Best Hot Water Pressure Washers:

Hot water pressure washers are similar to cold water pressure washers in design and operation but are more powerful in slitting through the most willful of dirt, grime, filth, soot, and sap (without the need for chemicals).

Best Hot Water Pressure Washers of 2021

Check out the detailed reviews of the top steam pressure washers for a deeper peek into their features and advantages. For your convenience, we have included both commercial/industrial washers as well as those suitable for infrequent home use.

#1 - Easy-Kleen Professional 4000 PSI Hot Water Pressure Washer

Easy-Kleen is a Canadian, family-owned company that has been around since the 1980s. It started by manufacturing cold water pressures and over the years diversified into power tools for both commercial and household requirements. This professional hot water pressure washer is one of their flagship products and widely preferred across North America.

Pros
  • Variable heat setting from 153- to 185-degree F

  • 5 nozzles including a soap nozzle

  • Rugged, welded frame

  • 50-feet high-pressure hose

  • Electric start for easy engine start-up

Cons
  • Battery for the motor is not included (due to shipping restrictions)

Pressure Washer Review

The complexity of the entire ‘hot water pressure washing’ science can make buying a heavy-duty hot water pressure washer a task. But not when you choose Easy-Kleen, which offers an all-rounder like this 4000 PSI washer that has all the features and functions you would look for in a machine like this.

Starting with the 13-HP genuine Honda motor that has an electric start for quick startup. The motor runs on gasoline (as it’s an oil-fired unit) and is attached to a 12-volt burner for heating the water. This means you have the option to choose both hot and cold water – which is a necessity both by design and compliance.

There’s also a nozzle for soap (apart from its 4 other nozzles that provide 0- to 40-degree angles) for the perfect combination that we spoke about earlier in the introduction. Get rid of grime, oily dirt, and sappy residue from virtually any surface – whether it is a worked-up earthmover or a bobcat loader or a patio that has not been washed for months.

Best Hot Water Pressure Washers in 2021

The best part with this Easy-Kleen high-temperature pressure washer is that if the use of chemicals is restricted, you can adjust the temperature (up to 185-degree Fahrenheit) and go full-blown assault on the stubborn surfaces. We found that Easy-Kleen is a no-no only if the surface is made of plastic and looks like it won’t take extremely hot water.

The wheels are pneumatic, which make it easy to carry the washer around. But more than that it’s the rugged, powder-coated frame that we love so much. It might look frail, but it has the power to carry a 400-pound powerhouse that will last you for years.

Verdict

A strong, sturdy frame, a 13-HP Honda motor with a 12-V burner, variable temperature, and decent-size hose-wand combination are what make this Easy-Kleen machine the best hot water pressure washer overall. An all-rounder with the right functions and right price tag.

#2 - NorthStar 157310 Gas Wet Steam and Hot Water Pressure Washer

Just like Easy-Kleen, Northern Tool is also a family-owned manufacturing company (the Kotula family) that has been around for more than 40 years. Part of the ‘Make in America’ sentiment, Northern Tool is best known for its diversity as it also produces tools of other brands such as Milwaukee and STIHL.

Pros
  • High GPM of 4 allows for faster, cleaner washing

  • 6 nozzles with support for chemical and steam

  • High temperature output of up to 250-degree F

  • 50-feet rubber hose can be extended up to 150 feet

Cons
  • Has large tires but movement can be limited due to weight (600 pounds)

Pressure Washer Review

The Easy-Kleen tool is suitable for most applications and will last you for years. But if you want a bit more power and sturdiness, you can consider NorthStar 157310 by Northern Tool, the most powerful hot water pressure washer available right now. A high GPM of 4 and a heavy brass manifold that’s more than 600 pounds when filled up gives you raw energy and the true feeling of an American washing his truck or roof or patio.

But what really sets it apart is the ability to generate wet steam. Unlike what the word literally means, wet steam is a non-weighted combination of steam and hot water, which can have a great impact on oily surfaces.

Have a kitchen wall to clean off? This NorthStar hot water pressure washer for professionals will do the job in the lowest time.

