This high-performance hot water pressure washer delivers a powerful combination of 4,000 PSI and 5.5 GPM, cutting through grease, oil, grime, and buildup with professional-grade precision. Equipped with a Honda GX690 V-Twin engine, a belt-driven AR triplex pump, and a 12V Beckett burner for diesel-fired hot water up to 200°F, this machine is designed for serious cleaning performance in demanding industrial, agricultural, and commercial environments.

Ready to mount on a truck or trailer and built for continuous use, the HW4024HA12V is a rugged workhorse for teams that can’t afford to slow down.

Hot Water Cleaning That Cuts Through Anything

Not all pressure washers are built the same—and when you're working with grease, oil, or baked-on residue, cold water just won’t cut it. That’s where the HW4024HA12V shines. The 12V Beckett burner powers a robust heating coil fueled by diesel, giving you water temperatures of up to 200°F (93°C). This scalding heat breaks down contaminants fast, reduces chemical use, and speeds up your workflow.

The burner system includes a rocker switch for quick activation and an adjustable thermostat so you can tailor the heat to the task. Whether you're sanitizing equipment or blasting off stubborn residue, this washer gives you full control over the temperature.

Powered by the Honda GX690 Engine

The heart of this machine is the Honda GX690, one of the most powerful and reliable engines in Honda’s commercial lineup. This electric-start V-Twin engine is built for long hours, heavy loads, and real-world abuse. It's engineered with OHV technology, a cast iron cylinder sleeve, and a high-output charging system to ensure consistent power for both the pump and the burner system.

Every accessory included is built to match the heavy-duty performance of the washer itself.

Heavy-Duty Frame for Truck and Trailer Mounting

The HW4024HA12V is built on a 1.5" OD powder-coated steel roll cage, designed specifically for mobile installation on trucks or trailers. The frame protects the engine, pump, and burner while keeping all components accessible for operation or maintenance. Reinforced mounting brackets and a central lift point make it easy to install, secure, and relocate as needed.

Whether you’re building a mobile wash rig or adding to a fleet of industrial cleaners, this pressure washer is ready to integrate into your operation.

Designed for Easy Maintenance

Time on the job is too valuable to waste wrestling with routine service tasks. That’s why this unit includes oil drain hoses on both the engine and the pump, allowing you to perform oil changes cleanly and quickly without tipping or disassembling the frame.

From regular maintenance to emergency service, this thoughtful design helps reduce downtime and keep your equipment in top shape.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
