PURPOSE: A heating system using condensation heat is provided to improve heat energy efficiency by supplying hot water heat exchanged from a first waste heat recovery device to a second waste heat recovery device. CONSTITUTION: A heating system using condensation heat composed of first and second waste heat recovery device(21, 50), a hot water connection line(561), and a heating unit(60). The second waste heat recovery device collects the condensed sensible heat of coolant discharged from a compressor(10) and installed between a condenser(20) and the compressor. The hot water connection line connects the first and the second waste heat recovery device by supplying hot water in a first waste heat recovery device to the second waste heat recovery device for heat exchange. The heating unit produces steam by heating the hot water discharged from the second waste heat recovery device. Tap water is supplied to the first waste heat recovery device and the second waste heat recovery device receives hot water discharged from the first waste heat recovery device and the hot water outlet(571) of the second waste heat recovery device is connected to the heating unit.
