Specific interview methods are as follows:
1. Disconnect the power supply and drain the water to prevent sewer pipes from freezing in winter.
2. Carry out cleaning work to keep the water heater clean and tidy.
3. Cover the vacuum tube so it no longer absorbs heat, or simply remove the tubes.
4. Additionally, the water heater should be covered to prevent excessive dust.
What is the principle of solar water heating?
1. Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature.
2. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used.
3. Domestic solar tube water heatersou vacuum are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes, which use hot water. to float and cold water to sink. According to the principle, the water will produce microcirculation to obtain the required hot water.
The solar water heater is a device that uses energy from the sun to heat water from low high temperature temperature. . Thermal energy products. The core part of the solar water heater is made of coated glass tubes and is easily broken, so everyone should pay attention to the following maintenance knowledge when installing and using it.
1. Solar water heaters are installed outdoors, so the water heater and roof must be installed securely to withstandto strong winds.
2. In winter in the north, water heater pipes must be insulated and frost-proof to prevent water pipes from freezing and cracking.
3. The water heater must be designed and installed by the manufacturer or a professional installation team.
4. Most water tanks are designed as pressure-free structures. The overflow port and exhaust port at the top of the water tank must not be blocked, otherwise the water tank will break due to excess water. pressure in the water tank. If the tap water pressure is too high, turn off the tap when filling the water, otherwise the water tank will burst because you will not have time to empty it.
5. The air drying temperature of the vacuum tube can reach more than 200°C. Do not add water for the first time or when you are unsure whether there is water in the tube. Water under the scorching sun, otherwise theglass tube will break. It is best to turn on the water early in the morning or evening or after blocking the collector for an hour.
6. The water temperature of the vacuum tube water heater can reach 70℃~90℃, and the maximum temperature of the flat water heater can reach 60℃~70℃. When bathing, you need to adjust it. hot and cold water. Put cold water first then hot water to avoid burns.
7. Check once a year if the water tank is leaking, if the parts are aging, if the collector is damaged, if the bracket is rusty, etc. If problems are found, they should be replaced. and repaired on time. It is best to have them installed by professional maintenance personnel.
