3072 Instantaneous Water Heater, giving instantly a continuous supply of water 

 at any temperature, from boiling to lukewarm, free from the products 

 of combustion, and suitable for all purposes. Designed to hang over 

 lavatory bowl or sink. In two sizes; large size, height 19 inches, 

 projection from wall 8 inches; small size, height 18 inches, projec- 

 tion from wall 6 inches. This water heater is more especially in- 

 tended for the lavatory and the general odd work of laboratory and 

 domestic purposes where hot water is constantly wanted quickly. 

 The gas supply should be from a 5^-inch pipe. It will work equally 

 well, but at a proportionately slower rate, with any gas supply, how- 

 ever small. The speed at which the water runs rules its temperature. 

 It will heat 1 pint of water per minute from 50 to 130 degrees Fahren- 

 heit, or will boil 15 quarts per hour. The duty of the larger size is 

 about double that above given. It is not designed for baths. Con- 

 sumption of gas: large size, 40; small size, 20 feet per hour. 



Note. The light must be applied to the gauze before the gas is 

 turned. 



Recent Improvements. A pilot light attachment, which auto- 

 matically lights the burner when the gas is turned on; also a coupled 

 gas and water tap, operated by a hand-wheel, a turn of which lights 

 the burner and gives an immediate flow of warm water.
