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:According to the installation of a solar water heater to the large area
Rainy weather heating and hot water utilization rate is fast, but also greatly reduced after-sales service, both time and energy saving. This type of solar energy than ordinary single warehouse in the absence of the sun heating time is only 20-30 minutes, and a single warehouse needs 2-3 hours!
Q:Solar water heaters are units used?
Because you said that the guests will sometimes have more than and 200 people, you can take a little bit, it is estimated that your unit design about 15 tons or so, if there is no special requirements, the cost should be less than 200 thousand.
Q:Excellent 800 solar water heater how to adjust the temperature to 30 degrees Celsius and intelligent mode
Solar water heater brands with different instruments are different, so the operation is also different
Q:Solar water heater is really easy to bad
Vacuum tube.Vacuum tube is the core component of solar water heater, but also the heart of the solar water heater. The performance of the vacuum tube is affected by the coating technology, such as cleaning, coating, vacuum pumping, sealing and so on. But some super low vacuum tube using the solar water heater has the following defects: low vacuum, only quality products 1/100 tube residual impurities and water vapor, a high temperatures encountered into gas, vacuum reduction; low vacuum film stability of two or three years, intimal layer aging, fall off, resulting in the thermal performance decays rapidly, unable to absorb enough heat
Q:How to deal with the solar water heater hot water pipe
The two kinds of temperature control is a control of water heater temperature display and control, one is to avoid the problem of temperature control at room temperature.
Q:My solar water heater is 365 days a year to open the power supply, would like to ask the next solar water heater has been able to open it?
No, my home in addition to Sheung Shui, never external power supply, what your home solar water heater
Q:I only have the above solar water heater, there is no accessories, which parts need to install it
Not so complicated, two solar energy fittings, or two wire directly, either a faucet elbow a wire three. Two water pipes, one on a backwater. Inside a mixing valve nozzle, mixing valve head with solar energy, the head is connected with the tap water, even can be used.
Q:Solar water heaters have an impact on people's health?
Again, the water storage container in the water heater is not in accordance with the drinking water supply equipment (such as drinking machine) of the standard design, its internal health conditions are relatively poor, attached some harmful substances, so that the water quality is not up to the standard of drinking water.
Q:When is the best solar water
Generally set in the water between 8 to 9 in the morning, so that the sun came out on the heating, and the previous night did not run out of hot water due to good insulation, Sheung Shui is still available before, if the water will be a waste of water in the evening.
Q:Winter solar water heater easy to use
And this is a concern for many people, if not the use of solar energy in winter that means the utilization rate of solar energy is only half, this will greatly increase the cost of installation of solar water heaters, forcing consumers to choose other water heater system. In fact, the solar water heater technology now, the use of solar energy in winter is not a problem, as long as the snowstorm raging will not stop working, solar energy, free life hot water for our time.
