A new fluid temperature control for a heated fluid cleaner with multiple outlets for maintaining the temperature of the discharge fluid when multiple outlets of the heated fluid cleaner are opened. The inventive device includes a fluid reservoir for containing a supply of fluid, at least one pump for suctioning fluid from the fluid reservoir. A heater is also in fluid communication with the pump for heating a flow of fluid received therefrom. The heater preferably comprises a combustible fuel heater and has a fuel conduit fluidly connecting the heater to a fuel reservoir. An outlet conduit is fluidly connected to the heater for receiving heated fluid therefrom. The outlet conduit has a plurality of outlets for discharging fluid therefrom. A heater control device is provided for controlling the temperature of the fluid exiting the heater such that it is maintained at a constant predetermined temperature when more than one outlet is opened.
