Abstract
Abstract A water heater and distiller apparatus is provided in which condensing steam is the distilling portion of the apparatus giving up its latent heat to water which is being heated in the water heating portion of the apparatus. In a preferred embodiment, products of combustion which are used to boil water in the distiller boiler, are later passed in heat exchange relation with the water heating tank in the water heating portion of apparatus. It is believed that the present apparatus is both energy efficient and uncomplicated as compared to the prior art.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
374 words
A water heater and distiller apparatus adapted for utilizing latent heat of water condensing in a distilling process for heating water, said water heater and distiller apparatus comprising: a boiler chamber means for containing water to be boiled to steam, said boiler chamber means having an inlet for receiving water from a water supply and an outlet disposed for delivery of steam thereout said boiler chamber being closed except for said inlet and said outlet; heating means for boiling water in said boiler chamber means; a water heating tank means for containing water to be heated, said water heating tank means having an inlet for receiving water from a water supply and an outlet for passage of heated water thereout; a condenser means disposed for being cooled by water in said water heating tank means, said condenser means having an inlet for receiving steam, an outlet for delivery of condensate thereout and means for collection of condensate from said outlet and arranged such that said condensate is removed for use separate from said boiler chamber means; duct means communicating with said outlet of said boiler chamber means and said inlet of said condenser means for delivery of steam from said boiler chamber means to said condenser means; a reservoir disposed laterally of said boiler chamber means, said reservoir being open to air pressure; flow control means for controlling the flow of water from said reservoir for maintaining the level of water in said boiler chamber means below a predetermined maximum and above a predetermined minimum, said flow control means comprising a float valve controlled by a float, said float valve being adapted for closing upon said level of water moving to said predetermined maximum and adapted for opening upon moving of said water level to said predetermined minimum; conduit means communicating between said boiler chamber means and said reservoir for communicating water from said reservoir to said boiler chamber means, at least a portion of the length of said conduit means being disposed entirely downwardly of said predetermined minimum so as to form a gas trap for impeding venting of steam from said boiler chamber means through said conduit; and heating means separate from said condenser means for heating said water to be heated.
Claim 2
Dependent Claim
374 words
A water heater and distiller apparatus adapted for utilizing latent heat of water condensing in a distilling process for heating water, said water heater and distiller apparatus comprising: a boiler chamber means for containing water to be boiled to steam, said boiler chamber means having an inlet for receiving water from a water supply and an outlet disposed for delivery of steam thereout said boiler chamber being closed except for said inlet and said outlet; heating means for boiling water in said boiler chamber means; a water heating tank means for containing water to be heated, said water heating tank means having an inlet for receiving water from a water supply and an outlet for passage of heated water thereout; a condenser means disposed for being cooled by water in said water heating tank means, said condenser means having an inlet for receiving steam, an outlet for delivery of condensate thereout and means for collection of condensate from said outlet and arranged such that said condensate is removed for use separate from said boiler chamber means; duct means communicating with said outlet of said boiler chamber means and said inlet of said condenser means for delivery of steam from said boiler chamber means to said condenser means; a reservoir disposed laterally of said boiler chamber means, said reservoir being open to air pressure; flow control means for controlling the flow of water from said reservoir for maintaining the level of water in said boiler chamber means below a predetermined maximum and above a predetermined minimum, said flow control means comprising a float valve controlled by a float, said float valve being adapted for closing upon said level of water moving to said predetermined maximum and adapted for opening upon moving of said water level to said predetermined minimum; conduit means communicating between said boiler chamber means and said reservoir for communicating water from said reservoir to said boiler chamber means, at least a portion of the length of said conduit means being disposed entirely downwardly of said predetermined minimum so as to form a gas trap for impeding venting of steam from said boiler chamber means through said conduit; and heating means separate from said condenser means for heating said water to be heated.
Claim 3
Dependent Claim
91 words
A water heater and distiller apparatus, as claimed in claim 1, wherein said heating means for boiling water in said boiler chamber means includes a gas burner disposed in relation to said boiler chamber means whereby products of combustion from said gas burner will flow in heat-exchange relationship with said boiler chamber means upon ignition of said gas burner; and wherein said gas burner is disposed in relation to said water heating tank means whereby said products of combustion will subsequently flow in heat-exchange relationship with said water heating tank means.
Claim 4
Dependent Claim
64 words
A water heater and distiller apparatus, as claimed in claim 2 wherein said water heater and distiller apparatus includes a combustion chamber, and wherein said boiler chamber means and said gas burner are disposed within said combustion chamber, said gas burner being disposed downwardly of said boiler chamber means and wherein said combustion chamber is in heat-exchange relationship and said water heating tank means.
Claim 5
Dependent Claim
74 words
A water heater and distiller apparatus as claimed in claim 2 wherein said water heater and distiller apparatus includes a second gas burner disposed for supplying heat to said water heating tank means, said second gas burner being disposed in relation to said water heating tank means whereby products of combustion of said second gas burner will flow in heat-exchange relationship with said water heating tank means upon ignition of said second gas burner.
Claim 6
Dependent Claim
111 words
A water heater and distiller apparatus, as claimed in claim 4 wherein said water heater and distiller apparatus includes a combustion chamber, and wherein said boiler chamber means and said gas burner are disposed within said combustion chamber, said gas burner being disposed downwardly of said boiler chamber means and wherein said combustion chamber is in heat-exchange relationship with said water heating tank means and wherein an upper surface of said combustion chamber is in heat-exchange relationship with said water heating tank means and wherein said second gas burner is disposed in said combustion chamber downwardly of said upper surface of said combustion chamber and upwardly of said boiler chamber means.
Claim 7
Dependent Claim
51 words
A water heater and distiller apparatus, as claimed in claim 3, wherein said water heater and distiller apparatus includes at least one flue extending from said combustion chamber through said water heating tank means for delivery of said products of combustion therethrough in heat-exchange relationship with said water heating tank means.
Claim 8
Dependent Claim
111 words
A water heating and distiller apparatus, as claimed in claim 6 wherein said water heating and distilling apparatus includes a gas-to-liquid heat exchanger, said heat exchanger including a gas passage having a gas inlet and a gas outlet and said heat exchanger including a liquid passage having a liquid inlet and a liquid outlet; supply conduit means for delivery of water from said water supply to said liquid inlet of said heat-exchanger and from said liquid outlet of said heat exchanger to said water heating tank means; and exhaust duct means for delivery of products of combustion from said at least one flue to said gas inlet of said heat exchanger.
