Is a Hot Water Pressure Washer Worth It?

What are the main benefits of choosing a hot water pressure washer, especially one that also works with cold water?

  • Hot water can more easily blast away dirt and keep it away. It’s quicker at cleaning surfaces than cold water is.
  • Hot water works better with detergent, particularly on greasy build-up. This makes it great for cleaning driveways and garage floors.
  • Hot water takes the elbow grease out of many jobs, making it a whole lot easier to blast away dirt.

How to Choose the Best Hot Water Pressure Washer

Before we get into the nitty-gritty details you should consider when buying a hot water pressure washer, please note that these are designed for commercial use.

These appliances are expensive, super high power, and very hot — so they’re not ideal for pressure washing around the house. Plus, your home driveway, garage floor, and other surfaces probably don’t need scalding hot water. Normal pressure will work just fine.

These pressure washers are mostly aimed at people getting paid to pressure wash. A hot water pressure washer will get you through jobs quicker. Just know that you’ll need some health and safety training for using one.

Cost

First up, the cost is worth spending a lot of time thinking over. These power tools are not cheap. However, they do come in a range of prices, but we’re talking in the thousands. Consider your budget, and try to stick to it where possible.

Portability

Consider how easy it is to maneuver. Is it on wheels? Easy to push around? How heavy is it?

Type

You’ll find both gas and electric hot water pressure washers. Electric ones are more eco-friendly and don’t require the use of gasoline. But gas pressure washers are more powerful, so if you need a high PSI, you may want to consider a gas pressure washer.

Heating System

Consider how the power tool heats up the water. This is usually either a burner or a heating coil.

A burner supplies heat and is very common in gas pressure washers. It can raise temperatures of the incoming water bringing it up to 250°F. Some can even provide steam cleaning.

Heating coils work a bit differently. They are made of pipes or tubing and are visible on your appliance. These work to heat your water up, too, but they may not always have the same power as burners do.

Can You Use Cold Water in a Hot Water Pressure Washer?

Many hot water pressures allow you to use both cold and hot water. Some have a dial that lets you control the temperature. If that sounds like something you’d like, definitely look for one that has this feature.

Water Pressure

Check the PSI of the appliance. This measures the amount of pressure per square inch. The higher this number, the more powerful the pressure washer is.

Also, consider GPM — gallons per minute. The higher this is, the more water can go through the machine at a time. This gives you more force when cleaning.

Some may advertise their pressure on cleaning power — CP. This is achieved by multiplying the PSI with the GPM.

If a machine has 4000 PSI and four GPM, then the CP is 16,000.

Safety

Because these are powerful machines, it’s a good idea to choose one with some nice safety features. This could include a shut-off switch on the trigger gun, a safety valve for using low pressure, a safety lock to prevent accidental uses, and much more.

Extra Features

What extra features does the pressure washer come with? These could be wands, spray guns, hoses, nozzles, and other attachments. These features could help you have more control over your pressure washer.

Hours of research have gone into creating this list of the best hot water pressure washers. We’ve looked at real customer reviews, expert advice and applied our own insight. Soon enough, you’ll find a pressure washer that delivers heat, power, and ultimate cleanliness!

1. NorthStar Electric Portable Pressure Power Washer

Best Electric Hot Water Pressure Washer

Fight all kinds of dirt with this portable electric pressure washer from NorthStar.

It can reach temperatures of 250°F, so it can also steam clean. This allows you to sanitize surfaces to get rid of germs without the use of disinfectants or harsh chemicals.

This durable hot water pressure washer, set up on a sturdy and portable frame, is one that you’ll love having around. It will take your cleaning routine to the next level.

Why We Love It

Provides Quick Cleaning

As fun as pressure washing can be, no one wants to spend all day doing it. Thankfully, this tool can speed up your cleaning routine. Grime, grease, and oil are no match for this device. The power of hot water and high steam can blast through the toughest dirt and grease in no time.

High-Efficiency Leeson Motor

This comes with a Leeson electric motor which is specially designed for hot water tools. This allows it to handle high temperatures and allows for a dynamically balanced rotor. This leads to low vibration and high-efficiency to save you energy.

Durable Design

This is a durable device that should last for years to come. It uses a Cat pump for high-performance and a long lifespan. Combined with high-end ceramic plungers to provide resistance to corrosion and abrasion, the pump life on this is designed to withstand rigorous use.

Keep In Mind

Loud Whine

You may notice a loud whine to the pump. This doesn’t seem to be a common problem but it’s something to point out as it could get annoying.

Soap Injector Issues

A few customers called out the soap injector, saying that it has never worked correctly, even after buying a new kit. Keep this in mind, and contact the manufacturer if you notice any issues.

2. Northstar Electric Commercial Pressure Washer

Best Steam Hot Water Pressure Washer

Utilize the power of steam cleaning by choosing this electric commercial pressure washer from North Star.

