Abstract
A generally cylindrical housing containing a burner underlying a fluid conduit formed to provide a plurality of interconnected concentric helical coils, the outermost coil having a lower end portion projection below the lower ends of the inner coils. A reticulate baffle, in underlying engagement with the lower end of an inner coil, cooperates with the lower end portion of the outermost coil to define a combustion chamber, the baffle permitting flow of gases of combustion upwardly therethrough but retaining most of the burner flame within the combustion chamber. The fluid conduit and its mounting structure are arranged for easy removal from the housing and replacement therein.
Claims9
A water heater comprising:
- a. a housing including a base portion, a cylindrical body portion, and an upper end member defining an opening for removal of gases of combustion;
- b. a burner disposed at said base portion and disposed to direct a combustion flame upwardly in said housing;
- c. a rigid fluid conduit in said housing;
- d. means for supporting said conduit above the level of said burner;
- e. said conduit being formed to provide an interconnected plurality of concentric helical coils including an outer coil of relatively long axial length and an inner second coil of relatively shorter axial length within said outer coil, said second coil having an upper end disposed near the upper end of said outer coil;
- f. a generally horizontally disposed reticulate baffle having a diameter slightly less than the inner diameter of said outer coil;
- g. and means for supporting said baffle within said outer coil at the lower end of said second coil;
- h. said baffle and the lower end portion of said outer coil cooperating with said burner to define a combustion chamber, said baffle being operative to permit flow of gases of combustion upwardly therethrough while retaining the greater portion of the burner flame within the combustion chamber.
