300 Liters Sunrain Pressurized Heat Pipe Solar Water Heater

Technical Details

Free Maintenance

No glycol, simple structure. No annual and periodical check-ups or maintenance is necessary. Blind sleeve design, no pollution, no-leaking heat pipe, easy installation. No water in vacuum tubes, one broken tube will not affect the function of the whole system.

High Performance

With cutting-edge vacuum-tube collecting technology, over 92% of sunshine energy is converted to thermal energy for heating and no circulation loss. Thicker insulation layer, functioning well in winter, even in the minus-30-degree environment.

High Reliability

The system is simply working with the city’s net water, without pumps. The inner tank is made of stainless steel SUS316-1.2mm. Working with high pressure, directly connected to running water, automatically functioning. The T/P valve and exhaust valve, protects the tank from shrinking.

Year-round Operation

With freezing-proof technology, the system is designed and installed to operate for all seasons. An electric heater is optional use, to ensure plenty of hot water on rainy days.

Customer-friendly

Vacuum tubes are directly connected to the tank, with low heat loss. The blind sleeve design and SUS316 inner tank are suitable for poor-quality water supply areas. An aluminum alloy frame is optional. Install angle(degree): 30/45. The pipe location on the tank is optional. It’s cheaper than the split pressurized system.
