This invention pertains to a submersible heater for a body of water and, particularly, to a highly portable comparatively easy and inexpensive submersible heater for alpha heater price swimming pools. It is one other object and feature 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 inside and outer radially spaced axially nested and alpha heater price extending cylindrical flue members each having an upper end supported on the aforementioned buoyant member so as to rely below the floor of the water with the buoyant member disposed therein, the lower ends of the internal and outer flue members being respectively open and closed to type a tortuous reverse move path for hot gases flowable down the inside flue member and up the outer flue member between the latter and the inside flue member, and burner means together with blower means mounted on the buoyant member above the surface of the water for burning an acceptable gas and blowing hot 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 similar.



Water alpha heater price 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 entirely submerged under the floor of the water with the buoyant member disposed therein, whereby water being heated may circulate through the aforementioned heating chamber between the opposite open ends of the jacket. I Figure 3 is a cross sectional view of the flue meeting of a water heater, however illustrates one more embodiment of the invention. 16 fabricated of a suitable metallic 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 a suitable steel and having an upper open end 24 and a closed decrease finish 26 axially reverse thereto.



20 of the latter spaced axially reverse 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 atmosphere via the annular exhaust opening 46 formed between the upper open ends 18 and 24 of the inner and alpha heater price outer flue members, respectively. Consequently, water surrounding the outer floor of the outer flue member is heated. 50 and 52, alpha heater price heater reviews respectively, of the water jacket are open and appropriate means akin to. Fifty four are welded between the outer flue member and the upper end of the water jacket to help the latter in axially spaced relation to the buoyant member or donut 12 in order that the complete water jacket is submerged. Water jacket forty eight defines with the outer flue member 22 an annular Water heating chamber fifty six through which water might circulate as it's heated.



Forty eight and fins fifty four could also be eradicated if desired and as shown, while the heater additional includes an annular plate 58 secured between the higher ends 18 and 24 of the inside and outer flue members to substantially close the annular atmospheric exhaust opening 46, though the plate fifty eight features a plurality of circumferentially spaced exhaust openings 60 for exhaust functions. 62 are provided, each having one finish suitably supported on the plate fifty eight in communication with a respective one of the exhaust openings 60 whereas the opposite or discharge end sixty four of each stack extends past the edge of the buoyant member or donut 12 and below the floor of the water for discharge of the combustion gases and merchandise beneath water level. 32 should not result in toxic, irritant-causing or in any other case objectionable merchandise of combustion for discharge into the swimming pool water and, therefore, one cause for the preference for using natural or propane gas because the gasoline. 22 with a plurality of axially extending circumferentially spaced fin members sixty six which improve the area of contact of the outer flue member with the water, thereby enhancing heat transfer to the latter.



66 may be utilized within the embodiment illustrated in Figure 1 which includes the water jacket forty eight and as indicated in dotted lines in Figure 3, or in the embodiment of Figure 2 for the purpose aforementioned. PORTABLE SUBMERSIBLE SWIMMING POOL HEATER Filed June 29, 1962 INVENTOR. AT/URIVE 6' United States Patent 3,194,229 PORTABLE SUBMERSIBLE SWIMMING POOL HEATER Donald R. Borgeson, 18301 Riverside Drive, Birmingham, Mich. Fiied June 29, 1962, Ser. No. 206,363 1 Claim. Cl. 126360) This invention relates to a submersible heater for a body of water and, specifically, to a highly portable relatively easy and cheap submersible heater for swimming swimming pools. It has heretofore been recognized as being fascinating to equip out of doors swimming pools, notably in additional northern climes, alpha heater discount with heating programs for heating the pool water within the curiosity of extending the swimming season to the maximum extent potential and to otherwise contribute typically to swimming comfort throughout the season reminiscent of on cool evenings and even during the day when unseasonably cool ambient temperatures'could happen.
