Solar storage tanks, cylinders for DHW heating
HEWALEX solar storage tanks are designed to be combined with solar collectors and a condensing or conventional boiler, or even with electric heating, to prepare domestic hot water (DHW). The water in the tank is primarily heated by the solar heat exchanger at the bottom of the tank. If the output from the solar system is insufficient, the water can be further heated to the required temperature by the condensing or conventional boiler, or by an electric heating element.
