The new building is renovated and solar energy is also newly installed. All the solar water heaters we buy now have an automatic water supply. It is best to use a fully automatic self-priming pump. Install a fully automatic self-priming pump and solenoid valve where solar water is added. When the solar meter indicates that water is added, power is simultaneously supplied to the solenoid valve. The solenoid valve opens, the pump starts and. water is added to the solar water heater. When the water is full, the meter stops adding water, the synchronous solenoid valve is closed, and the fully automatic self-priming pump continues to work. After about 5 seconds, the water line pressure reaches. the set pressure and stops working. When the solar adds water again, the solenoid valve opens, the pressure in the coThe water flow decreases and the fully automatic self-priming pump restarts. The process is like this. It is best to use a 125W fully automatic self-priming pump, which is enough for you. Pressure is applied only between the pump and solenoid valve, and there will be no pressure elsewhere. Don't hesitate to use it. The self-priming pump you mentioned above is the type of pump I mentioned, so you can use it without any problems. If your solar water heater is outdated and does not have an automatic water supply function, you can replace it with a new set of meters. The price of the meter is about 150 yuan, which includes solenoid valves and sensors. This way you will be able to use it completely automatically without human intervention. I hope my answer is helpful to you.
There is no problem with tap water providing water under its own pressure.Your pump is just for auxiliary pressure. This pump is sufficient. energy. This has always been the case for work. Moreover, it will not have any side effects on the solar water heater. The solar water heater is a normal pressure device. When water is added to solar power, it does not generate pressure and the pipe does not burst at all. That's how you use it, that's right. What I'm talking about is simply replacing your valve with a solenoid valve to make it fully automatic. Yours is manual, that's the big difference. Nothing else
