Legal standing (The legal standing is an assumption and is not a authorized conclusion. Current Assignee (The listed assignees may be inaccurate. Priority date (The precedence date is an assumption and isn't a authorized conclusion. This invention pertains to a submersible official Alpha Heater site for a body of water and, in particular, to a extremely portable relatively simple and cheap submersible heater for swimming pools. It's another 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 assembly including inside and outer radially spaced axially nested and extending cylindrical flue members each having an higher end supported on the aforementioned buoyant member in order to rely under the surface of the water with the buoyant member disposed therein, the lower ends of the inside and outer flue members being respectively open and closed to form a tortuous reverse flow path for hot gases flowable down the interior flue member and up the outer flue member between the latter and the inner flue member, and burner means including blower means mounted on the buoyant member above the surface of the water for burning a suitable fuel and blowing scorching gases along the aforementioned circulate path, thereby inflicting heat to be transferred from the surface of the outer flue member to water surrounding the latter to heat identical.

Water buy alpha heater of the sort 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 opposite 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 could circulate through the aforementioned heating chamber between the alternative open ends of the jacket. I Figure three is a cross sectional view of the flue assembly of a water alpha heater price, but illustrates yet another embodiment of the invention. Sixteen fabricated of a suitable steel and having axially opposite 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 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 within the drawing. 22 is repeatedly heated and the combustion gases are exhausted into the atmosphere by way of the annular exhaust opening 46 formed between the upper open ends 18 and 24 of the inside 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 suitable means such as. 54 are welded between the outer flue member and the higher end of the water jacket to assist the latter in axially spaced relation to the buoyant member or donut 12 in order that your entire water jacket is submerged. Water jacket 48 defines with the outer flue member 22 an annular Water heating chamber 56 by which water may circulate as it is heated.

48 and fins fifty four may be eradicated if desired and as shown, whereas the alpha heater portable further comprises an annular plate fifty eight secured between the upper ends 18 and 24 of the internal and official Alpha Heater site outer flue members to substantially shut the annular atmospheric exhaust opening 46, although the plate 58 includes a plurality of circumferentially spaced exhaust openings 60 for exhaust purposes. 62 are offered, each having one end 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 every stack extends past the sting of the buoyant member or donut 12 and under the floor of the water for discharge of the combustion gases and products beneath water level. 32 should not end in toxic, irritant-inflicting or otherwise objectionable merchandise of combustion for discharge into the swimming pool water and, therefore, one cause for the choice for utilizing natural or propane fuel because the fuel. 22 with a plurality of axially extending circumferentially spaced fin members sixty six which increase the realm of contact of the outer flue member with the water, thereby enhancing heat switch 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 within the embodiment of Figure 2 for the aim aforementioned. PORTABLE SUBMERSIBLE SWIMMING POOL HEATER Filed June 29, 1962 INVENTOR. AT/URIVE 6' United States Patent 3,194,229 PORTABLE SUBMERSIBLE SWIMMING POOL buy alpha heater Donald R. Borgeson, 18301 Riverside Drive, Birmingham, Mich. Fiied June 29, 1962, official Alpha Heater site Ser. No. 206,363 1 Claim. Cl. 126360) This invention relates to a submersible heater for a body of water and, particularly, to a extremely portable relatively simple and official Alpha Heater site cheap submersible buy alpha heater for swimming swimming pools. It has heretofore been acknowledged as being desirable to equip outside swimming swimming pools, official Alpha Heater site significantly in more northern climes, with heating techniques for heating the pool water within the interest of extending the swimming season to the utmost extent potential and to in any other case contribute typically to swimming comfort in the course of the season comparable to on cool evenings or even in the course of the day when unseasonably cool ambient temperatures'might happen.