We also like the convenient 6-nozzle panel where you just have to replace the type with the jet hand and you are done. Professionals will notice the nozzle for chemicals too, which is a great addition.

It has large wheels but moving around can still be a task. This is the only drawback we saw during our hours of testing.

#3 - SIMPSON MB1518 Hot Water Pressure Washer

Owned and operated by the FNA Group, Simpson is that friendly neighborhood company that exists only for one purpose: to serve you. Its hot water gas pressure washers are great for both household and commercial use and are best known for their affordability.

Best Hot Water Pressure Washers in 2021SIMPSON MB1518 Hot Water Pressure Washer

Pros
  • 5 quick-connect nozzles with soap dispenser

  • Easy to use, no-nonsense machine

  • Lighter than bigger, costlier washers

  • 1,500 PSI and 1.8 GPM are ideal for routine washing

Cons
  • Longtime running may reduce coil and pump lifespan

Pressure Washer Review

Sometimes you need an economical alternative to all the huge and feature-rich mobile hot water pressure washers. For some infrequent washing of your truck or maybe a monthly cleaning of your farmhouse walls and stable. That’s where the Simpson Mini Brute MB1518 helps.

For the price, its performance is exceptional. The 1.8 GPM and 1,500 PSI are enough to cut through most forms of dirt, thanks to the heat that is generated by the Mini Brute’s steel-enclosed coil. The welded steel construction is the best for heating purposes, which is just a minor yet welcome change in this machine, compared to the Easy-Kleen and NorthStar models above.

We also like that Simpson is easy to get in touch with. Have an issue that needs some technical assistance? Simply call the company and an official will resolve your issues in no time.

The 100-degree F heat will be enough for most routine activities at worksites, agri fleet, paint preparation, household cleaning, and commercial job sites. Let it be your first hot water tool.

#4 - NorthStar 157305 Electric Wet Steam and Hot Water Pressure Washer

Another machine from Northern Tool, this time a hot water pressure washer for entry-level use.

Best Hot Water Pressure Washers in 2021NorthStar 157305 Wet Steam and Hot Water Portable Pressure Power Washer

Pros
  • Simple mechanism with electric start

  • 5-nozzle support (for steam and chemicals)

  • 1,700 PSI and 1.5 GPM

  • Highest temperature of 250-degree F

Cons
  • Heavy at 385 pounds

Pressure Washer Review

Compare this with the Simpson model above and you will see one major difference: the nozzles. The 157305 can produce wet steam and can also be used with chemicals, thanks to its injector. We love that NorthStar has taken everything into consideration even in an entry-level model like this one. Oftentimes, it is just the omission of certain functions and features when you pay less.

The PSI of 1,700 is enough to cut through most forms of grime and dirt on any surface. Just use the correct nozzle and temperature to suit the surface’s needs. The 1.5 GPM is ideal for most household and jobsite removals. You may need to use soap and wet steam to get rid of oily sap or year-long build-ups on any surface. But NorthStar’s long hose and jet-stream ability of its hand are enough to take care of most of your needs.

The Leeson engine is as good as a Honda or Kohler. It’s efficient, high-power, and will last you for years. Overall, this is a top-rated electric hot water pressure washer that’s easy on your pocket and still takes care of most of your household and commercial needs.

#5 - AR Blue Clean AR630 Hot Water Pressure Washer

Annovi Reverberi is the world’s largest manufacturer of pressure washer pumps and an Italian company. AR North America (ARNA) is its American subsidiary, and this model AR630 is one of the most affordable hot water pressure washers on the market.

Best Hot Water Pressure Washers in 2021
AR Blue Clean AR630 Hot Water Pressure Washer

Pros
  • Trigger gun with TSS for better efficiency and safety

  • Lightweight at 62 pounds

  • 1,900 max PSI and 2.1 GPM is better than the industry average in this price range

  • Adjustable pressure with no lower limit

Cons
  • Jet wand is not customizable

Pressure Washer Review

Although this small hot water pressure washer is marketed as the cheapest or the most affordable, it has some excellent features up its sleeve. For example, the Total Stop System (TSS) is its biggest advantage, which ensures that the water flow is switched off when not triggered.

