<p>PURPOSE:To improve the stability of effluent hot-water by constructing a title hot-water boiler including an air exhaust mechanism at the top of a closed hot-water storage tank. CONSTITUTION:Bubbles produced during heating by a hot-water heater 7 are stored at the top 3 in a hot-water storage tank 2. There is provided an air exhaust mechanism 4, so that the mechanism 4 can exhaust the bubbles stored at the top 3 to the outside of the hot-water storage tank 2 without causing those bubbles to flow out from a hot-water outlet 8 to a downstream side. Accordingly, the bubbles can be prevented from interrupting the operation of a pump 9 and hence effluent hot-water from a faucet 10 and the like can further be stabilized. The air exhaust mechanism 4 may be constructed by directly mounting a relief valve 5 on the top 3 of the hot-water storage tank 2, or in case where exhausted bubbles are desired to be guided to another place, one end of a pipe 6 may be connected with the top 3 of the hot-water storage tank 2 to communicate with each other, and the relief valve 5 may be mounted on the other end of the pipe 6.</p> |
