If the two water valves are opened separately, the hot water faucet will not flow out. Check whether there is a water valve in front of the hot water faucet, and open it if there is one. If there is still no water in the solar energy, open two solar water valves at the same time. At this time, there should be water coming out of the hot water tap. Try to close a water valve. If the hot water faucet does not flow out at this time, the water valve is used for hot water.
After distinguishing the cold water inlet and hot water outlet functions of the two solar water valves, open the cold water inlet valve after each water use, so that when the water overflows with solar energy, close the cold water inlet valve (it only takes 20 minutes without installing automatic water supply equipment), and the hot water valve can be opened all the time, or it can be opened before each water use, and then the hot water faucet is turned on.
Question 2: How to use the solar water heater correctly? If it is not used for a long time, it is recommended to empty the water. At the same time, close the water supply valve and unplug the power supply.
The reason is to prevent icing (including the water pipe part). As for the residual water in the solar water pipe, let it boil with solar energy and evaporate by itself.
Special attention: when it is reused, the water supply must be at night or on cloudy days to prevent the high-temperature heat collector from bursting in cold water.
Question 3: How to use the solar water heater How to use the solar water heater In the process of using the solar water heater, you will find that if you arrange the water supply time and quantity skillfully, you will get twice the result with half the effort. Users who just started using it may not be very clear. After a long time, they will gradually explore the experience and laws. Here we introduce the use skills of several solar water heaters:
A, when taking a shower, if the water in the solar water heater has been used up and people haven't washed it clean, then you can take a few minutes of cold water, and use the principle that cold water sinks and hot water floats to drain the hot water in the vacuum tube, so that you can take a shower.
B, using the principle of A, if there is still a little hot water in the solar water heater after bathing, you can use cold water for a few minutes, and hot water can wash one more person. (Each vacuum tube produces 6.5 liters or 8 liters of hot water)
C. According to the weather forecast, we can get a satisfactory water temperature: if it is sunny, we can fill it with water; if it is cloudy or cloudy, we will fill it with more than half of the water; If it rains, keep the raw water without cold water.
D. If there is still half of 70℃ hot water in the water tank of the water heater after bathing at night, in order to prevent excessive heat loss (the less water, the faster heat loss), the water intake should be determined according to the weather forecast. It will be filled with water in sunny days and 2/3 in rainy days.
E. Function of auxiliary water tank: The auxiliary water tank mainly serves areas with regular water supply and unstable water pressure, and its water storage capacity is between 1/2-3 times that of solar water heaters. It is installed on the roof and used in conjunction with the solar water heater. The main function is to adjust the water temperature by mixing cold water when bathing, and it can also be used as a water storage tank when water is stopped, and can also precipitate impurities in water in areas without running water.
F, cold and hot water adjustment: the water temperature adjustment steps of the solar water heater are as follows: first, open the cold water valve, properly adjust the cold water flow, and then open the hot water valve for adjustment until the required bathing temperature is reached. In addition, the amount of cold water can be determined empirically according to weather conditions. Be careful not to point the nozzle at the human body to avoid scalding.
G. Wind-resistant measures: Because the components of solar water heater are connected reliably, the wind-resistant performance mainly depends on its installation and fixing methods. At present, Huang Ming is fixed by 8# galvanized iron wire and extended expansion bolts, which form a figure of eight before and after, and have good wind resistance. In addition, in coastal areas with strong wind, it is best to change the bracket structure, or remove the backboard and fix it with steel ropes for fixing telephone poles.
H. How to prolong the service life: In order to prolong the service life of solar water heaters, users should pay attention to the following points during use:
1. After the water heater is installed and fixed, non-professionals should not move or disassemble it easily to avoid damaging key components.
2. There should be no sundries around the water heater to eliminate the hidden danger of hitting the vacuum tube.
3, regularly check the vent to ensure smooth, so as to avoid water tank burst or deflation.
When cleaning the vacuum tube regularly, be careful not to touch the tip of the vacuum tube.
5, winter should prevent pipeline frost crack, and ensure the smooth exhaust pipe.
6. Solar water heaters with auxiliary electric heating devices should pay special attention to water supply to prevent dry burning without water.
Question 4: How to use the solar water heater correctly? List of common problems of solar water heaters.
1. How to use a solar water heater without running water?
When solar water heaters are used in areas where there is no running water, water can generally be supplied by water pump, and an auxiliary water tank with the same height as the solar water heater is added to store cold water, so that it can be mixed with cold water when bathing.
Second, what problems should be paid attention to in the use of solar water heaters?
1. Pay attention to the water supply time.
2. Determine the amount of water according to the weather to ensure that the water temperature is appropriate when taking a bath.
3. Regularly check whether the pipes, exhaust holes and other parts of the water heater are working normally.
4. In areas with serious air pollution or windy sand and dry weather, the vacuum tubes should be cleaned regularly.
5. After the water heater is installed. Non-professionals should not easily move, load and unload the whole machine to avoid damaging key components.
Third, how to choose the water heater capacity according to family needs?
Under normal circumstances, each person needs 20-40kg of hot water for bathing, and each vacuum tube can heat 6.5kg of water. The required water heater capacity can be estimated according to the family population and the habit of bathing water consumption.
Fourth, how to judge whether the solar water heater is full?
Generally, solar water heaters are equipped with overflow pipes, and whether the water is full can be judged according to whether the overflow pipes are draining water. In addition, it can be equipped with a water level controller to automatically give an alarm when the water is full.
5. What may cause the water tank to burst and deflate?
It may be because the vent is blocked. When water enters and exits, the internal air cannot be discharged or replenished immediately, resulting in the pressure difference between the inside and outside, which leads to the bursting or deflation of the water tank.
