115 volt, 8-10 GPM Diesel Fired Hot Box - 99115V

Turn Cold Water Pressure Washers into Hot Water Beasts

The BE Power Equipment 99115V Vertical Electric-Ignition Diesel-Fired Hot Box is built for professionals who need serious hot water performance without investing in a full hot water pressure washer. Designed to connect directly to an existing cold water pressure washer, the 99115V instantly upgrades your system with industrial-grade heat for faster, more effective cleaning.

Engineered for high-flow applications, this hot box supports 8.0–10.0 GPM, making it ideal for large-volume washing where heat and water flow work together to break down grease, oil, and heavy buildup. Powered by 115VAC and delivering 420,000 BTU, the 99115V heats water up to 93°C / 200°F, dramatically improving cleaning efficiency while reducing detergent usage.

Built into a rugged powder-coated steel frame, this vertical hot box is designed to withstand demanding job sites while providing reliable, on-demand hot water whenever the job calls for it.

Add Industrial Heat to High-Flow Pressure Washers

The 99115V is purpose-built for professionals running higher-GPM cold water systems and is ideal for:

• Fleet and heavy equipment washing

• Agricultural and farm equipment cleaning

• Industrial wash bays

• Property maintenance and sanitation

• Construction and transportation applications

By introducing heat into the cleaning process, operators can clean faster, cut through grease more effectively, and minimize chemical use.