Moreover, the small form factor (it just weighs about 60 pounds) is bound to have a lot of takers. Compare it with the machines above that are up to 600 pounds and you clearly can see the advantage of owning a tool that’s 10x lighter and compact.

It uses an electric motor and uses a direct water supply to provide a high temperature of up to 180-degree F. While the wand is intuitive enough, we did find some issues while attaching the accessories to it. You may have to invest in a better wand for long-term use.

Also, the 2.1 GPM and 1,900 PSI are far better than the above last two models on this list. The fact that there is no minimum pressure means that you can also use it for other forms of cleaning. Lastly, the brass build is what sets it apart from the AR620 which is made of aluminum. Brass, as you know, lasts longer.

Hot Water Pressure Washer FAQs

Simple answers to some of the most commonly asked questions about commercial hot water pressure washers:

What is the difference between a steam cleaner and a hot water pressure washer?

Steam cleaners use small quantities of water to generate steam, which then cleans the surfaces. Moreover, their wand/cleaner touches the surface that is to be cleaned. They are mostly used for indoor cleaning and washing of surfaces such as tiles, floors, etc.

On the other hand, hot water high-pressure washers use large quantities of water and depend on heat and pressure to cut through dirt. They are sprayed usually from a distance of one foot, and can also be used with soap, detergent foam, and chemicals to improve their ability to clean harder surfaces.

What are the benefits of using a hot water pressure washer?

They provide the best wash output and can cut through even the hardest grime from a variety of surfaces. Hot water is beneficial for those applications where you cannot use chemicals or where the dirt has oily content.

When do you need to use a hot water pressure washer?

Hot water pressure washers can be used to remove dirt, grime, and sap that are stubborn. They can also be used on any surface (that can withstand high temperature). Common applications include truck cleaning, tire washing, jobsite washing, industrial machinery upkeep, and patio and external wall washing.

In steam pressure washers, does gasoline run both the pump and the heater?

No. In an electric pressure washer, gasoline is mostly used to run the heater. The pump works on power derived from a main socket.

Should I buy or rent a hot water pressure washer?

If you have one-time use such as yearly home cleaning, then it would be wise to rent one. On the other hand, if you have periodic use or need it for your commercial jobsite, buying makes more sense.

When renting, do compare the cost of doing so with that of a low-cost pressure cleaner such as the NorthStar 157305 and the AR630. We believe buying an affordable model might be a better case if you own a house.

What are the things to consider when buying a hot water pressure washer?

You may consider the maximum pressure and temperature settings, type and brand of the motor, efficiency of the heater/burner, nozzle type and ease, weight, and warranty. Any additional features that make your job easier could also be considered.

What are some additional features to look for in a pressure washer?

You may look for the Total Stop System (TSS), powder coating of the manifold/frame, chemical injector and soap dispenser, pneumatic tires, and a customizable jet wand. A quick look at the accessories provided by the manufacturer may also help.

How does a hot water pressure washer work?

A hot water pressure works on the same principle of a power washer with the only difference being the heated water. Tap water enters the heater through a hose which then gets heated and flown to the output via a pump. The combination of heat and pressure is what helps you cut through even the most stubborn of dirt and muck.

How to maintain the hot water pressure washer?

Maintenance basics include storing your washer in an enclosure in a basement/garage when not in use, wiping water droplets or dust from the manifold, emptying the gas tank when not in use for a long period, oiling the motor regularly, and following the instruction manual carefully before initial use.

Will hot water ruin a pressure washer?

No. Hot water pressure washers use heat-resistant wands and hoses to avoid wear and tear. Moreover, each and every element of such a washer is tested for the heated water. However, using hot water in a cold pressure washer can damage it.

Can I use cold water in a hot water pressure washer?

Yes. All good-quality hot water pressure washers have a burner switch (or thermostat) to toggle between cold and hot water.

Can I run the pressure washer without water?

No.
