Stiebel Eltron Accelera Heat Pump Water Heater

A heat pump water heater is not a new concept. Stiebel Eltron Accelera 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. Plus, payback can be as little as 2 years!

    How a Heat Pump Works

    • The heat pump system contains a fan that forces air through an evaporator (1). The evaporator contains a liquid refrigerant. When this refrigerant evaporates, it extracts heat from the ambient air.
    • The now warm gaseous refrigerant passes through the compressor (2) which increases its pressure. As the pressure increases, the temperature of the refrigerant rises. The refrigerant turns back into a liquid which is now hot.
    • The hot refrigerant then passes through the condenser (3), which is wrapped around the water tank, transferring its heat to the water.
    • The refrigerant which is now cool then passes through an expansion valve (4), where it goes back into a gaseous state and the process begins anew.
