A first flow passage (R1) in which uncombusted gas (G1) that contains a combustible fuel is injected from a nozzle hole that is smaller than the flame quenching distance at a flow speed to thereby enable flame maintenance is combusted, and thereby enables flow of combustion gas (G2) resulting from such combustion, and a second flow passage (R2) formed about the first flow passage and enabling flow of uncombusted gas supplied through the nozzle hole are provided. According to the present invention, the combustion chamber in a heating apparatus that heats a liquid to be heated is be reduced in size, the flame in the combustion chamber can be stabilized, and energy efficiency can be improved.
