Normally, we all know that solar water level has 4 levels: 20%, 50%, 80% and 100%. These 4 gears are adjusted as 4 points on the water level probe. Level 100 is at the top. When water first floods the 100 level sensor, it will turn on (actually the whole water tank is not completely filled at that time. When we use hot water, the water level drops to). 100%, the 100% water level light will turn off. There is a gap between the 100% and 80% points, where a lot of water can be put. So it's normal. This is the case for all solar energy.
Solar water heater water level problem
Introduction The water level problem of solar water heaters is normal. We all know that solar water level has 4 levels: 20%, 50%, 80% and 100%. These 4 gears are used to detect water levels.
