an efficient one. They absorb the heat from the surrounding air and use it to heat your water. For water heating you can add a desuperheater to a geothermal heat pump system. Integrated with the tank and compressor combined.

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. 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.

These systems are more efficient than conventional water heaters despite operating using electricity. Therefore these systems are also referred to as air source heat pumps. Heat pump water heaters are highly efficient and use 30 of the energy of a conventional electric hot water system. 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.

It transfers the heat in the air outside of the unit to the water stored inside the heater through a heat exchange system. They use no energy to create new heat. Unlike conventional electric resistive systems hot water heat pumps merely move heat from one place air to another water. A heat pump uses renewable energy to heat your water without the need for solar panels.

Refrigerant in the evaporator absorbs heat from the air. 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.
