This smart control unit is the very hub of a solar water heating system. It has automatic reliable operation, adjustable to a lot of good functions such as fixed temperature, maximum temperature, constant temperature, timing when to turn on the heating and data memory protection, 24 hours hot water setting. The circulation pump regulates the water through the heat exchanger and transfers the heat energy collected by the solar collector to the water storage tank.

Use

The idea of a separate workstation is that it can be placed where you find it most suitable. You can place the solar collectors/collectors anywhere where the sun shines the most and likewise the water tank, it does not have to be together with the solar collectors. Everything can be placed completely separately, so the possibility exists to adapt this facility in the most fashionable as well as in the more sensitive older building with great finesse

Why

Many today are affected by increasingly higher electricity prices, which make it only more and more expensive to use hot water in the amount you are used to. More and more people are therefore looking for solutions that are not affected by electricity consumption as much and then our solar collectors and solar heating systems are a very good alternative!

Please note, in the picture it looks like the expansion tank is supposed to hang on the control unit but in reality the tank has to have its own attachment as it is too heavy when filled with water to just hang from connections!
