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:How to defrost the solar water heater
A better way is to pay close attention to the weather, when the temperature is below zero, it will open the antifreeze device, the solar water heater to preheat protection without worrying about the problem of electricity consumption. Especially in the northern cold region, when the temperature is always at minus, it is necessary to open the heating antifreeze device. Other areas if the night temperature is relatively low, you can start in the evening antifreeze, closed during the day. In the bath, but also pay attention to unplug the plug, cut off the power supply, to prevent heat balance out of control accident.
Q:How to use solar water heater for temperature sag
Increase the use of hot water when the number of sunny temperature lower than -5 DEG C, several times a day to use a small amount of solar water heater in the water, but also can effectively prevent outdoor pipeline blockage or cracking. The lower the temperature, the number of hot water to the more frequently, in order to prevent the freezing of water pipes.
Q:Working principle of solar water heater
Is the domestic vacuum tube solar energy? There should be also from the water tank, if you use the water cold storage water tank of solar energy should be higher than 5 meters, the cold water in the water tank is no pressure, not their own water, if the conditions are not allowed, only low solar position, it must be installed a water pump to pump water! Hope to solve your problem!
Q:Long term use of solar water heaters should not be how to maintain?
Long term maintenance method of solar water heater:1 do a clean up and clean the water heater.
Q:Solar water heater does not add water, the sun will not be bad in summer
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, so there will be no problemOther parts of the air drying will not cause problems
Q:6 people with a number of tubes to install solar water heaters
Vacuum tube type solar water heater is composed of a heat collecting pipe, a water storage tank and bracket and other related parts, converting solar energy into heat energy mainly rely on vacuum tube, vacuum tube using the principle of cold water sinking floating, the water circulation and desired hot water.
Q:How solar water heater winter.
The residual water in the pipeline pumping back to water tank, so every time when the water is hot water, cold water is not discharged, saving water and avoid water pipes frozen in winter.
Q:Air water heater advantages and disadvantages?
Shortcomings:1 large size: air source water heater can generally be divided into integral and split two, because the city family bathroom is generally small, so no matter what kind of type, its huge body or let consumers. And requires the installation on the ground or roof, the home environment requirements are relatively high.2 frost: obvious regional characteristics, because of its environmental temperature dependence is too large, easily affected by the surrounding air environment, where the weather was cold, when the ambient temperature is low, the production of hot water quantity will decrease slightly. Therefore, the problem is also a big problem to solve frosting.3: easy to burn out compressor currently on the market of air circulation heating system is widely used in water heater, running at high temperature and high pressure conditions, easy to make the compressor aging, carbonation, if the lubrication system is not good, it is easy to cause the compressor to be burned.
Q:Solar water heater has been to overflow water
(2) backwater pipeline is too long or not smooth, resulting in water after the water can not be discharged from the back of the pipeline, the actual water tank is full, continue to water will be out of the other vent hole. Solution: the problem is a natural law, the use of return water pipe can not be ruled out, the installation of instruments to solve the problem.
Q:Solar water heater can be used in winter?
Solar water heater in winter in most parts of our country can be used. In the case of freezing in the northern winter, use the following:
