<p>The present invention relates to a boiler for a hot water mat. According to the present invention, the boiler for a hot water mat comprises: a water tank which stores water to supply the water to a mat in which a tube is installed to provide a passage of water; a heating tube which is provided between the water tank and the tube and heats the water discharged from the water tank; and a bubble discharging means which discharges bubbles, generated by heating the water, to the outside of the water tank. The bubble discharging means includes: a pressure chamber which is arranged in the water tank to provide a route of bubble flowing backward in the water tank, includes a second accommodating space separated from the first accommodating space accommodating water in the water tank, and changes the level of water in the second accommodating space depending on whether bubbles are discharged to the outside of the water tank or introduced into the inside of the water tank; and a buoyancy unit which is installed in the pressure chamber to be vertically lifted and is lifted according to the level of the water and selectively discharge the bubble introduced into the pressure chamber by the lifting motion.</p> |
