Title:
HEAT SOURCE MACHINE
Document Type and Number:
Japanese Patent JP2015129601
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source machine capable of preventing freezing of a drain path and capable of reducing power consumption.SOLUTION: A heat source machine can recover latent heat of a combustion gas and includes: a burner 2; a secondary heat exchanger 5; a drain path 6; a temperature detection unit 7; a drain path heating unit 8; and a control unit 9. The heat source machine is configured in such a manner that, when the temperature detection unit 7 has detected a temperature equal to or less than a predetermined temperature, and when the burner 2 is supplying a combustion gas, only in the case where the control unit 9 determines that there is drain in the drain path 6, the drain path heating unit 8 heats the drain path 6.
