Solar Water Heating Systems

Warm Stream offers Solar Water Heating System. This is designed to supply water at 80°C. The system consists of a corrosion-proof storage tank made from mild steel, SS 304 or SS 316 sheets. Collector casing: aluminium extruded sections of 16 swg thickness, weather tight construction, duly anodised and corrosion resistant. Glazing: single pan 4 mm thick, low iron toughened glass, rupture resistant and over 85% transmittance and low reflectance to eliminate glare. The absorber plate is made of grooved copper sheet and copper tube structure soldered to each other providing maximum contact area for excellent heat transfer between sheet and tubes. The plate is coated with black nickel chrome coating to produce a superior selective surface having 95% absorption and very low emission of 20% or black chrome coated. The back pan is made of aluminium sheet 20 swg thick duly anodised. The tubing grid is 12 mm; copper water way silver-brazed to 25 mm; copper manifold with an optimal ratio between diameters; piping connection can be made at four locations with the help of bolts and nuts with rubber seals between the joints.
