Product Description:

Solar water heaters features
1. The upright tank can make the water temperature to a high level. It can hot the water instantly
2. The tank inside the building, the hot water loses less energy than the normal one 
3. The solar collector and the tank of solar water heater is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around 
4. Back up with electric heater so that in the day without sunshine hot water can also be used
5. Can be combined with gas or electric heater 
6. Max. Pressure: 12bar; Operating Pressure: 6 bar
7. It can be used for other function, such as warming

 

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

1. Operating screen 
2. Manometer 
3. Pump speed adjust switches 
4. Temperature difference circulation pump 
5. Flow rate indicator 
6. Return circuit connector 
7. Safety valve

Q:Solar water heater in the end do not use electricity
The solar water heater absorbs the heat from the sun to heat the water through the solar heat collecting plate, and when the weather is rainy for a long time, the electric heating is needed. Electric auxiliary heating with electric water heater heating is almost the same, direct heating water temperature.
Q:How to deal with the solar water heater hot water pipe
There is to see whether or not the hot water pipe water supply, water supply will directly lead to the water heater can not be used, because the principle of electric water heater is cold water running hot water, see if the water heater is blocked. Some because the temperature trip will directly lead to hot water. So that professionals will soon be ready to boot.
Q:Selection of domestic solar water heater
Specific purchase as far as possible the selection of large brands, according to the family population, the use of the choice of capacity, such as three people at home, but also with hot water washing clothes and so on to choose more than 185 liters
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:Solar water heater can not adjust warm water
This is a hot and cold water pressure difference, the solar water heater usually we buy most of the drop type solar water heater, the water heater for hot water down the gap (the gap is larger water pressure, water pressure drop is small, so the smaller) hot water pressure is very small. Water temperature is not high, it is relatively easy to adjust, when the water temperature is not good adjustment. This is because the general situation of cold water pressure in two to three pressure, while the drop type solar water heater is generally the top layer of pressure in the pressure of about zero point three, the pressure difference between cold and hot water is very large. The water temperature is not high, because the small cold, so cold water pressure will be reduced, this time it is easier to adjust; the water temperature is high, because a little hot water will be a lot of cold water to reconcile the suitable water temperature, then hot water is very small, less pressure, cold water to open a large, between them the pressure difference is greater
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?
So, the water in your tank is about 45-80 degreesThere is no possibility of explosion, as you said that the accident, nor because of long-term solar energy!
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:Is the solar water heater automatically supplied by temperature?
Set for the timing of water is good, water temperature control, timing Sheung Shui is generally one of the 2 election, the control board can only perform a function, always dissatisfied with your sensor is not good, is not conducive to the protection of sensors
Q:Solar water heater water pipe with plastic tube or PPR tube good
Aluminum plastic pipe is a kind of middle longitudinal welded aluminum pipe, the inner and outer layer of polyethylene plastic and between layers of hot melt adhesiveA new type of composite pipe. Polyethylene is a non-toxic, odorless plastic, with good impact resistance, corrosion resistance, weather resistance. The compressive strength of the middle layer longitudinal welding Aluminum Alloy tube with metal, the impact resistance of the pipe is easy to bend rebound, aluminum-plastic composite pipe with metal pipe and plastic pipe two strong pressure characteristics of anti acid corrosion resistance, is a model of a new generation of pipe. Plastic pipe (plastic composite pipe) is a kind of pipe is more popular on the market, the current market there are relatively well-known HSBC, Kim and Meifeng, due to its lightweight, durable and convenient for construction, and the aluminum pipe (plastic composite pipe) can bend more suitable for use in the home.
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..
