Heating water.-A boiler for providing a supply of hot water at constant temperature below boiling-point consists of a water-containing vessel A heated continuously by a burner H and having a sheet M of non-corrodible metal, such as nickel chromium alloy, fixed in, upon, or just below its copper bottom L in the region of the flame, and means such as a ball cock D for allowing water to flow slowly into the vessel at a fixed predetermined rate. The size of the flame is so fixed that the temperature of the water can never rise above, say 150‹ F. Water flows in at such a rate that the vessel is filled in about 20 hours. Specification 152,721 is referred to.
