unpressurized solar water heater

unpressurized solar water heater Working principle: when the diffeference of collector temperature and tank temperature gets to the set value, the circulation system will start work. It will transmit the solar energy from solar collector to the tank. Saikangsolar water heater features: a. Module design, arbitrary combination, harmonize with the building perfectly b. Intelligent control and automatic operation c. Anti-freeze: Using the anti-freezing liquid as the medium and the controller has the anti-freezing function d. Multifunction: bathing, washing, domestic heating etc. e. Work at anytime and enjoyable. f. Material of Model: 1) The pipeline is made of red copper and conducted by heat transfer medium liquid 2) Temperature preservation is equipped with standard electric water heater setting, automatic temperature control exchanger, and increased anode magnesium bars sticking to prevent furring 3) The insulating layer uses polyurethane bulk bubble and has a good effect of temperature preservation 4) Water tank (interior):Stainless steelinner tank 5) Manifold : aluminum alloy outcasing& red copper flow passage 6) Glass tube: new trivalent element heat tube, borrosilicate glass 3.3 7) Solar working station 8) With heat pipe: anti-freezing > -35 degrees centigrade 9) Water capacity: 150L, 200L, 250L, 300L, 500L 10) Pressure: 6 Bars 11) Daily efficiency: >= 55%(>=42% in winter) 12) Heat preservation: 72h to 80h 13) Electric heater: 1.5Kw to 3Kw
