A gas booster is provided to improve thermal efficiency by optimally using combustion heat generated in a gas combustion part of a heater part. A gas booster is composed of a gas heater(100) and a waste heat recovery system(200). The gas heater is composed of a heater part(110) and a hot water storage(120). Inside the heater part, a gas burner and a plurality of heat exchange pipes(111) are installed. A plurality of heat exchange pipes are connected to the hot water storage. The waste heat recovery system is composed of first, second and third waste heat recovery parts(210,220,230). Each waste heat recovery part is comprised of an outer reservoir(211,221,231) and exhaust gas passage parts(212,222,232). Inside the exhaust gas passage part, a plurality of heat recovery pipes(213,223,233) are installed. A plurality of heat recovery pipes are connected to the outer reservoir respectively. |
