Burner and water heating apparatus including same

A water heating apparatus comprising:

• a burner configured to cause a combustion reaction;
• and
• a heat exchanger configured to heat water flowing through the inside using the heat generated by the combustion reaction,
• wherein the burner comprises:
• a mixing chamber having therein a space in which fuel and air are mixed to form a mixture;
• a chamber lower cover that is coupled to the mixing chamber while covering an opening formed in the mixing chamber in a reference direction and has a combustion opening that is opened;
• a porous distribution unit that comprises a porous material, through which the mixture passes in the reference direction, and is located in the combustion opening;
• a distribution plate which is located in the combustion opening and through which the mixture passing through the porous distribution unit passes;
• an ignition unit located in the combustion opening to ignite the mixture that has passed through the distribution plate;
• and
• a flame temperature acquisition unit configured to acquire temperature and comprising a measurement terminal located between the porous distribution unit and the ignition unit,
• wherein the porous distribution unit, the distribution plate, and the ignition unit are arranged in the reference direction.
