PRODUCT DETAILS

Heating Water Solar system uses stainless steel tanks and high pressurized technology to deliver reliable hot water all year round. Ideal for homes, hotels, hospitals, and industrial usage where stablepressure and high temperature are required.

Pressurized Solar Water Heater Working Principle:

●The heat pipe pressurized solar heater tank has no exhaust hole,therefore,it must bear the pressure come from tap water and hot water,when use,the hot water comes out because of water pressure.
●Vacuum tube absorbs solar energy,and conductive copper pipe transfers the heat into the pressurized solar water heater tank,In this case,the water inside the tank becomes hot.
●No water in the heat pipe makes the whole system can bear pressure.

High Pressure Solar Water Heater Key Advantages:

1.Start up quickly, heat pipe transfer the heat energy into the storage tank swiftly.
2.Withstand pressure of max 10bar, can be connected with city water directly, work automatically.
3. The storage tank and the heat pipe mechanical sealed, the solar water heater can still work even with several tubes breakage.
4. With reasonable design and choose excellent material, the inner tank is without any breakage after one hundred thousand time’s high pressure testing.
5. High density polyurethane foam, well insulation.
6. Can be installed in series and parallel to be a solar hot water system.
7. Can be connected with gas water heater and small boiler, also can preheat the water in advance.8. Can be installed in anywhere ( for example, you can install the solar water heater on the ground of the garden, and use the hot water on the third floor).

S.W.H with Copper Heat Pipe Advantages:

1. Transfer the heat energy quickly, we use special medium in the heat pipe and it can transfer the heat energy more than 1000 times faster than copper.
2. Highly efficient absorber, it increase 20% or more than ordinary solar water heater.
3. No water and no water scale inside the evacuated tubes, the tubes will not be cracked even if during – 40 Degree..
4. Withstand pressure of 0.7 Mpa, can be connected with the city water directly.
5. Can still work even with several tubes breakage. The water will not flow out from the storage tank.6. Can be used in sunny days even if in the extreme cold climate.

Solar Water Heater Mounting Surfaces and Direction:

Solar system can be installed on a flat roof or a tiled roof with maintaining the proper angles and directions.
Naturally you want the collector to receive the maximum amount of sunlight each day and throughout the year.
As a general rule if you are in the Northern Hemisphere then the collector should face south and if you are in the Southern Hemisphere then the collector should face north. See diagram below.

You do not have to be too careful about mounting the collector at the exact angle suggested. If your roof angle is within 10o+/- of your desired angle you can just mount the solar collector flush against the roof surface. The added trouble of adjusting the collector to a precise angle is not warranted as it will not result in a great improvement in efficiency.
