A vehicle heating system comprising: a coolant circuit that circulates coolant between an engine and a heater core; heating device that heats coolant, which is interposed in the coolant circuit; a pump for coolant circulation, which is interposed in the coolant circuit; and a switching valve that switches the coolant flowing through the coolant circuit between a heater-core-side circuit that circuits the coolant among the heater core, the pump and the heating device and an engine-side circuit that circulates the coolant into the engine, wherein the switching valve has a thermo valve that switches channels so that the coolant coming from the engine-side circuit enters either one of the heater-core-side circuit and the engine-side circuit according to temperature of the coolant, and a bypass that delivers the coolant, which comes from the heater-core-side circuit, to the heater-core-side circuit.
