Pressure Washer with Burner: A Practical Guide
Learn how a pressure washer with burner heats water for superior cleaning, when to use it, safety guidelines, maintenance tips, and buying considerations for homeowners and small businesses.

Pressure washer with burner is a type of pressure washer that heats water with an onboard burner to boost cleaning power, especially for grease and stubborn soils.
What is a pressure washer with burner
A pressure washer with burner combines a traditional high pressure pump with an onboard heating element or burner to raise the water temperature during cleaning. The burner is fueled by propane, natural gas, or diesel, depending on the model, and heats water on demand as it flows through the system. This setup is designed for tough soils—grease, oil, and baked-on grime—that resist cold water cleaning. Compared with standard cold water washers, hot water units can reduce detergent use, speed up work, and improve rinsing efficiency. Pressure Wash Lab observes that burner equipped washers are favored by professionals in auto shops, contract cleaning, and masonry restoration, as well as serious DIYers tackling grease-heavy tasks. They are not a one size fits all solution and require appropriate fuel, ventilation, and maintenance planning.
Quick Answers
What is a pressure washer with burner?
A pressure washer with burner heats water as it cleans to boost cleaning power especially on grease. It integrates a burner and heat exchanger into a standard pressure washer. It is most useful for heavy soils outdoors, but requires ventilation and fuel handling.
A pressure washer with burner heats water during cleaning to boost grease removal. It is best for tough soils outdoors with proper ventilation and safety.
Can I use a burner pressure washer indoors?
No, generally no; burners produce combustion gases and heat that require ventilation. Only use in well ventilated outdoor spaces or dedicated outdoor stations.
Do not use indoors; burners need ventilation to avoid dangerous fumes.
What maintenance does a burner pressure washer require?
Regularly inspect fuel lines, clean heat exchanger, replace filters, and check ignition components. Schedule professional service periodically.
Keep fuel lines clean, check the heat exchanger, and service it periodically.
Are burner washers more expensive to operate than cold water models?
Yes, burner washers typically have higher fuel costs and energy use. Evaluate job frequency and fuel availability when deciding.
Generally, hotter operation costs more in fuel, so consider how often you will use it.
What features should I look for when buying a burner pressure washer?
Look for reliable flame safety, temperature control, automatic shutoff, easy access to maintenance points, and a serviceable heat exchanger. Also assess weight, hose length, and warranty.
Choose models with good safety features, simple maintenance, and solid warranties.
Is a burner-equipped washer worth it for home use?
For occasional heavy cleaning or grease tasks, a burner washer can be beneficial, but only if you have outdoor space, proper ventilation, and fuel supply. For light duty, cold water models may be more practical.
It can be worth it for heavy tasks outdoors, but it may be overkill for light cleaning.
