Pressure Washer Hot Boxes
Pressure washer hot boxes are inline water heating systems designed to turn a cold water pressure washer into a hot water cleaning machine. Installed between the pressure washer and the spray gun or hose system, a hot box heats water as it flows through the unit, giving contractors the added cleaning power of hot water without needing to replace their existing pressure washer.
Hot water pressure washer hot boxes are ideal for removing grease, oil, grime, road film, heavy equipment buildup, agricultural residue, and industrial dirt faster and more efficiently than cold water alone. By increasing water temperature, these systems help break down stubborn contaminants, reduce chemical usage, improve rinse performance, and speed up cleaning on demanding commercial jobs.
Our selection of pressure washer hot boxes includes diesel-fired inline heating units built for professional and industrial cleaning applications. These units are commonly used with truck-mounted and trailer-mounted pressure washing systems for fleet washing, concrete cleaning, heavy equipment cleaning, farm and agricultural cleaning, shop wash bays, and oil or grease removal.
Whether you are upgrading a cold water pressure washer or building a mobile cleaning rig, an inline hot box is a powerful way to add hot water performance while keeping the pressure washer you already own.

Why Add a Hot Box to Your Pressure Washer?
