Abstract
Disclosed is an air heating apparatus including a burner configured to cause a combustion reaction, a main passage, through which water flows while circulating, a heat exchanging device configured to receive heat from combustion gas generated by the combustion reaction and heat the water flowing along the main passage, a heating heat exchanger configured to receive the water heated by the heat exchanging device and exchange heat with the air for heating, a fan configured to send the air to the heating heat exchanger, and a hot water discharge port connected to the main passage such that the water heated by the heat exchanging device is discharged to an outside of the main passage.
Claims20
An air heating apparatus comprising:
- a burner configured to cause a combustion reaction;
- a main passage, through which water flows while circulating;
- a heat exchanging device configured to receive heat from combustion gas generated by the combustion reaction and heat the water flowing along the main passage;
- a heating heat exchanger configured to receive the water heated by the heat exchanging device and exchange heat with the air for heating;
- a fan configured to send the air to the heating heat exchanger to which the water heated by the heat exchanging device is received, the fan further configured to discharge the air heated by the heating heat exchanger to an outside of the air heating apparatus;
- and
- a hot water discharge port connected to the main passage such that the water heated by the heat exchanging device is discharged to an outside of the main passage.

- a hot water discharge port connected to the main passage such that the water heated by the heat exchanging device is discharged to an outside of the main passage, and
- a water inlet port communicated with the main passage such that the water is introduced into the main passage,
- wherein the main passage includes a part connecting the heating heat exchanger and an upstream side of the heat exchanging device with respect to a direction in which the water flows in the main passage, and
- wherein the water inlet port is disposed on an upstream side of a point at which the main passage and the heat exchanging device meet each other with respect to the direction in which the water flows in the main passage.
