How to increase the hot water outlet pressure of non-pressure solar water heaters?

【Abstract】：

When the solar energy market becomes more and more widespread, more and more people use solar water heaters worldwide, and the demand for solar water heaters is also increasing. At the same time, an affordable non-pressure solar water heater is loved by many families. The one-piece non-pressure solar water heater uses an open non-pressure water tank.

Therefore, the water outlet pressure is equal to the height difference between the installation height of the water heater and the water outlet of the user end; if you want to get a better comfort experience when taking a bath and increase the water outlet pressure, you can use the following methods:

【Main body】：

1. When the non-pressure solar water heater has not been installed, the method of increasing the height difference between the hot water outlet and the water tank can be adopted.

Non-pressurized solar water heaters rely on gravity to produce hot water.

The water outlet pressure is determined by the installation height of the solar water tank and the height difference between the water outlet. The installation height of the water tank is higher than the water end, and the greater the height difference, the greater the water outlet pressure.

Therefore, it is best to pay attention during installation to increase the height difference between the hot water outlet and the water tank. The greater the height difference, the greater the hot water outlet pressure.

2. When the non-pressure solar water heater has been installed, a booster pump can be added to the hot water outlet pipe.

The booster pump is composed of pump + water flow switch + power supply. When the faucet is turned on, the water flow switch immediately starts the switch, the power is turned on, and the water pump starts to run to increase the water flow pressure.

Therefore, install the booster pump in the hot water outlet pipe of the non-pressure solar water heater to increase the water pressure and make it more comfortable to use.
