What is residential solar water heater


Solar water heaters are heating devices that convert solar energy into heat energy, heating water from low temperature to high temperature to meet the hot water use of people in life and production.

Different types of residential solar water heater


The collector is one of the main components of the solar water heater. From this part, there are three kinds of glass vacuum tube solar water heaters, flat type solar water heaters and ceramic hollow flat type solar water heaters. The glass vacuum tube solar water heater can be subdivided into an all-glass vacuum tube type, a heat tube vacuum tube type, a U-shaped tube vacuum tube type/vacuum tube collecting heat, and a heat storage integrated boring type.


From the structure of solar water heaters, there are compact solar water heaters and split water heaters. The former is to insert the vacuum glass tube directly into the water tank, and the circulation of the heated water is used to raise the temperature of the water in the water tank. The latter separates the collector from the water tank, which can greatly increase the capacity of the solar water heater, and does not use the falling water working mode, thereby expanding the scope of use.


Classified from the pressure of the water tank, it can be divided into pressure-bearing solar water heaters and non-pressure-bearing solar water heaters. The former is that the water is stressful. Generally, it is a top-water type work, and it is not necessary to use a pressurized water tank. The latter is exploited to take advantage of the height drop between the roof and the home, creating pressure when using water. Its safety, cost and service life are much more significant than the pressure type.


There are also three types according to the direction of water flow, which can be divided into three types, namely, circulating, direct current and integral solar water heaters. Different classifications have different types of water heaters. When users choose and use them, they should also choose the most satisfactory solar water heaters from their own habits and structural characteristics of the buildings.

4. Replace the water ball valve.

5. Clean the vacuum tube.

6. Wipe the vacuum tube and the surface of the poly grating.


  • For the problem of dissatisfaction with water.

1. Find broken pipe fittings and replace them with new ones that are not damaged.

2. A booster pump can be added to make the water flow smooth and ensure sufficient water supply.

3. Reconnect or replace the water supply pipe.
