non-pressurized solar water tank
solar water tank
1,Inner tank:SUS304-2B material,150L-200L1.2mm thickness,300L-400L1.5mm2,Insulation:50mm polyurethan foam3,Outer tank:0.5mm thickness galvanized steel material4,P/T relief valve ,electrical heater element with terminator5,Heat exchanger:20m long,12mm diameter,1mm thickness coppper pipe.
Features:• Two layers of vacuum tubes and one absorber fin to ensure high absorption and conductivity.• Heat conducted by the medium inside heat pipe transfers the heat faster and more efficiently. • Reliable high pressurized water inner tank of 1.5 mm thickness and 55 mm of insulation to lockup the temperature.• Freeze proof. Since there is no water in the vacuum tubes it will not freeze - ever. It will not affect the efficiency of the heat transfer• A couple of hours of daylight are enough to have a permanent hot water supply even on rainy and cloudy days. Since the glass vacuum tubes absorb ultraviolet rays.• Since the vacuum tubes have a circular shape always the sun is striking their rays perpendicular to the tubes at any time from Sunrise to Sunset• The sealed glass evacuated tube provides a stable supply of heat even during intermittent weather. There is minimal “peaking and toughing” of heat supply as the clouds intermittently block the sunlight. Heat supply can therefore continue even when there is no sunlight striking the collector, due to the store of heat within the evacuated tube.• If a tube breaks there is no water leak• If a tube breaks it can be easily replaced without the system having to be shut down.• No lime or water scale.• Turn on the tap, there is immediately hot water and the water is so clean because it uses the water directly from the tap, not from the tank• When you take a shower you feel the pressure of the water, like feeling a relaxing and powerful massage.• Thermal tank keeps the water hot up to 3 days if there is rain or cloudy days.• Electric backup heater of 1500W, useful if weather condition does not improve.• Digital Solar Water Temperature controller to keep your water hot at your temperature desired.• Free maintenance.• DIY Installation easy to follow step by step.• It can be installed on Ground, Flat or Pitched Roof• 15~20 years life span.