6. What is the relationship between the size of the water tank and the number of vacuum tubes?
General water heaters are designed according to the temperature of hot water needed for bathing. The design water temperature range of Chuangerte solar water heater is 400C~900C, and each tube heats 6.5kg of water.
Seven, vacuum tube solar water heater water should pay attention to what problems?
Because the temperature in the vacuum tube can reach about 250 degrees when it is aired in the air, it is necessary to fill the water tank for the first time without water or before sunrise or half an hour after sunset.
Eight, how to distinguish the advantages and disadvantages of solar water heaters?
Solar water heater is a kind of solar heat utilization, and the whole water heater includes a heat collection part, a heat storage part and a bracket part. The main basis for judging the quality of heat collecting parts is the absorption rate and divergence rate of heat collecting elements, which is related to materials and manufacturing technology. The heat storage element is the warehouse of the water heater, and its quality assurance has two aspects: one is no leakage, and the other is heat preservation. The welding method of the liner is very important, and whether the welding strength and material are anticorrosive is the key to the quality of the liner. In addition, the thermal insulation material determines the thermal insulation performance, and the thickened thermal insulation layer must be used in cold areas. (3) The bracket supports the operation of the main engine to ensure the correct position of the heat collecting element. It needs to have the same life as other parts of the main engine, and requires good strength and corrosion resistance, which can be judged by visual inspection of its material, thickness and surface treatment.
Question 5: How to use the solar water heater controller? See if this works. General controllers are similar.
Instructions for use of microcomputer full intelligent measuring and controlling instrument for solar water heater
At present, the functions and operations of most solar microcomputers are as follows: (Note: I am obliged to scan the instructions of microcomputers for users, and some words may be garbled. Please forgive me)
Features: automatic water supply, constant temperature water supply function, regular water supply, digital color screen display of water temperature and water level, humanized design, water level preset, low water pressure water supply mode, timing control, manual control, automatic overflow prevention, high temperature protection and other main functions. It is more convenient, safer and more practical to use.
I. Main technical indicators
1, power supply: 220VAC, power consumption: >
Question 6: How to use a professional master to install and connect water and electricity and a microcomputer controller. There are no special circumstances, you just use hot water. . It will run automatically.
Question 7: How to use the solar water heater? Electric heating should have the design of electric auxiliary heating, but the power is low, that is, the heating time is quite long.
1500w power is very low.
Ordinary gas water heater, converted into electric energy.
Over 6000w W w.
Wait a little longer.
Question 8: How to use the general solar water heater? When it is filled with water, the temperature will rise by at least 30 degrees in the sun during the day. If you don't use it that day, the water temperature will definitely be 50-60 degrees on a sunny day. Even if the temperature drops on cloudy days or at night, it should be above 40 degrees. You can usually take a bath, let alone take a royal bath. Unless it is cloudy continuously, the number of electric heating is very small. If not, there should be something wrong with the insulation. Please check with the seller or manufacturer.
Question 9: What should I pay attention to when using solar water heaters? 1) The best water supply time is at night or in the morning. In sunny days, the first water supply or water tank is dry for more than 15 minutes, and water supply cannot be carried out during the day, otherwise the vacuum glass tube will burst suddenly or the vacuum tube will scale when it is cold.
2) Regularly check whether the pipes, exhaust holes and other parts of the water heater are working normally.
3) When not in use, the hot water nozzle and water supply valve are all closed. When taking a bath, just open the drain valve, close the water supply valve and adjust the hot and cold water nozzles. When only water is supplied, the water supply valve can be opened.
4) Pay attention to inspection at ordinary times to ensure that there is always water in the water tank. Check the vent regularly to make sure it is unblocked, so as to prevent the water tank from bursting or venting.
5) The overflow port and exhaust port at the top of the confined water tank must not be blocked, otherwise the water tank will rupture due to excessive water pressure in the water tank. If the tap water pressure is too high, the opening of the valve should be smaller when adding water, so as to avoid bursting the water tank because it is too late to drain water.
6) The vent hole of the unpressurized water tank should be kept clear, and the vent should not be blocked. It is strictly forbidden to install or modify any device without permission to avoid damage to the water tank due to poor exhaust.
7) When the heat collector is not used for a long time, it should be covered with opaque materials to prevent the water tank from overheating and the sealing material from aging.
8) Check once a year whether the water tank leaks, whether the parts are aging, whether the heat collector is damaged, whether the bracket is rusted, etc. Timely replacement or maintenance problems, preferably by installation and maintenance personnel.
9) After the installation is completed, the water supply must be carried out for the first time in the morning or evening, because the temperature of the vacuum tube is very high due to the dry air, and suddenly cold water will cause the tube to explode. Keep a certain amount of water in the water tank to avoid air drying affecting the life of the vacuum tube.
10) Clean the vacuum tube regularly in areas with serious air pollution or areas with heavy wind and sand.
1 1)。 Non-professionals should not easily move, load and unload the whole machine to avoid damaging key components.
12) the water heater with auxiliary electric heating should be powered off when in use, and it is forbidden to take a bath with electricity.
13) When it is not used in thunderstorm weather or for a long time, the auxiliary electric heating plug must be unplugged.
14) the water temperature of vacuum tube solar water heater can reach 70-90 degrees, and the flat plate can reach 60-70 degrees. When using, test the water by hand to avoid scalding.
15) In order to avoid accidents, if there is an electric heating device, a leakage protector must be installed. It is forbidden to use the plug of the leakage protector as a switch, and do not unplug it frequently.
16) It is forbidden to operate the electrical parts with wet hands.
17) The water in the collector can't be completely discharged, which is easy to breed bacteria, so it's best not to eat the water from the solar water heater, so as not to be harmful to your health.
