How to maintain the solar water heater for a long time in summer?

When the solar water heater is not used for a long time, the vacuum collector tube should be shielded and removed when it is used again. You can also remove the vacuum collector tube first, but this method cannot be removed by yourself, and you need to contact the professional of the manufacturer for assistance.

The temperature rises sharply in summer, and the solar water heater at high temperature needs more maintenance. Otherwise, improper use in hot weather will reduce its service life. Here are some things you need to know:

Scientific selection of water supply time

Two hours before sunrise in the morning or after sunset in the evening.

Solar water heaters need to supply water regularly, but it is forbidden to supply water when the weather is extremely hot and the water temperature is extremely high, and it is also forbidden to add water immediately after the water is used up. Due to the strong light in summer, solar vacuum tubes are exposed to the sun, and the air drying temperature is as high as 270 ~ 400 degrees Celsius. At this time, water supply is easy to cause the vacuum tube to burst.

B. Reasonable adjustment of hot and cold water valves.

First open the cold water valve, adjust the cold water flow properly, and then open the hot water valve to adjust.

In summer, due to the prolonged sunshine time and high temperature, the hot water in solar water heaters often has a high temperature, which can generally reach more than 60 degrees Celsius. However, the distance between the water storage point and the water consumption point of the solar water heater is often long. Because of the high temperature in summer, the water temperature in the water pipe can reach about 35 degrees Celsius.

Therefore, when we turn on the water heater, the normal temperature hot water in the water pipe will be discharged first, and the high temperature hot water will be discharged after one or two minutes. If we are not careful, we may burn our skin.

Clever use of tail water

It can save resources better.

When taking a bath, if the water in the solar water heater has been used up, but people haven't washed it clean, then you can take a few minutes of cold water and use the principle that cold water sinks and hot water floats to push the hot water out of the pipe, so that you can take a bath. If there is still a little hot water in the solar water heater after bathing, you can wash the hot water again after a few minutes of cold water.

D. according to the weather conditions, determine the water quantity.

Satisfactory water temperature can be obtained.

If it is sunny the next day, you can irrigate it; If it is cloudy or cloudy, the upper part of the water tank is filled with water; It rains all day, so keep raw water instead of cold water.

E regular inspection and maintenance of pipelines.

Regularly check the vent to ensure smooth flow, so as to avoid bursting or deflation of the water tank; Solar water heaters with auxiliary electric heating devices pay special attention to water supply to prevent dry burning without water. At the same time, it is also necessary to check whether the thermal insulation layer and anti-ultraviolet tape of solar water pipes are aging and cracked. If the water supply pipe is exposed, it will easily become hard and brittle, crack and leak in the sun.

F. Regularly inspect and maintain pipelines.

In windy weather, pay attention to strengthening the bracket of solar water heater, and be sure to fill the water heater with water to increase stability and prevent accidents.

G long-term non-use of protective measures should be taken.

Shielded vacuum collector tube

In summer, the outdoor temperature is high, the sunshine time is long, and the radiation is strong. If the water heater is not used for a long time, the water in the water tank stays for a long time, which is easy to form scale. If the pressure is too high, the water tank will expand and be damaged.

Therefore, if the solar water heater is not used for a long time, the vacuum collector tube should be shielded when it is used again. You can also remove the vacuum collector tube first, but this method cannot be removed by yourself, and you need to contact the professional of the manufacturer for assistance.

Perform the above operations

Take care of the solar water heater at home.

You can take a bath happily every day!
