Solar fluid heater

A non-hermetic flat plate solar fluid heater comprising:

• a. a first planar outer cover and a separated and parallel disposed first selectively coated absorber means for collecting and transmitting solar energy to a fluid to be heated,
• b. a first plastic convection suppressor means having a plurality of surfaces disposed intermediate to and in an abutting relationship between said first planar outer cover and said first selectively coated absorber means for forming a plurality of closed compartments for reducing heat losses,
• c. a plurality of passage means for carrying the fluid to be heated being disposed at one of its sides adjacent to aid first planar selectively coated absorber means,
• d. a second planar outer cover and a separated and parallel disposed second selectively coated absorber means disposed adjacent to the other side of said plurality of passage means for collecting and transmitting solar energy to the fluid to be heated, and
• e. a second plastic convection suppressor means having a plurality of surfaces disposed intermediate to and in an abutting relationship between said second planar outer cover and said second selectively coated absorber means for forming a plurality of compartments for reducing heat losses and for forming a dual sided unit.
