Using a thermosiphon solar water heater systems is an excellent way to start saving on your domestic hot water heating bills. The system is with a assistant tank, this assistant tank can feed the water Automatically

1. Can be operated completely automatic if connect with intelligent controller.

2. can be supplied cold water to water tank automatically

3. 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 tot water without sunshine.

4. Superior heat preservation ensured by one-off molding polyurethane foam with thickness 50 65mm.

5. Suitable for camping area, holiday residences.

6. stable and reliable performance, well wind resistance.

7. 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.
