Curved surface absorber type solar fluid heater

A curved surface absorber type solar fluid heater for heating fluid, comprising:

• a base insulation having a vapour barrier covered by reflective foil;
• a glazing, the glazing having at least two radially spaced transparent hemispherical curved surfaces, closed at bottom periphery, defining an exterior surface, an interior surface, and a first chamber therebetween, the glazing being supported with a support grill, the glazing being supported on the insulation base through a peripheral insulation ring;
• a collector disposed within the interior surface of the glazing, the collector having at least two radially spaced hemispherical curved surfaces, closed at bottom periphery, defining a second chamber therebetween, the collector positioned on the base insulation along the peripheral insulation ring, the collector configured to receive a fluid to be heated therein, the collector having an air vent configured on a highest position thereof, the collector having a drain plug configured on a lowest position thereof, and wherein a whole hemispherical surface of the second chamber is utilized for heating of fluid;
• a hot fluid tank, the hot fluid tank having a hemispherical configuration, the hot fluid tank positioned within an enclosure formed between the collector and the base insulation, the hot fluid tank having an outlet pipe and a hot fluid tank non-return valve connected to a top end thereof and in fluid communication with the second chamber, wherein the non-return valve is a pivot type dead weight inclined with said base insulation at an angle greater than 0° and less than 90°, said non-return valve configured to prevent backflow of fluid from the hot fluid tank towards the collector during an absence of solar radiation, the hot fluid tank having an opposed pair of recirculation connectors connected thereto;
• and
• a locking arrangement facilitating locking of the collector and the glazing on the base insulation, the locking arrangement including a plurality of strips, a plurality of screws, a bottom locking plate, a top locking plate, and a locking clip.
