The solar water heater is 32 degrees all day and the water temperature is 53 degrees.

It depends on the duration of solar irradiation and the basic temperature of the water tank. Under normal circumstances, the temperature is still the same after a continuous day, that is, the heat preservation effect of the water tank is poor and the heat absorption efficiency of the vacuum tube is poor, but if the actual water temperature is not the case, the water level probe is faulty!

"Dr. Sun" solar energy and Sancang solar energy (without water level sensing probe and electromagnetic valve) are recommended, which can quickly heat and utilize hot water in rainy weather, greatly reducing the after-sales rate, saving time and electricity. Compared with ordinary single-room solar energy, this mode only takes 20-30 minutes to heat without the sun, while single-room solar energy takes 2-3 hours!
