PS 185 Pressurized Solar Water Heater

Pressurized solar water heater assembly

Pressurized solar water heater with integrated stainless steel tank, designed for producing domestic hot water when air temperatures are above 0°.

Available in versions with terrace frame or slope roof frame.

The solar water tank is made of high quality stainless steel and has a capacity of 185 liters. The tank’s maximum working pressure is 6 bar and several solar water heaters can be connected in a series. The water tank can be connected directly to the public network or to a private pump station.

The pressurized solar water heater doesn’t need to be installed high above the consumer level and it even can be installed on the ground.

The vacuum tubes are equipped with copper heat-pipes and do not contain water. The vacuum tubes solar water heaters offer the highest performance of harvesting the solar energy. The vacuum tubes are made of borosilicat glass which is coated on the inner side with 3 absorption layers which amplify the effect of solar irradiation. The inner vacuum ensure that harvested energy is transferred to the water tank with minimum heat-loss. The cylindrical shaped tubes ensures a high performance all day long, even in partly cloudy skies.
