Non-pressurized Solar Heater

Non-pressurized Solar Heater

Non-pressurized solar heater for domestic use make the water is heated by means of vacuum tubes which take advantage of solar radiation. Cold water is heavy, and when heated increases the density reason why it rises to the top of the storage tank which has a thermal layer of usually 50mm to keep the water warm.

And our this non-pressurized solar heater has an auxiliary tank which aims to keep the main tank filled with water.  When opening the hot water stopcocks, the pressure depends on the height where the heater is installed, as it is attracted by gravity.  Our non-pressurized solar heater is recommended to install 2 to 3 meters high in relation to the shower.
