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 the 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 minus-30-degree environment.
High Reliability
System is simply working with the city net water, without pumps. Inner tank made by stainless steel SUS316-1.2mm. Working with high pressure, directly connected to running water, automatically functioning. With T/P valve and exhaust valve, it protects the tank from shrinking.
Year-round Operation
With the freezing-proof technology, the system is designed and installed to operate for all seasons. Electric heater is optional to use, to ensure plenty hot water in rainy days.
Customer-friendly
Vacuum tubes are directly connected to the tank, low heat loss. Blind sleeve design and SUS316 inner tank is suitable for poor quality water supply area. Aluminum alloy frame is optional. Install angle(degree): 30/45. Pipe location on the tank is optional. It’s cheaper than split pressurized system.
300 Liters Sunrain Pressurized Heat Pipe Solar Water Heater installation Considerations
Before installation, please note:
1. Check the density, hardness and strength of roof structure to ensure safety of solar water heater.
2. The maximum snow load is: 1.2 times the weight of tank
3. Maximal wind resistance for the frame is 1000Pa, according to ENV1993-1-1.
300 Liters Sunrain Pressurized Heat Pipe Solar Water Heater Solar System Location
The solar system must be installed in a non-shaded place. High buildings or trees may cause shade to solar water heater and reduce its performance. For optimum performance, solar water heater should be installed facing towards the equator. For South Hemisphere solar water heater should be installed facing north, while for North Hemisphere should be facing south. Diverting for this north/south orientation is possible, given installation site conditions, and is best considered by your dealer’s appointed professional installers.
