Stiebel Eltron Accelera 300

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 Accelera's compressor and fan consume only 1kWh of electricity to generate the heat equivalent of 3 – 5kWh. The efficiency of the unit goes up with increasing ambient air temperatures. This ground breaking efficiency redefines what a water heater is capable of.

Heat pumps have been around for decades, but a heat pump water heater is a new concept. The Accelera® 300 works like an air conditioner but instead of dumping the heat outdoors, it puts it into the water.

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 cannot keep up with the hot water demand, an electric backup element with 1.7 kW loading will automatically activate.
