According to the present invention, a hot water type heating apparatus includes a heat exchanger and a flow quantity control valve which controls a quantity of hot water to the heat exchanger. The flow quantity control valve includes a valve housing provided with a first inlet pipe to which the hot water flows, a first outlet pipe which returns hot water to an engine, a second outlet pipe which directs the hot water to the heat exchanger, a second inlet pipe to which the hot water from the heat exchanger flows and a bypass circuit which selectively connects the hot water from the first inlet pipe directly with the first outlet pipe, and a valve body for adjusting an opening area between the first inlet pipe and the second outlet pipe. The first inlet pipe and the first outlet pipe extend from a passenger compartment of a vehicle to an engine room thereof, thereby simplifying the work for connecting these pipes.
