Design Solar Geyser
Design Solar Geysers, also called "Compact Systems", allow us to save on average throughout the year 80% of the energy consumption we use to heat domestic hot water.
Its operation is as follows, cold water enters the water tank through the small auxiliary tank, with floating. First the evacuated tubes are filled and then the water heater. When solar radiation begins to affect the tubes, 80% approx. It is absorbed by them in the form of heat and transmitted to water which raises its temperature. The hot water goes up to the tank and the cold water from the tank goes down the pipes where it is also heated, and the process is repeated until all the water in the tank is at a high temperature. This process is called Thermosiphon, or circulation by density difference.
This is called a NO pressurized system, to be differentiated with other systems since it does not support very high water pressures unlike the others (its maximum working pressure is: 0.6 bar) and in turn is more economical due to its way of manufacturing. In contrast, pressurized systems withstand higher water pressures, where their maximum working pressure is: 6 bar.
