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

 

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

Q:Solar water heater inside the scale how to clean it?
1, water temperature for a long time to maintain above 70 degrees;2, the water is relatively static state.The composition or composition of the scale is complex, usually not a single compound, but a chemical composition, and contains other chemical components. According to the chemical composition of the scale, generally can be divided into several kinds of carbonate, silicate sulfate scale scale, scale, scale, scale, mixed oil and iron oxide scale and dirt etc..The scale is a poor thermal conductivity material, will hinder the transfer of heat, the water heater is not uniformly heated, causing local overheating, or partial pressure, eventually damage the water heater, even in danger.
Q:Solar water heater does not add water, the sun will not be bad in summer
Vacuum tube solar water heater with high efficiency in the summer, sunny weather conditions, less than two days water temperature can reach the boiling point, if a long time without water, such as travel, tourism, to make the water a long time at high temperature and high pressure conditions, will accelerate the aging of the sealing ring, accelerated aging, polyurethane shrink, sometimes not exhaust smooth, too much pressure will make the tank expansion bad, will shorten the life of furring, water tank. Therefore, if you are no longer at home, others often should arrange hot water or cold water in the vacuum tube collector is placed on the cover from the sun, stay home, and then removed. If the winter is not a long time. You need to cancel the electric heating setting, to avoid wasting electricity.
Q:Solar water heater to maintain it?
2, solar water heater in the use of the process should pay attention to what problems? Pay attention to water time. According to the weather conditions, determine the amount of water, to ensure that the appropriate bath temperature. Regularly check the water heater pipe, vent and other components are working properly. The air conditioning is serious or the sand is big, and the dry area is periodically flushed the vacuum tube.
Q:The solar water heater how to remove rust
The solar water heater, in addition to scale as follows:1, use both hands to hold a vacuum tube and rotating with the water tank, the sealing ring from loosening, and then to push a tank, when the bottom and the base can be separated, then the vacuum tube pulled out of the water drained;
Q:Solar water heater and radiator can be connected?
5, in order to automatically switch the solar energy and auxiliary heat source, need to increase the temperature detection automatic control system, give priority to the use of solar energy, solar energy is not enough to automatically start standby heat source.According to the design of the system, you can maximize the use of solar energy, in ensuring the premise of energy saving, the stability of the end heating temperature has been guaranteed.
Q:What are the advantages and disadvantages of solar water heater?
4, in addition to rainy days, solar water heaters do not need other costs,5, solar water heater safety is very high. Because there is no danger of electric shock or poisoning due to the absence of electricity or gas.
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:How long is the solar water heater used?
Two, insulation layer. The solar water heater production during the day of hot water stored in the storage tank, if the insulation heat preservation performance is good, overnight, rainy days can not be used or not used. That cause the insulation layer of the water heater insulation mainly due to the poor performance of the solar water heater, the insulation layer determines the how many hot water temperature and hot water level. The layer of imported raw materials, such as polyurethane insulation good, low thermal conductivity, high temperature resistance; automatic temperature high pressure foaming process and quantitative heat insulation, the high-temperature aging treatment, thermal insulation performance is high and stable and lasting. While some inferior materials with high thermal conductivity, no foaming uniform, night temperature can drop to ten degrees, encountered rainy days. There's no hot black enterprise, in order to reduce the cost, even the benzene board made, a few months after the insulation effect of straight down, after one or two years of basic. Three. Temperature, liner. At present, most of the solar water heater manufacturers said water tank is stainless steel. Stainless steel is the same, but chromium and nickel in stainless steel is not the same. Good solar water heater uses stainless steel high chromium nickel, ensure the bladder durable, strong corrosion resistance; inferior liner the use of low grade stainless steel, basic does not contain nickel, corrosion resistance performance is poor, life is short.
Q:Solar water heater vacuum tube length?
Now most of the use of 1 m length of 8. Solar energy is used to heat water by using the heat of ultraviolet rays
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.
