Abstract

PURPOSE:To enable to heat water to supply the hot water by utilizing the radiated heat of a burner by a method wherein a heating tube is provided at the inside of a barrier provided so as to encircle the burner for a cooking stove by constituting in the manner so that the outlet of the heating tube is positioned higher than the inlet thereof. CONSTITUTION:Upon heating the hot-water, a cock 27 is opened firstly to introduce the water from city-water tube 28 into the spiral heating tube 15 through a connecting pipe 24, subsequently the water is supplied into a reservoir 21 through the second connectingly pipe 26 to reserve it to a predetermined water level. In this condition, the cock 27 is closed while a cock 23 is opened, the burner 6 for the cooking stove 1 is ignited and a cooking pot 32 is heated to make cooking. Then, the heating tube 15 is heated directly by flames (b) ejected from nozzles 4 opened diagonally while is heated indirectly by the heat reflected by the barrier 12. Consequently, heated water is sent to the upper part of the reservoir 21 from the outlet 20 of the heating tube located at a position higher than the inlet 19 thereof while the low-temperature water in the reservoir 21 is introduced into the heating tube 15 through the inlet 19 thereby rising the temperature of the water in the reservoir 21.
