The invention discloses a heating system using municipal heat-supply one-time net backwater as a heat source. The heating system using municipal heat-supply one-time net backwater as the heat source utilizes one-time net backwater of an original city large-scale central heating system or combined heat and power generation heating system as the heat source, and collects heat energy from the one-time net backwater to produce 35-55 DEG C of water used for meeting heat supply requirements, so that heat energy is provided for terminals using heat. On the premise of not changing the heating capacity of the original large-scale central heating system or combined heat and power generation heating system one-time net pipe network system (pipe diameter, water recirculation rate, supply water temperature), heat energy of the one-time net backwater is collected and a certain electric energy is consumed to supply heat, so that the heating capacity of the original large-scale central heating system or combined heat and power generation heating system can be increased by 50% on the basis of the original heating capacity. According to the heating system using municipal heat-supply one-time net backwater as the heat source, heat supply radius of the original central heating system is extended, so that the heat supply range is enlarged, and a combined type central heating system which uses the original central heating system as a main heat source and uses 'the heating system using municipal heat-supply one-time net backwater as heat the source' as an auxiliary heat source is formed.
