Solar water heater manufacturer Taian analyzes the problems of water heater use and methods to extend its service life:
Why is the water pressure of solar water heaters low?
The water flow from the nozzle of the solar water heater is very low, why can't it spray? I think many users with low floors will usually face such a situation. The water flow from the solar water heater nozzle is very small and cannot be sprayed.
Today I will give you a simple analysis. Phenomenon: The water flow from the nozzle of the solar water heater is not large. Reasons:
1. The height of the solar energy is not enough, and the natural pressure formed is insufficient.
2. The water pressure in the water pipe is too low and the pressure difference between the water heater tankand the nozzle is very weak, so the pressure is low once the water is mixed.
3. The nozzle has few holes or is partially blocked by impurities.
Processing method:
1. Use a booster pump and turn it on when the solar outlet is used more.
2. Wait for the water pressure to increase.
3. Replace the nozzle with a large volume of water spray or clean the nozzle.
When the water drop is small, the water outlet pressure is low. A fall of 10 meters is approximately equivalent to 1 kilogram of pressure. Comfortable swimming requires a drop of more than 15 meters. On the top floor, install a solar water heater, the distance between the solar water outlet and the shower is only about 3-4 meters, so it feels like the water is not flowing. When the drop of the solar water heater falling is small, the water outlet pressure is low. A fall of 10 meters equalis approximately 1 kilogram of pressure. Comfortable swimming requires a drop of more than 15 meters. top floor and install a solar water heater, the distance between the solar water outlet and the distance between showers is large
Solution 1: Add an automatic water booster pump. Disadvantages of the booster pump: its lifespan is generally 3 to 5 years, it is noisy and it requires a reserved space inside, leading to maintenance and inconvenience. Solution 2: Choose a pressurized fresh water solar water heater. The water outlet pressure comes from the tap water pressure (the tap water pressure is generally 1.5-2.5kg, which is equivalent to a drop of 15-25 meters ). ).
Can regular maintenance of solar water heaters extend their lifespan?
Methods that can extend the life of solar water heaters:
1. Remove the growth regularlyer and dirt on the transparent cover of the solar collector and keep the cover clean to ensure proper operation. Higher transmission. Cleaning work should be carried out early in the morning or evening when the sunlight is not strong and the temperature is low to prevent the transparent cover from being broken by cold water.
2. Drain the system regularly to prevent pipeline blockage; and clean the water tank to ensure water quality. When discharging sewage, simply open the sewer valve until clean water flows from the sewer valve while ensuring a normal inflow of water.
3. Pay attention to check whether the transparent cover is damaged, replace it in time.
4. For vacuum tube solar water heaters, always check the vacuum degree of the vacuum tube or whether the inner glass tube is broken when the vacuum tube barium——If the getter en titanium turns black, this indicates that the vacuum level has dropped and the collection tube needs to be replaced.
What preparations should be made before installing the solar water heater project?
In recent years, solar water heater engineering systems have developed rapidly. Hot water is used in schools, hotels, foot baths, etc., and the demand for hot water is relatively large, so hotels are. more suitable for installation. The solar hot water engineering system is, on the one hand, energy-saving and environmentally friendly, and on the other hand, it eliminates the labor and material costs of solar hot water engineering. manual boiling of water. So, what preparations should be made before constructing a solar water heating project?
1. Check the construction conditions of the unit: the size and shape of the heat collection area of the building, the height of the buildingent and the location where the water tank is allowed to be placed (roof, floor). , basement, etc.) are mostly different.
2. User Unit Requirements: Total daily water consumption; whether the user uses it once a day or at any time; required water temperature; actual use: bathing water, bath heating, fish pond; Heating, ambient heating (planting or breeding greenhouse).
3. Location and geographic conditions: Analyze installation conditions based on the user's geographic latitude, lowest ambient temperature in winter, all-season sunlight conditions, and whether there is an obstruction in the direction of the sun. .
4. Conditions for auxiliary energy of the user unit: Determine the use of one or more solutions (electric heating, electric boiler, oil or gas boiler, water source, heat pumpgeothermal heat or air). , etc.) Combined plan.
5. Water Pressure and Voltage of User Units: Understand the water pressure, voltage and power situation of user units.

Yes. According to the “Safe Use Specifications of Solar Water Heaters”, it is known that when the pressure in the pipeline exceeds the specified bearing pressure of the pipeline, the pipe will explode. Therefore, if the rooftop solar water heater blocks the system. water inlet pipe and pressurize the water line, it will explode. A solar water heater is a device that uses energy from the sun to heat water from low temperature to high temperature.
