Kind Code:
A
Abstract:
To provide a latent heat recovery type water heater in which piping for discharging drain water to outside of the device is eliminated.SOLUTION: A latent heat recovery type water heater includes: atomization means 40 for atomizing drain water in a drain water tank 39; an atomization air flow passage 41 through which atomization air atomized by the atomization means 40 passes; a merging section 46 disposed in an air flow passage section 30 downstream of a combustion gas of a secondary heat exchanger 27 and communicated with the atomization air flow passage 41; a branch section 31 disposed in an air flow passage section 30 on a combustion gas upstream side of the merging section 46; an air supply passage 34 communicated with the branch section 31 and an inlet of the atomization air flow passage 41; first opening/closing means 43a capable of opening/closing the atomization air flow passage 41; and a control section 60 that performs combustion control of a combustion section 8, opening/closing control of the first opening/closing means 43a and drive control of the atomization means 40. The control section 60 closes the first opening/closing means 43a during combustion, and opens the first opening/closing means 43a after stop of the combustion to drive the atomization means 40 and a combustion fan 13.SELECTED DRAWING: Figure 1
