With the air|water heat pump WPL basic, STIEBEL ELTRON now also offers a highly attractive model for the high turnover entry segment of the market. It stands out on account of its performance characteristics that are normally more expensive, such as its outstanding efficiency. The generously sized evaporator, designed for heating applications, makes its contribution to these characteristics, as does the wide fin clearance that improves defrosting. Defrosting by reversing the refrigerant circuit enables the defrost pan to be heated – without electric booster heater. The galvanised, powder-coated casing, made of stove enamelled sheet steel, is perfectly suited to installation outdoors.
