Why is the water inlet of the hot water circulation pump not a return pipe interface and a cold wate

Introduction Why is the water inlet of the hot water circulation pump not a return pipe interface and a cold water pipe inlet? Since it is a hot water circulation pump, it must achieve the circulation of a certain part of the water.

Why is the water inlet of the hot water circulation pump not a return pipe interface and a cold wate

As it is

a hot water circulation pump

, it must carry out a certain part of

the circulation of water

. It is not used to fill tap water.

So you cannot connect the water pipe at one end.

For water heaters, the tap water supply has a certain pressure. Daily water heaters do not need to install a water pump in the tap water supply line. And even if installed, the water pump is a pressure booster pump and not a hot water circulation pump.

The conventional solar thermostatic water mixer does not have a one-way check valve at the hot and cold water inlet. If no water is used, when the pressure on one side of hot and cold water is. significantly greater than the pressure on the other side, the pressure will flow to the side with lower pressure, resulting in fiwater lage. Since general solar water heaters do not bear pressure, their pressure is generally lower than the pressure of tap water (cold water), so the water will be supplied by solar energy. We recommend the Jingming brand thermostatic water mixer, produced by Beijing Mingjianye. It has a built-in one-way check valve to prevent water from leaking. The performance is also good, you can try it.
