Low Pressure Solar Heater

- May 12, 2020-

The operation principle of low pressure solar heater is based on the phenomenon of heating by natural convection of the water inside the vacuum tubes (the thermosiphon principle). Through vacuum tubes, the heating water will circulate, after which it will rise in the tank, and the cold water from the tank will descend into the glass vacuum tubes, replacing the hot one that has climbed.


Low pressure solar heater will have to be mounted at a higher height than the highest consumer. The final water pressure is given only by the height at which it will be mounted (the principle of gravity).

If you want to mount the low pressure solar heater on the ground, the system can only work with the help of a pressure increase pump, which you can also get from us.


Low pressure solar heater is the simplest model, and optionally it can be equipped with electrical resistance, for long periods without sun.
