A cleaning system includes a liquid heating system utilizing heat from the cooling air and the exhaust gases of an internal combustion engine. A heat pump driven by the engine is utilized to extract heat from the cooling air and impart that heat to a first heat exchanger. A second heat exchanger is associated with the exhaust gases for extracting heat therefrom. Liquid to be heated is conveyed through said first and second heat exchangers.
