Abstract

PURPOSE:To automatically and efficiently prevent a liquid path from being fouled, by a method wherein detergent is fed at regular intervals into the path that passes through a latent heat recovery device, and the water level in a hot water storage is monitored constantly to supply water automatically. CONSTITUTION:Pipes 13 and 9 that are connected to a latent heat recovery device 8 are likely to be fouled by mineral oil contained in the exhaust gas supplied to the latent heat recovery device 8. However, as detergent is fed from a detergent container 19 to the latent heat recovery device 8 through a valve 20 and a fed pipe 22 at specified intervals set by a timer 21, the exhaust gas comes into contact with the detergent, and the mineral oil is dissolved into waste liquid and discharged outside through valve 18. As a result, the exhaust gas is always cleaned, so that the fluid path in the latent heat recovery device 8 is not fouled by the exhaust gas.
