Claims4
Apparatus for heating water in a reservoir comprising
- a closed pipe system encircling at least part of the expanse of the reservoir interiorly thereof and said pipe system being disposed above but adjacent the water surface,
- an air supply conduit in communication with said pipe system, there being embodied therewith means for supplying heated air to said supply conduit for communication thereof to said pipe system,
- said pipe system having a plurality of outlets spaced therealong and said outlets facing downwardly angularly toward the surface of said water, and
- a corresponding plurality of flexible hoses connected at one end to each outlet, each said hose in the absence of air flow therethrough extending downwardly into the water with the other end thereof submerged below the surface of said water, said hoses distending when air flows therethrough, the weight of said hoses establishing an equilibrium condition countering the buoyant effect of such air flow to maintain the said other ends of said hoses adjacent to but below said water surface.
