Title:
HEAT SOURCE DEVICE
Document Type and Number:
Japanese Patent JP2017156034
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source device capable of preventing an abnormal sound from being generated and also securing a desired hot water temperature when supplying air for combustion to a hot water burner and a heating burner with one fan.SOLUTION: A controller 20 confirms whether to perform heating full combustion when receiving a hot water full combustion instruction. For the heating full combustion, the controller 20 closes a heating capability changeover valve 44S to stop combustion of two unit burners 4a of a heating burner block 4-2S connected to the heating capability changeover valve 44S, and switches a combustion range of a heating burner 4-2 to "in combustion range". The controller 20 performs control to start hot water full combustion. On determining that a hot water full combustion time passes 30 seconds, the controller 20 opens the heating capability changeover valve 44S to start combustion of the two unit burners 4a of the heating burner block 4-2S connected to the heating capability changeover valve 44S, and switches the combustion range of the heating burner 4-2 to "large combustion range".SELECTED DRAWING: Figure 3
