The beauty of heat pump water heating technology is that the amount of electrical energy needed to create hot water is greatly reduced compared to a conventional electric tank type water heater. The efficiency of the unit goes up with increasing ambient air temperatures. This ground breaking efficiency redefines what a water heater is capable of.

In a warm climate, the unit can either be placed in the garage where it takes heat from the ambient air, or inside the house, where it helps with the air conditioning load. In a cooler climate, the unit is typically placed in the basement where it also acts as a dehumidifier. You get hot water at a discount and a dry basement as well.

If the heat pump that is built into the unit alone cannot keep up with the hot water demand then an electric backup element with 1.7 kW loading will automatically activate.

Simple Innovation from Germany

Heat pumps have been around for decades, but a heat pump water heater is a new concept. The Accelera® 200E works like an air conditioner but instead of dumping the heat outdoors, it puts it into the water.

The heat pump system contains a fan that forces air through an evaporator. The evaporator contains a liquid refrigerant. This refrigerant evaporates and extracts heat from the ambient air. The now warm gaseous refrigerant is then compressed by the compressor which is driven by an electric motor. As it goes through the compressor the pressure and temperature rise. The refrigerant turns back into a liquid which is now hot. The refrigerant then passes through the condenser, which in this case is wrapped around the water tank. The hot refrigerant loses its heat which goes into the DHW. The now cooler refrigerant then passes through an expansion valve where it goes back into a gaseous state and the process begins anew.
