Product Description:

Solar water heaters features
1. The upright tank can make the water temperature to a high level. It can hot the water instantly
2. The tank inside the building, the hot water loses less energy than the normal one 
3. The solar collector and the tank of solar water heater is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around 
4. Back up with electric heater so that in the day without sunshine hot water can also be used
5. Can be combined with gas or electric heater 
6. Max. Pressure: 12bar; Operating Pressure: 6 bar
7. It can be used for other function, such as warming


Solar water heaters working principle
1. The solar collector absorbs solar energy and transmits it to the solar water heater tank through circulation 
2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank. 
5. When the temperature difference between solar collector and heat pipe solar water heaters tank doesn't reach the set value, the circulation pump will be shut automatically 
6. In case the temperature of the water tank does not reach Tmax, Electric Heating Element will start to work automatically


Solar water heaters working station component:
1. Operating screen 
2. Manometer 
3. Pump speed adjust switches 
4. Temperature difference circulation pump 
5. Flow rate indicator 
6. Return circuit connector 
7. Safety valve 
8. Expansion vessel connector9. Return circuit connector 
10. Wall mounting 
11. Expansion vessel:8L 
12. Pressure resistance: 10 bar pressure for expansion vessel

Q:Solar water heater intelligent measuring and controlling instrument. How to cancel the timing
First, the main technical indicators1, the use of power supply: 220VAC power consumption: <5W2, temperature measurement accuracy: + 23, temperature range: 0-99%4, sub Filelevel: Five5, solenoid valve parameters: DC DCl 2V, you can choose a pressure valve or no pressure valveTwo, the main function1, the boot self-test: boot when the "beep" tone, indicating that the machine is in normal condition2, water level preset: preset water level 50, 80, 100%3, water level display: display all the water inside the solar water heater4, water temperature display: solar water heater can display the actual water temperature5, water temperature preset: preset heating temperature 30%-80%, if not heating function, can be preset to 00 degrees C.
Q:Solar water heater for Hotel
The utility model has the advantages of stable hot water, convenient use, no need to be used for it, no need to be bothered, and the traditional positive displacement electric water heater is the best choice. Has been quite mature, can not leak for decades, like high-grade real estate almost all supporting the volume of water heaters. Nothing more than stability, do not want to bother, do not want someone to repair the door.
Q:Solar water heater installed under the probe leakage
In this case, it is possible that the casing of the sensor string,You go up to half of the water level,
Q:What is a solar water heater? Solar energy water heater is not only to buy it
If the heat collecting effect of the solar water heater is not good, can also be a vacuum tube that can go upstairs and see if the vacuum tube, color white, touch with the temperature, the vacuum tube that has been damaged, lost in heat insulation function, should be replaced.
Q:Solar water heater in use should pay attention to what?
Sheung Shui is best at night or in the morning. In sunny weather conditions, the first water or water tank is more than 15min, otherwise the day can not Sheung Shui, water and air drying and high temperature of 270 degrees, the vacuum glass tube will suddenly freeze and burst or vacuum tubes of scale.
Q:How to deal with the solar water heater hot water pipe
There is to see whether or not the hot water pipe water supply, water supply will directly lead to the water heater can not be used, because the principle of electric water heater is cold water running hot water, see if the water heater is blocked. Some because the temperature trip will directly lead to hot water. So that professionals will soon be ready to boot.
Q:Solar water heater in a total valve when a pipe on the water.
If the three links above, indicating that the ball valve is a hot water switch. Then there should be a cold water pipe or a ball valve interface. It must have been less likely
Q:Solar water heater is how to work?
Is not the normal operation of solar power, but in the rainy days continuous, start power consumption of electric auxiliary heating, electric auxiliary heater is 1500 watts, is the general temperature control, electric heating temperature is about 65 degrees, the highest temperature of the solar sun rises by 100 degrees. The market generally buy a vacuum tube type solar vacuum tube solar heating principle is in the water, on the thermal siphon vacuum tube hot water to the water tank, and the cold water in the water tank into the vacuum tube, these are microcirculation.
Q:How to use solar water heater controller
Take a look at this line is not, the general control instrument used are almostThe use of solar water heater microcomputer intelligent measurement and control instrument
Q:Solar water heater with too long how to clean?
Specific method is:1, when all the water in the water tank is completed, each vacuum tube with both hands to hold back and forth rotation, so that the vacuum tube and the water tank on the loose ring, and then pushed into the tank;2, when the bottom of the vacuum tube can be removed from the fixed base, then the vacuum tube out of the water tank out;
