Abstract:
1. A portable boiler for a heating mat comprising: a water reservoir storing circulating water that is received through an inlet tube disposed on one side of an upper portion of the water reservoir; a heat-transfer part allowing the circulating water to flow along a flow passage to exchange heat and discharging the circulating water to a heating mat through an outlet tube disposed on one side of the heat-transfer part; a heating part for heating the circulating water inside the heat-transfer part by burning fuel gas supplied from a fuel tank; a housing defining an exterior of the portable boiler; a heat-collecting plate on an undersurface of the heat-transfer part to increase thermal conductivity, wherein the water reservoir comprises: wherein the heat-transfer part has the flow passage that allows the circulating water to absorb heat when the check valve is opened and the circulating water flows therein; wherein the heating part comprises: wherein the flow passage of the heat-transfer part comprises: wherein the portable boiler further comprises a shield plate disposed between the inclination flow passage and the bypass flow passage of the heat-transfer part to prevent heat transferred from the heat-collecting plate from being transferred to the water reservoir through the flow passage.
