The solar water heater indicates that it is heating but the temperature does not rise

Introduction The solar water heater indicates that it is heating but the temperature does not increase. If the solar water heater indicates that it is heating but the temperature does not increase, it means that the collector of the water heater is faulty and damaged.

The solar water heater indicates that it is heating but the temperature does not rise

If the solar water heater shows heating but the temperature does not increase, it means that the water heater collector is faulty and damaged. Users need to find professional maintenance personnel to replace the collector with one. new.

The function of the solar water heater collector is equivalent to that of the electric heating pipe of the electric water heater. Unlike electric water heaters and gas water heaters, solar water heaters use radiant heat from the sun. the heating time can only be when the sun's irradiation reaches a certain value.

The most common is the all-glass evacuated solar collector tube. The structure is divided into an outer tube and an inner tube, and the outer wall of the inner tube is covered with a selective absorption coating. The heat collector panel of a flat collector is covered with a heat-absorbing film tel as black chrome, and a metal tube is welded to the heat collecting plate. The cost of a flat sensor is slightly higher than that. of an evacuated tube collector, especially for balcony-type solar water heaters in high-rise residential buildings, have unique advantages.

All-glass solar collector vacuum tubes are generally made of extra hard high borosilicate 3.3 glass, and the selective heat absorption film adopts selective sub-spray coating process. empty.

Precautions for using solar water heaters:

1. radiators, there may be a smell of dust or oil in the water line. When you use it for the first time, you can first open the tap to eliminatetrash.

2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.

3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can clean itself when it rains and keep the surface of the water heater clean.

4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.

5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smoothr water.

What should I do if the temperature solar water heating is not high on a sunny day? What should I do if the temperature still does not exceed 51 degrees?

1. It could be a pipe problem, but normal conditions are the same. 2. You can fill it with water and wait 2-3 days without using hot water to see if it is reached and the solar exhaust releases hot steam. 3. It is also possible that personnel have adjusted the temperature sensing probe or the sensor is inaccurate. Use a mercury thermometer to calibrate it.

Why is the temperature of the solar water heater not high and the water is no longer hot after two years of use?

There are many possibilities for this problem. I don't know if your temperature displayure remains unchanged or lit If the temperature drops below 51 degrees, there is still a problem with the temperature sensor. It is also possible that the heat collecting surface is too dirty or there is too much scale in the vacuum tube, which affects the lighting effect. In this case, you can clean the surface and remove the vacuum tube to clean the inside, but. it's unlikely. If the temperature really cannot rise, then the heat collection effect of the water heater is too low. Whether it is a vacuum tube or a flat panel solar water heater, there may not be much difference to the naked eye, but the actual collection efficiency heat is very different. Of course, water tanks, pipe insulation, etc. are also very different, which greatly affects the water temperature, especially heat dissipation at night. If this is the reason, there is no good way to fix itrepair, except replacement. Therefore, you should choose carefully when purchasing and choose products whose quality is guaranteed.

Hello, we are from the manufacturer Heinard Solar Energy. Whether the water temperature in the solar water tank is high or not mainly depends on the following reasons:

① There is a water heater. in front of the solar vacuum tube The shield blocks the sunlight and the vacuum tube cannot absorb the sunlight;

②The direction and angle of the solar energy are incorrect. The correct direction should be south, and the tilt angle of the collector should be close to the local latitude angle;

③ The water tank is not well insulated, and the insulation performance of the water tank needs to be tested (measure the amount of water cooling). tank overnight);

④ Hot water pipes and cold water pipes are connected in series tor allow hot water to flow from the cold water line, check the pipe, and install a check valve on the main pipe; prevent loss of hot water;

⑤ Check the absorption rate of the vacuum tube;

⑥ Check whether there is too much scale in the vacuum tube, which affects the heat absorption effect; vacuum tube;

⑦ There is a lot of dust on the vacuum tube, so the vacuum tube needs to be cleaned.
