Hot water pressure washers, on the other hand, deliver a powerful jet of high-temperature water that dissolves even the most stubborn dirt even faster and more effectively than cold water models. Before passing through the pump and being dispensed via the spray gun, the water is heated by the diesel-powered boiler installed on the machine. Hot water models are used to deep clean surfaces, machinery, and equipment containing grease, oil, and stubborn food residues, ensuring excellent results thanks to the sanitising action of heat. These pressure washers are also eco friendly: the delivery of hot water jets guarantees high cleaning performance without resorting to the use of chemical detergents or, in any case, significantly limiting their use.
