PURPOSE:To increase the thermal efficiency of a water heater, by inserting a pressurized fuel injection nozzle into a pressurized gas combustion chamber provided at the end of a pressurized air pipe, and by punching a plurality of pressurized combustion gas injection ports on the combustion chamber. CONSTITUTION:A compressed air nozzle 1' is provided at the end of a pressurized air pipe 1. A Pressurized fuel injection nozzle 3 is inserted into the nozzle 1'. The compressed air nozzle 1' is enclosed by a pressurized gas combustion chamber 2, and pressurized fuel gas injection ports 4 are formed by boring a plurality of through holes on the wall of a chamber 2. The pressurized air pipe 1 is connected to a blower, a compressor, or a compressed air receiver, while the pressurized fuel injection nozzle 3 is connected to a liquid fuel tank such as a kerosene tank by a tube 5 interposed by a fuel pump 6. An automatically remote-controlled ignition device is provided in the combustion chamber 2. A burner is so constituted that thermal efficiency is increased by decreasing diffusion of combustion heat, and fuel can be saved by shortening the time to heat water, by directly inserting a burner into a water tank 7 under the water and by burning fuel on the submersible burner.
