The Accelera 220E, boasts increased efficiency, with an even higher Energy Star rating! A heat pump water heater is not a new concept. The Accelera® 220E works like an air conditioner but instead of dumping the heat outdoors, it puts it into the water. 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 groundbreaking efficiency redefines what a water heater is capable of.

Stiebel Eltron has been the world leader in the development of advanced water heating and energy-saving technology since 1924.
