PURPOSE: A heating apparatus in which a part of a heating pipe which is installed horizontally on both ends around the outer peripheral surface of a water tank is curvedly formed to minimize thermal strain rates in the axial direction during thermal strain. Therefore, it prevents the breakage of a seaming portion between the heating pipe and water tank even though the water tank and heating pipe are heated and increases heating efficiency. CONSTITUTION: The heating apparatus is installed on one side of a heating space of a vinyl house, etc. to maintain the heating space at above proper temperature by heating a heat transfer fluid(W) when the outside temperature is low like winter days, The heating apparatus consists of: a water tank(54) for allowing the heat transfer fluid to flow in a case(52); a heating pipe(56) installed in the water tank; a combustion means(60) installed on one side of the heating pipe to heat the heat transfer fluid by heating the heating pipe; and a circulating flow path(58) disposed in the heating space of the outside of the case to heat the heating space by allowing the heated heat transfer fluid to flow, wherein the heating pipe is formed curvedly on both ends connected to the water tank to prevent the breakage of a seaming portion between the heating pipe and water tank by minimizing thermal strain rates in the axial direction of the heating pipe during thermal strain. |
