Solar Geysers can help you save money as the heating up of a geyser accounts for a good chunk of a home’s energy use, on average about 40% – 60% of your electricity account is contributed to your geyser.
Solar Geysers – Difference between High Pressure and Low Pressure
High pressure solar geyser means that the water in the tank are under high pressure, it’s equal to the pressure of tap water. High pressure solar geysers are designed for on-grid water supply (municipality). Anything over 200kpa is considered high pressure, however 400kpa is ideally what you would want to running your hot water pressure at. The water pressure at the hot water tap will be the same as the pressure from your cold water tap, provided the pipes are of equal diameter.
Low pressure solar geyser means that if water in the tank is under low pressure, and is equal to the gravity of the water. Low pressure solar geysers have a pressure rating of no more than 100kpa of pressure. Low pressure systems are typically used in rural areas and farms, where municipal water supply is not available.
