PURPOSE:To save fuel consumption and permit to use the heater without any anxiety by a method wherein water, passing through a fine tube for heat transfer having good heat conducting efficiency, is preheated during passing through a heating chamber, heated sufficiently by high-temperature flon gas in a high-paressure enclosed vessel and receives heat transferred through the outer wall of the high-pressure enclosed vessel in hot-water collecting section. CONSTITUTION:The high-pressure enclosed vessel A is filled with heat transfer medium gas F, such as flon gas or the like, through a gas charge F and a part of the vessel A is partitioned to define the heating chamber D while the heater E is provided to heat the gas F and gasify it into high-temperature gaseous body. The fine tube B for heat transfer passes at first through the heating chamber D and is arranged in the high- pressure enclosed vessel so as to have a coil-like arrangement or the like having necessary and sufficient length for the transfer of heat, then, is introduced into the hot-water collecting section K between a tank C and the vessel A. Water, entered from a water supplying port I, is preheated in the heating chamber D, heated sufficiently in the high-pressure enclosed vessel A and is collected in the hot-water collecting section K as hot-water, keeping a high temperature under receiving heat transferred through the wall of the vessel A. A safety valve is attached to the high-pressure enclosed vessel to secure the safety thereof. |
