PURPOSE: An apparatus for heating a heating space of a vinyl house, etc. by heating a first fluid to circulate along a first circulating flow path arranged in the heating space and allowing for heat exchange between the first fluid and a second fluid which have different specific heats on a circulating flow path to circulate the first fluid in the heating space while maintaining above a set temperature is provided. It enables uniform heating of the heating space and increases heat efficiency and heating efficiency. CONSTITUTION: The heating apparatus heats a heating space by heating a first fluid and circulating along a first circulating flow path(62,64) arranged in the heating space. The apparatus is characterized in that it comprises: a case installed on one side of the heating space to divide a first and second circulating space(54,56) in which two different first and second fluids are circulated; the first and second circulating flow path installed on the outside of the case to connect with the first and second circulating space and circulate the first and second fluid; a combustion means(70) installed in the case to heat the first and second fluid; a heat exchange means(80) for maintaining the first fluid at proper temperature or more in the heating space by allowing for heat exchange between the first fluid and second fluid even if heat loss from the first fluid becomes large as the first circulating flow path becomes long. |
