Overview

This is a 12VDC stationary hot box that adds thermostat-controlled hot water to any pressure washer flowing 8 to 10 GPM. Plumb your existing cold-water machine through it and the flow switch fires the burner automatically whenever water is moving, while the PAC inline adjustable thermostat holds your target temperature. Water heats through a Schedule 80 black pipe coil mounted in a black powder-coated industrial-grade frame, with a safety relief valve protecting the system and a 7-gallon poly fuel tank with gauge feeding the burner. Hot water is the right tool for grease, oil, road film, de-icing, thawing, and ready-mix make-up water — jobs cold water alone won't cut. Note: the 8 GPM 12V SDC burner requires a 20-amp charging system, and this unit is not for sale in California.

Frequently asked questions

Yes — it's a stand-alone add-on that works with any pressure washer flowing 8 to 10 GPM. You route your machine's output through the hot box's heating coil, so no modification to the washer itself is required.

The burner runs on 12VDC, and the 8 GPM 12V SDC burner requires a 20-amp charging system. Make sure the vehicle or engine powering the unit can supply that charging capacity before installation.

A flow switch controls the burner, so it only fires when water is actually flowing through the coil. The PAC inline adjustable thermostat then regulates the outlet temperature, and a safety relief valve protects the system.

No — this hot box is not for sale in California. If you're in California, contact APS to discuss a compliant hot-water option for your setup.
