Overview

This is a stationary 12-volt add-on hot box that converts any brand-name 4–5 GPM cold water pressure washer into a hot water machine. A diesel-fired Beckett burner heats the water through a super-efficient schedule 80 coil wrapped in stainless steel, with an adjustable thermostat for temperature control and a safety pressure relief valve. Fuel comes from the built-in 8-gallon poly diesel tank with fuel filter, all mounted on a rugged powder-coated steel frame. Your pressure washer needs a high-output charging system, since the 12-volt burner requires a 20-amp continuous power supply (not included). It's the practical way to get hot water cleaning power — grease, oil, fleet washing — without replacing a cold water machine you already own. Not for sale in California.

Frequently asked questions

Yes — it's built to add hot water to any brand-name 4–5 GPM cold water pressure washer, as long as the machine's engine has a high-output charging system to run the 12-volt burner. You plumb the hot box inline between your machine and the gun, so no other modification is needed.

The burner requires a 20-amp continuous 12-volt power supply, which is not included. On most setups that power comes from the pressure washer engine's charging system, which is why a high-output charging system on your cold water machine is required.

The Beckett burner is diesel-fired, and an 8-gallon poly diesel fuel tank with a fuel filter is built into the unit, so you don't need to add a separate fuel supply.

No — this model is not for sale in California. If you're in California, call APS and we can point you to a compliant hot water option.
