Thermosyphon system Sunstar SS-HE 220L, inox

The water container with a built-in coil is in fact an instantaneous heat exchanger. The coil is connected to the water supply network. Water passing through it is heated by the water in the container and reaches the shower mixer at mains pressure. After the initial filling of the container, the water in it decreases only through evaporation.

The auxiliary tank is optional, and a tap for periodic topping-up can be used instead. The coil fittings are located on the side, as is the auxiliary electric heater. It can be used all year round. If there is an electric water heater in the household, it is recommended to connect them into one system so that in the winter months water from the solar collector flows into the electric water heater.

The advantages of this type of solar system are that it eliminates the need for a height difference and can be installed in any convenient place.
