Solar water heaters use sunlight to heat stored water. The water is already heated during use, so the same pipeline can be used for incoming and outgoing water.
Daily maintenance:
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When you use it for the first time, you can open the. faucet to remove debris first.
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 be cleaned when it rains. Keeping the water heater surface clean can get higher heat. effectiveness of the collect.
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. smooth exit.
6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can also use a hair dryer to blow on the water line, or wrap a towel around the water line and then slowly pour warm water over it. Don't cook it in the fire, don't hit its the water pipe and do not scald it with boiling water, because. this will cause the pipe to burst. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
7. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. Users can also do some disinfection work themselves, such as purchasing chlorine-containing disinfectants and adding them. At the water. Pour it into your mouth, soak it for a while, and then release it, which can achieve a certain disinfection and sterilization effect.
8. Solar water heaters need to be cleaned inside the vacuum tube every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect.
9. If the solar water heaterre is equipped with special instruments, please pay attention to lightning protection and electrical protection. Do not take a shower and unplug the electric heater during lightning.
What is the principle of a pipe for upstream and downstream water in a solar water heater?
My simple method is to use a hose to add an auxiliary water tank to the roof. Install a tee at the outlet of the auxiliary water tank. Install a check valve on both sides of the tee. The other port is connected to the solar water inlet on your original. Add a tee to the solar pipe and it should be close to the auxiliary water tank. One side connects the water inlet of the auxiliary water tank and the other side is one way. valve at the front. This way, after each shower you turn on the water supply faucet and it will automatically turn off when the water supply is full. When you get home and preTake a shower, turn off the water supply and wait until everyone has done so. wash finished. Then you can fill the water without looking at it, because there is a float in the auxiliary water tank on the roof. Also pay attention to the auxiliary water tank to exceed the height of solar power. p>
should be The ground water pumped by the water pump returns to the ground after being sent to the water heater, resulting in no water in the solar water heater. If there is a valve at the outlet of the water pump, it can be closed. no valve, there should be a check valve in the water pump suction pipe or inside, maybe there is a problem with the check valve (or valve at the outlet of the water pump).
Water supply: tap water valve. After opening the valve, water flows into the water storage tank of the solar water heater due to pressure and est heated by the solar water heater when the water is filled. there is a pipe and water is overflowing. In this way, it can be determined that the water storage tank of the solar water heater is full, so the water tap of the tap for water supply is closed. From then on, the valve remains closed until the next water supply.
Water supply: Heated tap water is stored in the water heater storage tank. When the bathroom sprays or the hot water valve is opened, the hot water flows through the previous water pipe due to gravity and is discharged. made available to us.

Methods to prevent damage to solar water heaters:< /p >< p>Most electric heating tubes on the market are only equipped with simple thermostats and do not have the function of truly preventing dry heating of the system.
At the same time, most solar water heaters are installed on exterior roofs. This type of extensive management and differences in management skills, coupled with the fact that some manufacturers of electric heating pipes "can prevent dry burning" of their "deceptive" products have caused serious risks of accidents in heaters. -solar water since the installation of electric heating pipes. ?
To solve the problem of "dry burning" of electric heating pipes, in addition to choosing a reliable supplier, you also need to add water to the solar water heater tank in winter when solar energy is not used much. According to Data shows that when there is no water in the water tank and the solar vacuum tube is exposed to sunlight, the temperature inside the tube can reach about 2500°C and it is easy for the tube to explode.
The sound pipest exposed outside in winter. When the weather is very cold, the inside of the pipes freeze and water cannot be delivered. To solve this problem, simply roll up a thick layer of sponge. the water tank pipe or solar pipe, which can effectively prevent water from rising, resulting in empty pipes and pipe explosions.
Secondly, it is also important to check whether the leak protection device is working properly. Additionally, if possible, the water tank should be cleaned at regular intervals. Overall, whether it is an electric heating tube for solar water heater or an electric heating tube for other liquids, it cannot be separated from the liquid and burned dry, otherwise the internal temperature of the electric heating tube will be too high. and the electric heating tube will burn, causing safety hazards.
