1. A heat exchanger disposed on a downstream side of a gas flow passage of combustion exhaust gas ejected from a burner and connected to an inlet pipe for allowing a fluid to be heated to flow in and an outlet pipe for allowing the fluid to be heated to flow out,the heat exchanger comprising a stacked body formed by stacking a plurality of heat exchange units in a gas flow passage direction of the combustion exhaust gas,wherein each of the plurality of heat exchange units includes:

  • an internal space in which the fluid to be heated flows,a plurality of gas vents penetrating the internal space in a non-communicating state and through which the combustion exhaust gas passes,at least one inlet port for allowing the fluid to be heated to flow into the internal space, andat least one outlet port for allowing the fluid to be heated to flow out from the internal space,wherein the internal spaces of adjacent heat exchange units communicate with each other via the outlet port of one heat exchange unit and the inlet port of another heat exchange unit, andthe inlet pipe and the outlet pipe are provided so as to protrude from a most downstream heat exchange unit located on a most downstream side of the gas flow passage of the combustion exhaust gas, among the plurality of heat exchange units constituting the stacked body, toward the downstream side of the gas flow passage of the combustion exhaust gas.
