PURPOSE: A fuel reduction heating system is provided to reduce fuel consumption by improving heating efficiency, while preventing freeze burst of the pipe during winter times. CONSTITUTION: A heating system comprises a heat exchanger block(1), a heating pipe(2), a hot water pipe(3) and circulation pumps(4,4'). The heat exchanger block includes a heating operation heat exchanger block(11) for passage of heating fluid and a main hot water heat exchanger block(12) for passage of hot water. The heating operation heat exchanger block has a flow channel formed into zig-zag shape having a predetermined width and depth. The main hot water heat exchanger block has a flow channel formed into zig-zag shape having a predetermined width and depth. The heating operation heat exchanger block and the main hot water heat exchanger block are coupled with each other through a coupling member.
