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

Q:Types of solar water heaters
Classification from structureThe utility model is characterized in that the vacuum glass tube is directly inserted into the water tank, and the water temperature of the water tank is increased by using the heating water circulation. Is also the most popular. Only the top layer can be used to change the type of water heater, unless the top user and the relationship between your downstairs special iron, and the roof area is limited. Split type water heater: split type: the solution is not the top users can also use solar water heaters. Split cycle 2, a water on the natural circulation, the heat exchange efficiency is low, can not meet the requirements of water; a pump circulation heat exchange, to solve the problem of low efficiency of natural circulation, pump circulation, can significantly improve the water heat exchange
Q:Why solar water heaters, hot and cold water temperature is not adjusted:
We can choose CNC thermostatic instrument, digital temperature, input of shower water temperature, start 5 seconds can be directly shower, do not need to repeatedly adjust memory function is preferred.
Q:How to correctly use solar water heater
D, the night after the bath, if there are nearly half of 70 hot water heater water tank, in order to prevent heat loss is too large (the less water, heat dissipation, faster) according to the weather forecast on the decision of water, sunny day, rainy day, full of water, the water is 2/3.E, the role of auxiliary water tank: auxiliary water tank is mainly used in the timing of water supply and water pressure instability region, the amount of water stored in the solar water heater between 1/2-3 times, installed on the roof, with the use of solar water heaters. The main function is to adjust the temperature of the bath when the water temperature, in addition to the water can be used to do with the water tank, but also can not be deposited in the water without water.
Q:Can you install solar water heaters on the slope roof
Can be mounted on the roof. But we must do a good job of fixing measures, can be used to wipe out a level of cement
Q:Solar water heater inside the scale how to clean it?
Cleaning method of solar water heater scale, the water out of the tank, the hands hold the vacuum tube rotate back and forth, make its loose, then turn on the water tank to the bottom to push out from the base, and then pulled down, so that you can remove the vacuum tube, the vacuum tube in the water drained, and then use clean water repeatedly rinse clean, which in turn will be vacuum tube after cleaning the tank to add tap water, so that the scale in the water tank outflow, and then one by one the vacuum tube can be installed, the installation should check the sealing ring mounting hole of the water tank is intact, if damaged, should be replaced with a new sealing ring.
Q:What is the capacity of a solar water heater in general?
Water heater insulation tank is generally 150 liters, 200 liters, 250 liters, up to 300 liters, and sometimes can be customized according to the user's hot water demand, the greater the number of heating pipe water heater tank, different manufacturers will be different.
Q:Air energy water heater and solar water heater which is good
The air relative to the solar water heater, the biggest advantage is to make up for the solar water heater can not produce efficiency all day long shortcomings, one night can only rely on the solar water heater water tank insulation effect to the temperature of the hot water has been saved to the night. After all, most people work during the day and go to bed at night.
Q:Solar water heater in a total valve when a pipe on the water.
If the three links above, indicating that the ball valve is a hot water switch. Then there should be a cold water pipe or a ball valve interface. It must have been less likely
Q:Two solar water heater is the connection method?
Because of the common solar water heater is the open water tank, when the water heater two side by side when pressure is the same, if you use the series, the first solar water heater into the hot water is water with tap water, but in second when there is no water pressure, so that the second sets of solar water heaters because there is no pressure to enter the water will be greatly reduced, in order to avoid this problem, suggest the use of parallel import of water, and the water outlet with a self suction booster pump to ensure the water pressure.
Q:Solar water heater can not put hot water
There are several reasons:1 solar water heater with water leakage phenomenon (check the upper and lower water pipes2 (check the indoor water mixer. Tap and other water points have no Water Leakage or no good)
