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 
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 in and out of the water pipes are connected to the home with the above?
Solar water heater is the first to enter the cold water storage tank, and then through the heat collector to heat the water tank. The heat storage water tank is connected with the indoor cold and hot water pipeline to form a closed loop. Reasonable design and proper connection of solar energy pipeline is very important for solar energy system to reach the best working condition. Solar energy pipe insulation must be done, the northern cold areas need to be laid in the pipeline with a tropical outer wall, in order to ensure that users can also use solar hot water in cold winter.
Q:How to set the solar water heater?
Controller problem.Emergency use, can be closed, or unplug the solar power.There are preset temperature is 65-75 degrees is appropriate.
Q:Three homes to install solar water heaters, how many roots, the length of the vacuum tube appropriate?
3 control instrument. These two sensors are most likely to be bad. (special attention must be given to lightning protection) general warranty is one year. What you say will give you an extension. Merchants can do the longest three years (this is a separate policy to manufacturers). General businesses do not want to look for trouble, only to the user that a year to see your eloquence
Q:What is the basic structure of solar water heater
The basic structure of solar water heater consists of the following parts:1, the collector, the collector is the core component of solar energy is solar energy into thermal components, collector and vacuum tube type flat plate, vacuum tube collector with high efficiency, good resistance to decay, winter can produce hot water; weak anti thermal shock is poor, will Water Leakage embassy bombing flat type; anti thermal shock is strong, but the thermal efficiency is low, the winter is not good; the solar collector is the heart of Everfount provide hot water;
Q:How solar water heater winter.
First, if the winter is no longer using solar water heaters, solar energy can be used up or emptied of water, the pipe is empty, it will not freeze.
Q:Do solar water heaters need electricity?
Photo thermo electric conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.Optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.
Q:How wide is the solar water heater?
The width of the solar energy depends on the number of vacuum tubes, and now the market for the sale of the brand of solar energy has sixteen tubes until the tube has thirty-six. The width of the smallest one meter a little more than the widest reach nearly three meters.
Q:How to use solar water heater heating by electricity
2 hot water bathWhen the water temperature in the water tank to bath temperature, open the hot water valve, regulating valve, spray head to warm water outflow for bathing, if the spray head out of the water is too hot or too cold, adjusted by the temperature regulating valve and cold water valve, water spray to head out of the appropriate date
Q:What is the role of the solar water heater's reflector
The sun light in order to better use of resources, using the reflection plate will be missing from the two middle tube reflect sunlight to heat the nightside, improve the heat absorption tube.
Q:Winter solar water heater easy to use
Many people want to install solar water heaters, because users can save a lot of money, and now the country to promote energy conservation and environmental protection projects. Such a thing for the country to their advantage no one wants to miss. However, the problem is that solar energy in the cold winter can not be used properly? Will not be frozen pipe it? Lead to solar energy can not be used normally? On this point there are a lot of customers to consult me, here I can tell you that as long as there will be hot water. As for the pipe will not freeze this we can be assured, because I also have agency in the Heilongjiang area, has been done for almost two years, sales have been very good, if you are living in an environment not cold there, please rest assured that!!!
