Ideally suited for hot water and space heating – the combi storage tank

The tank-in-tank WPKR combination storage tank line elegantly unites two solar thermal functionalities: whilst securing the domestic hot water supply, it also covers up to 30% of space heating requirements in well-insulated buildings. The domestic hot water is stored in the enameled inner tank, with the outer tank providing the space heating water.
