Solar water heater how to connect the water pipe schematic

1, single-pipe water installation schematic

The following figure for the installation of manual control, if the automatic control, "water valve" to replace the "solenoid valve" can be, pay attention to the solenoid valve in and out of the water direction.

2, two-pipe water installation diagram

The following figure for the installation of manual control, if automatic control, "water valve" can be replaced with "solenoid valve", pay attention to the solenoid valve in and out of the water direction.

Extended information

Solar water heater is the first cold water into the thermal storage tank, and then through the collector will be transported to the heat preservation tank. The thermal storage tank is connected to the indoor cold and hot water piping so that the whole system forms a closed loop. Well-designed and properly connected solar pipes are crucial to whether a solar system can work optimally. The solar energy pipeline must do the heat preservation treatment, the cold northern regions need to lay in the pipeline outside the wall of the heat tape, in order to ensure that the user in the cold winter can also use the solar energy hot water.

Domestic solar water heaters usually work on a natural cycle, with no external power. Vacuum tube solar water heaters are plug-in structures, with hot water powered by gravity. Flat-plate solar water heaters are powered by the pressure of tap water (called top water). And centralized solar heating systems all use pump circulation. Since solar water heaters do not have a large heat collection area, pipeline circulation is generally not used, taking into account the heat loss.
