HST Series Two Coils Water Tank

Keram HST Series hot water tanks are developed especially for the increasingly popular heat pump. The large heating surface of the heating coil and its sophisticated diabolo-shape enable a very efficient hot water production, which guarantees a quick reheat time and a high hot water performance. The high-quality insulation reduces heat loss, which minimizes the costs for a high hot water performance. The two coils structure inside makes the water tank can be connected both heat pump and solar. A combination of a more efficient system saves more energy consumption.
