Solar water heater (ZJ-GJ)
Non-pressurized Solar Water Heater
|
Thermosiphon system
Using a thermosiphon solar water heater systems is an excellent way to start saving on your domestic hot water heating bills. The tank must be above the collector, so the thermosiphon phenomenon can occur, circulation water from collector to tank.
Advantages:
1. Can be operated completely automatic if connect with intelligent controller.
2. Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electric booster as to provide hot water without sunshine.
3. Superior heat preservation ensured by one-off molding polyurethane foam with thickness 50-65mm.
4. Suitable for camping area, holiday residences.
5. stable and reliable performance, well wind resistance.
6. Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B stainless steel plate; the silica gel ring sealing has a long life against the erosion and it ie not harmful to health.
