Transform your cold water pressure washer into a hot water cleaning system with professional hot boxes and burner units designed for commercial applications. Our selection includes stationary and portable hot boxes from BE and Pressure Pro that deliver the heat needed to cut through grease, oil, and heavy buildup that cold water alone cannot remove.

Whether you're adding heat to an existing cold water pressure washer or replacing a worn burner unit, hot boxes provide the cleaning power needed for restaurant equipment, industrial machinery, automotive parts, and oil and grease removal from concrete. Hot water cuts through grease and oil faster, sanitizes surfaces, and reduces cleaning time while using less detergent. All hot boxes feature diesel fuel systems with electric ignition for reliable operation in demanding commercial environments.
