Abstract
A novel method is described for water heating using stored solar heat. Solar heat is stored in an insulated tank by using scrap and inexpensive heat absorbing or heat storing materials. Stored solar heat can then be used to heat water in a storage tank by extracting the solar heat using an antifreeze liquid which in turn heat cold water in the water tank. Water temperature in the storage tank is controlled by a thermostat. When the water temperature drops below the set point on the thermostat, a circulating pump turns on and pump the cold water until it reaches the desired set temperature. Once it reaches the set point in the thermostat, the water circulation pump turns off.
Claims27
A method of storing solar heat, comprising of
- directing the solar rays from a mirror to a lens into an insulated heat storage tank and absorbing the concentrated rays from the lens at the focal point by heat storing materials;
- and
- directing the solar rays from a parabolic mirror or magnifying glass into an insulated heat storage tank and absorbing the concentrated rays at the focal point by heat storing materials.
The method as defined in claim in 1, wherein the lens can be convex or Fresnel lens.
