Non-pressurized solar hot water

Working Principle:

This system uses the thermosiphon principle, Solar vacuum tube is pluged into the bottom of water tank, The water is filled inside the solar vacuum tube, Solar vacuum tube transmit solar energy to heat energy, The temperature of water inside solar vacuum tube is rising, As the thermosiphon principle, the hot water rise up, and arrive in the water tank, the cold water inside the water tank go down the solar vacuum tube, so the system runs by this circulation way until the water become very hot. The highest temperature of water tank can be 95 degree Celsius, During this process, this system doesn't need any power, just under the sunshine. It is a green product.


1) Thickness of bracket: 1.5mm2) vacuum tube: 58 mm x 180mm three target3) Inner tank:0.3mm SUS304-2B food grade stainless steel4) Outer tank:0.4mm painted steel5) Capacity: 120/135/150/160/180//200/250/300/350L6) Insulating layer thickness: 45 - 50mm7) Inner tank thickness of: 0.31mm8) Tank diameter: 450mm-470mm9) Pressure: 0Pa10) Heat preservation: 72hrs11) Hail resistance: 25mm


1,The inner tank uses fully-automatic seamless pulsed argon arc butt welding,which can prolong the life and resist corrosion

2,The density of the polyurethane is 37-40kg/m3 to make the thermal insulation time reach to 72 hours;

3,The vacuum tube,frame and water tank are all produced by MEIDA, so quality is very Stable and delivery is on time;

4,P&AL film is attached around the inner tank to obstruct the thermal radiation and reduce the heat lose from water tank

5,Collector efficiency remains high even in cloudy conditions;

6,Can operate without any electricity;

7,Easy to install(plug in), maintenance free. High efficiency and long time proformance.

8. Work temperature≥-10°C


The non-pressurized system is based on the natural circulation-thermosiphon phenomenon. It's the most cost-effectiveness and environmentally friendly way to harness solar energy for hot water applications, which is unsurpassed by any other solar thermal products, for its most high efficiency, low cost, easy installation.
