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:There is a solar water heater and then install a gas water heater, how to install?
Methods: in the valve below the solar energy plus a 3 pass, a head connected with a water inlet, a head connected solar water valve, a head connected with the gas heater and a valve, usually with solar off when the addition of the valve, gas heater outlet pipe to hot water pipes, also want to add a 3 this is very convenient.
Q:Solar water heater is the number of 18 liters?
The utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production.
Q:What is the structure and principle of solar water heater?
The solar water heater converts the solar energy into heat energy, and the water is heated from low temperature to high temperature, so as to satisfy the hot water use of people in life and production. The utility model relates to a solar water heater which is composed of a heat collector, a water storage tank and related accessories. The collector surface by the sunlight, high temperature, low temperature and heat nightside, produce water pipe temperature, using the principle of cold water sinking floating, the water circulation and desired hot water.
Q:Solar water heater is water riot or anhydrous riot
Solar energy will be the main components of the unexpected burst vacuum tube, the correct use of the case will not happen.
Q:What is the basic structure of solar water heater
3, support, is responsible for supporting the fixed water tank and heat collector components, like the human thigh, so that the water tank heat collector Station facade to the sun;4, pipeline, pipe is connected with water points and solar components, like the blood vessels will be sent to the hot water, cold water to the tank;5, intelligent control system, intelligent control system is like the human brain, control the safe operation of the entire solar energy.
Q:How wide is the solar water heater?
There is also a balcony wall mounted solar energy, with a hot plate to replace the vacuum tube, the width is generally less than one meter, the length of two meters to nearly four meters.
Q:When is the best solar water
When there is water in the bucket (to determine the water can be released), can be injected at any time.
Q:What is the role of the solar water heater's reflector
Solar vacuum heat collection tube, because of installation, sealing and other reasons. It can not be arranged closely
Q:OEM solar water heater 10I'm going to get some solar retail
It is not to say that the OEM is false, some manufacturers of the product quality is more clearance, otherwise those manufacturers will not braved the risks of reputation to stick, first of all, even the OEM, or their customer service phone, like 400*-***-*** phone, these are safe.
Q:Buy solar water heater enough to wash five people how much money
(single warehouse number and the number of the corresponding solar tube, Sancang solar energy requires a large specification)
