<p>A heating system for vehicles which does not require a considerable space for installation in an engine compartment, can be manufactured at low cost and adequately heat a compartment at the engine start. A water pump (WP) and a viscous heater (VH) are housed in, for example, a mount housing (1) joined to a cylinder block of an engine, a plate (2) and a cover (3), and are driven by a drive shaft (11) of a common use.
