Apollo Technology offers you an Apollo 150L High-pressure solar geyser
With our Apollo 150L high-pressure solar geysers, circulation of water happens through natural convection. Therefore, our Apollo high-pressure solar geysers use thermosiphoning. Cold water in this solar geyser pushes the warm water up into the tank. All our Apollo 150 Liter integrated solar geysers use vacuum tubes for the radiation of the sun to heat the water. Our Apollo 150 Liter integrated high-pressure solar geyser has no maintenance required if installed correctly by our qualified solar geyser installers. This is because the Apollo 150 Liter integrated high-pressure solar geyser has no moving parts which can require repairs. An electrical element is also used which only switches on to heat the water when it is really necessary.
