An improved gas-fired water heater is disclosed which comprises a sealed cylindrical shell extending from the base of the water tank to the top, enclosing the burners and controls so as to shield them from flammable vapors in the immediate vicinity. The cylindrical shell forms an annular passage outside the tank (and insulation, if present), which facilitates the intake of combustion air. This annular passage is shielded from above and the side adjacent the top of the tank by a cover fitted to the tank top which extends downward from the top to form a lip which laterally shields the annular passage and directs intake combustion air upward from outside the shell to enter the annular passage. The bottom of the heater can be extended by a cylindrical skirt extension which encloses the burner of the heater in an airtight manner except for air inlets in the bottom of the extension.

A method according to claim 12, including the step of conducting exhaust air occurring during the drying and/or during the vaporization through at least one filter that reduces or removes odors and/or dust, and then releasing the exhaust air into the atmosphere. 14. A method according to claim 13, including the step of disinfecting at least one partial current of the stall exhaust air before or after its use for drying the feces and/or for vaporizing the liquid portion of the urine, and thereafter said partial current of the stall exhaust air is used immediately for the aeration of the urine, for the oxidation and/or disinfection thereof. 15. An apparatus for disposing of excrement, made up of feces and urine, of animals kept in a stall comprising: a separating apparatus for a separation of deposited excrement into urine and feces, separate carry-off paths leading out of the stall for a separate carrying off of the urine and of the feces, at least one separate storage and further treatment apparatus for the urine and for the feces, the apparatus for the further treatment of the feces comprising a device for the surface enlargement and drying of the feces, to a moisture content that prevents a decomposition, at which moisture content the feces can be stored and transported, the apparatus for the further treatment of the urine comprising at least one of a vaporization device and a drying device in which the liquid portion of the urine can be vaporized and the remaining solid substance can be dried, wherein one of a single exhaust air filter and a common exhaust air filter is connected downstream from at least one of the drying device and the vaporization device. 16. An apparatus according to claim 15, wherein the apparatus for the further treatment of the feces additionally comprises a pressing device for the production of pressed fecal pieces, having a residual moisture content that prevents a decomposition, from feces that is first dried in the drying device only to a moisture content of between approximately 10 and 25% by weight. 17. An apparatus according to claim 16, wherein the pressing device is a pelleting device or a briquetting device. 18. An apparatus according to claim 15, wherein the stall comprises at least one excrement deposition surface having a gradient, in whose deepest region at least one urine collection canal runs, whereby the gradient is maximally of a magnitude such that after deposition, the feces remains lying securely on the deposition surface, and the deposition surface is equipped with a mechanical device for carrying off feces, with which the feces is carried off in a direction of conveyance that deviates from the direction of the gradient, and with the maintenance of a distance from the urine collection canal. 19. An apparatus according to claim 18, wherein the stall is constructed with a slatted floor at least over a part of its floor surface, and the excrement deposition surface is the floor surface of a canal arranged underneath the slatted floor, and gaps of the slatted floor and the direction of the gradient run essentially parallel to one another. 20. An apparatus according to claim 18, wherein the device for carrying off feces is formed by a feces blade that is moved parallel to the urine collection conduit. 21. An apparatus according to claim 18, wherein for the formation of the device for carrying off feces, the deposition surface is constructed as a conveyor that is moved parallel or transverse to the urine collection canal, whereby the conveyors comprise a closed or perforated surface. 22. An apparatus according to claim 15, wherein one of a mixing device and dusting device, with which the feces can be one of impregnated and dusted with a dry powdered di
