<P>PROBLEM TO BE SOLVED: To provide a latent heat recovery type hot-water supply system capable of starting a combustion operation by quickly bringing a storage container into a water-sealing state even when combustion is required during a time when the liquid is refilled to keep the storage container in the water-sealing state. <P>SOLUTION: This hot-water supply system 1 has a neutralizing device 7. The neutralizing device 7 is provided with the storage container 30 capable of storing drainage, and the drainage and the water supplied through a water injection pipe conduit 41 are stored therein to keep the water-sealing state. A faucet 28a is opened when the water is injected into the storage container 30 through the water injection pipe conduit 41, openings of a bypass water amount regulating valve 48b and a hot water supply amount regulating valve 49a are throttled when the amount of water flowing toward the faucet 28a is over a prescribed amount, so that the water is injected to the storage container 30 with priority. <P>COPYRIGHT: (C)2009,JPO&INPIT |
