This invention pertains to a submersible heater for a body of water and, in particular, to a highly portable relatively simple and cheap submersible heater for swimming pools. It's one other object and have of this invention to supply a submersible waterheater for swimming pools comprising a buoyant member floatable on the surface of the Water in a pool, a flue meeting including inner and outer radially spaced axially nested and extending cylindrical flue members each having an higher end supported on the aforementioned buoyant member so as to depend beneath the surface of the water with the buoyant member disposed therein, the lower ends of the interior Heat Space Heater Official Site and outer flue members being respectively open and closed to kind a tortuous reverse stream path for hot gases flowable down the inner flue member and up the outer flue member between the latter and the inside flue member, Heat Space Heater Official Site and burner means including blower means mounted on the buoyant member above the surface of the water for burning a suitable gas and blowing sizzling gases along the aforementioned movement path, thereby causing heat to be transferred from the surface of the outer flue member to water surrounding the latter to Heat Space Heater Official Site similar.
Water heater of the type aforementioned additional comprising a cylindrical water jacket radially spaced from and surrounding the aforementioned outer flue member to define therewith a water heating chamber, the other ends of the water jacket each being open and the jacket being solely submerged below the surface of the water with the buoyant member disposed therein, whereby water being heated could circulate by the aforementioned heating chamber between the alternative open ends of the jacket. I Figure 3 is a cross sectional view of the flue meeting of a water heater, however illustrates yet one more embodiment of the invention. Sixteen fabricated of a suitable metal and having axially reverse open upper and decrease ends 18 and 20, and a second or outer axially extending cylindrical flue member or tube 22 likewise fabricated of an appropriate metallic and having an upper open end 24 and a closed decrease finish 26 axially reverse thereto.
20 of the latter spaced axially opposite from the closed ends 26 of the outer flue member. 12 disposed therein as clearly illustrated in the drawing. 22 is continuously heated and the combustion gases are exhausted into the ambiance by way of the annular exhaust opening forty six formed between the upper open ends 18 and 24 of the interior and outer flue members, respectively. Consequently, water surrounding the outer floor of the outer flue member is heated. 50 and 52, respectively, of the water jacket are open and appropriate means akin to. Fifty four are welded between the outer flue member and the upper finish of the water jacket to support the latter in axially spaced relation to the buoyant member or donut 12 in order that the complete water jacket is submerged.
