Solar Energy Combined System SECS – Heating and SHW


A solar energy combined system produces hot water from the sun for space heating and domestic hot water.

In the systems proposed by SYRIUS, the storage tank is a «tank in tank» type: the domestic hot water tank is inside the storage tank for the space heating water. The solar collectors heat the main tank with the exchanger. The domestic hot water storage tank will be heated and kept at a constant temperature in the main storage tank.

The system is composed with a regulator which control solar pump and the space heating pumps. Back- up energy can be provided by a back-up boiler (gas, oil, wood), a heat pump or an electric element.
