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

Q:How to set the solar water heater?
Thank you for the use of color LCD products, TMC extreme solar water heater all-weather measurement and control instrument is the application of new technology to develop a single chip binding solar dedicated equipment. Features: color liquid crystal display, use the menu navigation buttons, rich function, convenient operation, early and late original all-weather timing model, anti electric tropical fire, automatic anti overflow, power continues to show the pipeline circulation function, look glamorous, full of extraordinary taste.
Q:Solar water heaters do not want to do too hot water
Solar water heater, do not want too hot water, you can use the following methods to solve:1, the installation of a thermostatic valve can automatically adjust the water temperature;
Q:Is the solar water heater working normally?
It looks like a smoke, in fact, it is water vapor, and we are about to boil water is the same reason.
Q:Installed solar water heater really worthwhile?
Economic angle:A solar energy can be used 10-15 years, priced at around 4000.One year, even if the winter, as long as the sun, lighting is good enough, the water temperature can reach 60 degrees.Then you think about how much money you can get 4000 dollars, how long can it be used?Safety:Solar water heater (without electric heating) is very high security, no basic security risks.Continued:If the weather is good, the water temperature is higher, and you can not use so much water, solar water heater insulation effect can let you in the next few days do not have to worry about hot water problems.Maintain:Solar water heater in addition to the sensor probe is prone to problems, other parts are rarely problems.Solar energy is also flawed:The weather is more likely, you may use hot water today, but there is no sun. (so the need for auxiliary heating equipment)After installation, want to move very troublesome.Installation risk because of the roof.
Q:Air water heater advantages and disadvantages?
It can also play a role in purifying indoor air. 2 efficient dehumidification, convenient and comfortable, 24 hours a day, the maximum amount of moisture in the 6-8 kg, rainy weather and more obvious effect, especially suitable for wet southern weather. Regardless of weather year-round snow, 24 hours of uninterrupted continuous automatic hot water supply, but also convenient than the conventional solar water heater. 3 safety, air water heater can not use gas, so it can be ruled out carbon monoxide poisoning. Will not be heated with electric heating rod, the possibility of excluding leakage. So more secure. 4 to achieve the system operation automation, automatic operation, no duty, with temperature control device and insulation layer, can automatically pay, heating, power, can provide hot water 24 hours. Users can enjoy hot water at any time under any weather conditions.
Q:How to clean solar water heater
5, clean solar water heaters in the water tank should be carried out regularly, generally according to the local water quality situation, do not need frequent cleaning.6, usually should pay attention to the use of solar water heaters, water temperature inside the water tank below 75 degrees, is not easy to produce scale, so the summer or spring and autumn, add water according to the weather conditions, if the sun is good, the water in the water tank should be used with, this temperature will decrease with tap water to avoid filling. The generation of the scale.
Q:The controller of the solar water heater does not show the power on screen
The utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production. According to the structure of the solar water heater is divided into vacuum tube solar water heater and flat type solar water heater, mainly vacuum tube solar water heater, occupy 95% of the domestic market share
Q:What is the quality standard of solar water heater
3 bracket. Support must be able to withstand all kinds of corrosion, or have 3-5 years after stent decay, collapse, the solar energy would be ruined, do not buy that support the paint on the brush, brush to paint on the easy detachment, scaffold exposed part is easy to rot, is not to buy stainless steel bracket. Stainless steel is not easy to rust, but the stainless steel material is soft, the bearing capacity is weak.4 liner, at present, most of the solar water heater manufacturers are said to be stainless steel water tank liner. Stainless steel, but chromium and nickel in stainless steel are very different. Good solar water heater uses stainless steel high chromium nickel, ensure the liner durable, corrosion resistance is strong; the use of low grade stainless steel liner is inferior, basic does not contain nickel, corrosion resistance performance is poor, short service life.
Q:What are the types of solar water heaters? What advantage
From the heat collecting partGlass vacuum heat collecting heat efficiency: is the highest part, the advantages of the heat collecting part does not need to increase in the thermal insulation layer, the vacuum glass tube now in high temperature, anti crack and thermal insulation performance, are the best, most manufacturers are using. The disadvantages of large volume, easy to scale pipe scale. Metal plate: excellent heat transfer performance of the metal sheet, covered with heat absorbing coating, the use of metal heat transfer, the heat absorbed in the tank. The utility model has the advantages of beautiful appearance and convenient installation, can be made into a flat plate, and is not easy to be damaged. Disadvantages: insulation to spend a high price, high cost, indirect is to increase the burden on consumers;
Q:How to choose solar water heater?
In the thermal performance index, the higher the average daily efficiency is, the better the average heat loss coefficient is.2 home solar water heater is the key component of all glass evacuated solar collector tube (referred to as vacuum tube), the quality of vacuum tube directly affects the performance of the entire household solar water heater. Purchase should be carefully observed in the vacuum tube glass coating on the tube, the coating layer is called solar selective absorbing coating, because the factory production process, color coating will be different, but generally are black, dark blue or dark gray, good quality coating color uniformity film, no scratches, no peeling or shedding the phenomenon, no glass or stone section of tumor, supports the glass pipe in the correct place, not loose.
