If the solar energy cannot heat properly, the solar vacuum heat absorber tube may be broken, or the electric heater may be broken.
The failure of the solar water heater may be due to the sealing ring of the collector tube being damaged. At this point, the collector tube seal ring should be replaced. It is also possible that the weld bead of the solar water heater is not heating. the water tank liner is cracked or the weld point of the heat exchanger bracket is cracked. In this case, the water tank must be replaced.
If the remaining material in the electric heating hole is not clean or the sealing ring is damaged, you should clean the remaining material in the electric heating hole or replace the sealing ring. waterproofing. A broken interior or exterior pipe can also prevent the solar water heater from heating. In this case, thespecific location needs to be checked and repaired.
The weather is bad and the energy from solar radiation is insufficient. The valve is not tight or is damaged. There is an obstruction in front of the vacuum tube that cannot collect heat effectively. Clear the obstruction or choose another installation location.
Normal use methods of solar energy in winter:
First of all, use solar energy devices heating and antifreeze in a scientific way. Generally, solar water heaters are equipped with heating and antifreeze devices. Consumers often use it to defrost pipes when they freeze. This not only delays the use of the solar water heater, but also damages its lifespan. The scientific method is this: pay attention to the weather forecast. When the temperature remains below 0°C, the anti-freeze device must be activatedé to protect the preheating.
Don't worry about power consumption, because as the temperature of the heating tape increases during use, the power decreases and the power consumption is minimal. However, when taking a bath, be sure to unplug and turn off the power supply to avoid accidents caused by loss of thermal balance.
The second is to enter the water depending on the weather conditions. It is necessary to listen to the weather forecast in time. When the temperature is not low (5-7℃), after using water that night, if there is still hot water in the water tank, the solar water heater must be filled. water immediately to reduce water temperature in the water tank and heat loss that night; If the temperature is low, the water should be turned on the next morning to prevent the pipe from freezing at the outlet of the water heater.
If it rains or snows the next day, you can add half a tank of water, or more than half a tank of water according to actual needs, if the water consumption is important, you may want to consider getting started; the electric heating device in the solar water heater.
The third is to turn on the hot water tap to prevent freezing. If the solar water heater is not used for a long time in winter, the water supply tap should be closed and the water in the water heater as well as the upper and lower pipes should be drained to prevent the pipes do not freeze. In sunny weather, the solar water heater can be used normally; When the temperature is below -5°C, it is best to use water from the water heater in small quantities and several times a day.
Especially before going to bed, you can connect a basin of water under the nozzle or faucet, loosen the hot water faucet a littlee and let it drip slowly to keep the water flow in the solar water heater steady and smooth. effectively avoid freezing and blocking of pipes.
