Introduction of Non-Pressure Solar Water Heater:

Non-pressure Solar Heater is one of the most economical solar water heating device with pretty high efficiency at the same time. It consists of hot water storage tank, solar vacuum tubes with mouth plug in storage tank, and bracket supporting tank and tubes.When cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to storage tank and colder water goes downward to glass tubes. through this continuous circulation, the cold water in storage tank will be gradually heated till sunset.


 

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

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

Q:What is the meaning of solar water heater overflow protection?
Need solar water, but the water level in the water heater installed outside the not timely, often water heater overflow caused by waste water heater now are installed on an overflow pipe is connected with water heater water storage at the highest level, end to the user's home, when the water is full of water will overflow since the flow prompts the user to turn off the tap in time. There is also a floating ball valve in the water heater, the so-called automatic Sheung shui. This is a water overflow protection.
Q:Solar water heater and radiator can be connected?
3, in order to ensure the stability of the temperature of the hot water system, also need to add a hot water storage tank, the excess heat storage when the sun is good, and then release the heat storage in solar energy shortage, to adjust the temperature of the hot water storage stability;4, the system needs to increase the circulation pump, the hot water tank in the hot water cycle, in order to ensure the end heating effect;
Q:What are the advantages and disadvantages of solar water heater?
Disadvantages of solar water heater:1, the initial investment.2, solar water heater installation position requirements are very strict.3, solar water heater for several days without water are generally more hot water, more than 70 DEG C, especially in summer weather more than 2 days, the water will boil, to be properly cooling at night, keep the water temperature at 60 to 70 DEG C. region for a long time, and this area is water temperature excellent temperature of the bacteria, so several days or without water, poor water quality, bacteria, to be discharged, can not take a bath or used for boiling water drinking.
Q:Advantages and disadvantages of solar water heater
Post cold phenomenon.4, in addition to rainy days, the use of solar water heaters do not need other costs, such as gas costs, electricityIn rainy weather, it is necessary to use auxiliary electric heating device, then you have to pay the electricity bill, in factIn rainy days, solar water heaters are still working, but the temperature of hot water can not reach the user washBath needs, but the water in the tank is warm, higher than ordinary tap water temperature, therefore, even ifIt is rainy day, it is also more than ordinary electric water heater.
Q:How to buy solar water heater to check its quality?
According to the number of households to choose different volumes of water heaters; must consider whether the use of all-weather, etc. 2: to understand the technical performance of products, mainly the average daily efficiency and average heat loss coefficient. At present, many people have a misconception that the higher the water temperature in the tank, the better the performance of the heat. In fact, the water temperature can not explain the quality of the product. Water temperature and sunshine intensity, sunshine time, water capacity, lighting area, the initial temperature of the water are related, so the most scientific way to talk about thermal efficiency and heat loss coefficient.
Q:Why solar water heater automatically add water
Solar water heater, if the water pressure is enough, can not Sheung Shui, to confirm that there is no leakage of water, the basic water temperature and water level sensor is broken;Vacuum tube type solar water heater is composed of a heat collecting pipe, a water storage tank and bracket and other related parts, converting solar energy into heat energy mainly rely on vacuum tube, vacuum tube using the principle of cold water sinking floating, the water circulation and desired hot water
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:Solar water heater is the number of 18 liters?
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. Vacuum tube type solar water heater is composed of a heat collecting pipe, a water storage tank and bracket and other related parts, converting solar energy into heat energy mainly rely on vacuum tube, vacuum tube using the principle of cold water sinking floating, the water circulation and desired hot water.
Q:Three homes to install solar water heaters, how many roots, the length of the vacuum tube appropriate?
I'll give you a professional analysis. I'm a solar water heater.1 vacuum collector tube. Be sure to choose the three high purple tube. Don't be an ordinary three executive. Collector effect gap,2 water tank insulation layer, the uniformity is better. Looking more uniform,. Slightly thicker. Relatively good insulation performance
Q:Why solar water heaters, hot and cold water temperature is not adjusted:
A mechanical mixer is normal, this is very difficult to control the contrast.
