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

- Q:Solar water heater should be simple to work about twenty words
- Than the significant drop in cold water. Hot water is always on the upper part of the tank. The temperature rise of the hot water in the solar water heater is not related to the outside temperature. When the opening of the kitchen or bath in any one of the taps, the water heater will rely on the natural fall out, the greater the gap, the higher the water pressure.
- Q:Why is the heating surface of the solar water heater tilted
- Because, we must rely on the high temperature of the water is heated, the proportion of light, light and hot water by hydraulic principle, by the heat collecting plate is set above the water into the water, by the back to the heat storage bucket of hot plate, so the collector must have a certain inclination angle, the installation angle of the generalAdd about 10 degrees to the local latitude..
- Q:Solar water heater is not hot how to do
- Solar energy is not hot, then there are several reasons for you to look at the sunshine time is short; A water heater in front of a shelter. B water valve off lax; vacuum tube memory scale heat collecting efficiency is reduced to C; the water quality is not good. E local air pollution is serious. The influence of heat collection; vacuum tube surface dust.F water tank all run out. Water tank capacity is small, that is, there is no basic water temperature. Large water consumption; G affected by weather. Troubleshooting: A for shelter or solar shift; B replacing C cleaning vacuum tube water valve; D; the vacuum tube surface clean; E replacement of large capacity water heater with electric heating system; pay attention to water heater water F analysis of weather conditions.
- Q:How to identify the solar water heater is good or bad?
- Insulation layer must be careful. The vacuum tube is pulled out, can be used in accordance with the insulation layer of polyurethane foam as a whole, if the hand by a soft feeling, then the foam, its short service life and easy to leak. If the hair is hard for polyurethane, with excellent thermal insulation performance.Depends on whether the stainless steel bracket genuine". Some water heaters say they are ultra-thin stainless steel stent, in fact, the texture is very poor, even galvanized support is not as strong. So be careful when choosing. At the same time it should be noted that, under normal circumstances, each person's water consumption is about 30-40 liters, consumers can choose according to the number of people in their own home to the corresponding capacity of the water heater.
- Q:Solar water heater is charged with heating or not good
- Is the factory with the uncharged and charged too much power, it is better to buy a live, plus a 40 liter water heater, three, solar heat without heating electric water heater, heat heating electric water heater to wash. Most power-saving.You buy a brand of electric water heater on the safe, such as Haier, Sacon, there are anti electric wall. Very safe. If you can buy a Taobao in the county or the city of Connor, Sacon is a product line, good quality and low prices. Take a look at yourself.
- Q:Who invented the solar water heater
- Archimedes stood up and shouted, "the sun is reflected in the sails of the mirror!" He raised the mirror, a light reflection to the side of the central sail, reflected a weak spot. A woman who understood him, hurriedly raised the hands of the mirror, the light is reflected to the sails, some light and small spot.
- Q:The solar water heater without water becomes bad
- If you do not use it for a while, it is recommended that you use a blanket, carpet or quilt to cover the vacuum tube to avoid sun exposure.Other parts of the air drying will not cause problems.
- Q:Selection of domestic solar water heater
- Businesses will talk to you as if it were raining flowers, but I hope you don't be fooled.Heard that the winter water pipeline easily donglie. Solar energy is not suitable for use in the north. My friend's solar glass tube burst once, how the water is also dissatisfied with the high water scare that month, exceeding the prescribed water consumption
- Q:What are the requirements of domestic solar water heater
- (3) when installed on the roof, the weight of the water tank, the heat collecting plate and the water shall be taken into account, and the load on the floor shall be increased. The influence of wind should be considered when the building is high.
- Q:When solar water heater comes into China
- The whole glass tube is in twentieth Century, the first by the United States Owens (Owens) company developed, not the invention of the Chinese invention of the.
