3. Characters and advantages of heat pipe and U pipe collector:
1.) Reliable and efficient twin-glass solar tube+ heat pipe+ aluminum fins
2. )System can operate under high pressure (up to 8 bar/116psi)
3.) Adopt heat-tube heating technology, has low starting temperature, rapid diathermancy and high heat efficiency.
4.) Collector is separate from water tank and achieves integration with architecture and form an integrated part of architecture
5. )There is no water in the vacuum tube, so the tube will not break in winter.
6. )System can combine with existing energy source such as electric heater and boiler.
7.) It can be still operate in the event of occasional tube breakages.
8.) Manifold connection: 22mm Heat pipe：copper TU1，φ8×0.8。
9.)System can operate in cold temperature because it use anti-freeze liquid.
