With that in mind, hot water pressure washers are designed for applications needing extra cleaning power, like commercial kitchens or construction yards. To help you find the right one, I've compiled this list of the best hot water pressure washers. Check out my criteria for selecting these pressure washers below.

Take the compact, gas-powered Hot2Go SH4000SHH hot water pressure washer wherever you need to clean tough stains or grease. It provides 4,000 PSI of water pressure at 3.5 GPM of flow with both hot water and wet steam cleaning capability. 

Great for restaurant and food processing applications, the Hot2Go cleans at up to 250° F thanks to an 8-gallon diesel- or kerosene-fueled burner and a durable, stainless-steel-wrapped heating coil made with Schedule 80 steel piping. That is hotter water than what many other power washers can provide. The 12-volt DC igniter includes a charging circuit to maintain steady heat. 

The AR Triplex ceramic plunger pump is designed to run cool and last long. Adjust the water pressure as needed depending on your job. It’s all powered by a reliable Honda GX390cc engine that includes an electric start and low-oil alert feature. 

You’ll get three quick-connect spray tips (the spray gun and hose connections are also quick-connect). Among them is a 25° wide steam nozzle for the saturated steam spray cleaning. The four wheels and lifting point make moving the Hot2Go simple between and around job sites. Plus, integrated storage hooks keep the hose and gun organized. 

Overall, this is a fantastic, compact unit for your hot water pressure washing needs. Enjoy a 5-year warranty on the pump and a 3-year Honda warranty on the engine.

I’m talking about 3,500 PSI of hot water pressure at 8 GPM of flow that will easily conquer a variety of municipal, mining, forestry, and industrial cleaning jobs. A 26-horsepower Kohler engine with electric start powers the unit.

Structural bracing and a lack of seam welds in the pipe reduce vibration and boost longevity. The coil sits inside a stainless steel housing and is sealed with a ceramic blanket that conserves heat. You can control and adjust the temperature on the oil-fired burners with an on-off switch and adjustable thermostat. 

The heavy-duty triplex plunger pump allows you to adjust the water pressure as needed and is belt-driven, which lets it handle long-lasting jobs with ease. Adding to durability is an all-welded frame.

How We Picked the Best Hot Water Pressure Washers

When recommending hot water pressure washers, we take four features into account. 

 

Durability

Hot water pressure washers are typically commercial grade, so they need to effectively handle heavy usage and unforgiving environments. 

One of the first things I look at is the frame. The material, thickness, and number of welding points all play a role in how much abuse the pressure washer can handle. For example, having a powder-coated finish will help the pressure washer resist rusting in corrosive environments. 

Inside, I look at the construction of the pistons, valves, and, most of all, the heat exchanger. Since the whole point of these units is hot water, the heat exchanger should be well-protected and designed for longevity.  

I also look at the engine and pump. Is it a reputable brand? Does it run cool and efficiently? Will it handle years of use? Safety and comfort features, like low oil alerts and a high temperature limit switch, are another consideration. 

Overall, every component should be built to last, including the hose, belt on a belt-drive unit, and wheels/tires if applicable. 

 

Usability

Using your pressure washer should be as simple and frictionless as possible. This is where I look at anything that makes life easier for you, the user.   

Since many hot water pressure washers are very large due to their heavy-duty design and power, you need options to get them to the job site. For example, having forklift holes can make a world of difference when trying to place a 1,600 Ib pressure washer in the back of your truck. 

Other features like electric start, quick-connect fittings, built-in hose reels, and maintenance accessibility help remove roadblocks from operating and maintaining your pressure washer, so you can spend more time being productive.

 

Versatility

It’s important to be able to adapt your pressure washer to the job at hand. That’s where versatility comes into play. 

For me, adjustable pressure reigns supreme when choosing a pressure washer. Your jobs could vary day to day, so you need to be able to adjust the water pressure accordingly. Using too high of a pressure can ruin some surfaces, but using too low of a pressure might not clean well enough on others.  

Since we’re looking at hot water pressure washer specifically, the ability to adjust the temperature is another important consideration. Some units also include a hot water tank, giving you the freedom to work longer without a refill. 

Hose length is another factor because the object you're cleaning may not always be conveniently located next to your pickup truck. Some units even include a water tank, so you can be self-sufficient in the field.

 

Overall Value

You get what you pay for. Sure, there are cases when you can get a great deal on a quality pressure washer, but it usually costs money and resources for manufacturers to make their product “the best.” 

That’s why I don’t exclusively consider price when determining value. It’s a factor, but not the most important one. I'm most interested in whether the pressure washer is worth the price. Do its durability, usability, and versatility features justify the purchase? This is also where I consider the warranty and where the pressure washer is made.

Hot Water Pressure Washer FAQs 

When should I use a hot water pressure washer?

Hot water pressure washers are designed to clean greasy or oily surfaces. While cold water is sufficient for breaking up general dirt or grime, it won't be as effective on grease or oil, even if used with detergent.

That's why hot water power washers are most common in the food processing, oil, automotive, and construction industries. For example, a restaurant facility manager might use high-pressure hot water to clean and help disinfect greasy kitchen equipment. Or, an autoshop owner might use hot water with detergent to remove a stubborn oil stain from the garage floor. 

 

Do hot water pressure washers also handle cold water applications?

All hot water pressure washers are also cold water pressure washers. If you leave the burner off, you'll be cleaning with cold water, which is all you might need for common dirt surfaces. Note that the opposite is not true. If you run hot water through a pressure washer designed only for cold water, you could damage or destroy it. 

 

What are steam pressure washer nozzles used for?

Steam can be extremely effective against the toughest grease and oil stains when all other water options have failed. The higher temperature of the steam is perfect for clearing gum from a sidewalk, cleaning grease traps in a restaurant, or gently cleansing delicate surfaces like monuments and historic buildings that might otherwise be damaged by water.