This upgrades your cold water into hot water or steam which gives you the ultimate clean of your surfaces.

Plus, steam sanitizes and disinfects without the use of harsh chemicals. So if you’re worried about germs, bacteria, mold, and mildew — this is a top choice!

Why We Love It

Reaches 250°F

The diesel burner in this industrial model heats water up to 250°F which is hot enough to melt grease, grime, and oil quickly and efficiently. Spend less time cleaning and more time relaxing when you choose something this powerful.

No More Interruptions

There’s nothing more annoying when pressure washing than having to stop a million times to top up the fuel, give the hose a rest, or something else.

This device allows you to say goodbye to interruptions. The extended-run four-gallon tank lets you work for a long time without stopping for fuel.

The connections are also fast and easy to use which keeps the flow of your cleaning going.

Choose Your Own Temperature

Choose your own temperature with the handy temperature control. If you don’t want to go all the way up to 250 degrees, you don’t have to. This gives you more control over the tasks at hand.

Keep In Mind

Hard to Move

This comes with a sturdy frame and a handle for portability, but that doesn’t make it easy. Why? Because the wheels are too short. The bottom of the pressure washer gets stuck on the ground at times, making it very difficult to move. It could do with some bigger wheels.

Repair Galore

Quite a few customers had to order in repairs or send the product away for repairs. Hopefully, this doesn’t happen to you but do keep in mind that a few people experienced issues.

Additional Specs

Portability Short wheels make portability hard; 253 pounds
Type Electric
Heating System Schedule 80 heating coil

3. Easy-Kleen Professional 4000 PSI Pressure Washer

Best Portable Hot Water Pressure Washer

Portability is key, especially with these heavy machines. This pressure washer from Easy-Kleen weighs 400 pounds, which is a lot. But on this sturdy and four-wheel frame, it’s one of the easier high-power portable pressure washers to maneuver.

The handles at the front mean you can easily push and pull it with you where you want to go. The thick wheels allow it to navigate over different types of terrain, too.

Why We Love It

13 HP Honda Engine

With the 13 horsepower Honda commercial-grade engine, this is unbeatable power and reliability. It has an electric start which makes it easy to get up and running. Plus, it’s quiet and very durable.

Please Note

The battery is not included so you will need to purchase this separately.
Schedule 80 Heating Coil

The heating coil on this power tool can bring the water up to 150°F over the existing temperature. So if your water is coming in at 65 degrees, this can bring it up to 215 degrees. The complete ceramic seal blanket over the coils allows for efficiency, quick heat up time, and fuel-saving. Lastly, it works really well in cold climates!

Professional Grade Spray Gun

People often forget the importance of a quality spray gun. With this one, you’re really getting your money’s worth! It comes with five quick-connect nozzles of varying degrees. Plus, it provides 50 feet of high pressure! This lets you cover a lot of ground at once and work in a wide area.

Keep In Mind

Failing Seals

You might find that the seals on the connecting points aren’t of the highest quality. This can result in leaks. The manufacturer doesn’t have a lot of information in the user manual on how to correct or replace this.

Additional Specs

Portability Sturdy frame and wheels; 400 pounds
Type Gas with electric start
Heating System Schedule 80 heating coil
PSI 4000
GPM 3.5

4. NorthStar Gas Hot Water Pressure Washer

Best Gas Hot Water Pressure Washer

Looking for a gas option? These are great if you want a higher PSI. With a PSI of 3000, this comes with unmatched power for heavy-duty and commercial cleaning.

Being gas, it has two 8.75 gallon tanks. They’re color-coded for your understanding, too. Red for gasoline, and yellow for diesel, fuel oil, or kerosene. Keep in mind this has an electric start, but it runs on gas.

Overall, this is an awesome pressure washer that provides both hot water and steam up to 250°F.

Why We Love It

3000 PSI

With a PSI of 3000, anything is possible with this gas hot water pressure washer. This is strong enough to blast off all kinds of stubborn dirt from a huge range of surfaces.

Honda Engine

What benefits does the Honda engine give this pressure washer? Firstly, this device is always prepared for the task at hand. The commercial-grade engines also mean it’s super reliable, easy to start, and very powerful. Last but not least, it also has improved fuel efficiency, a longer run time, and perhaps best of all — quiet operation.

Reliable Machinery

When spending this much money, you want something that’s going to be reliable — and this is it. It’s kitted out with a state-of-the-art Cat triplex pump which aids its dependability. The pump’s direct-drive design uses fewer moving parts which cut down on maintenance but maximizes value.

Keep In Mind

Extremely Heavy

Without fuel, this unit weighs 600 pounds. Add fuel and you’re talking even heavier. This decreases the ease of portability, which is a struggle for many customers.

Hard to Maintain Hot Water

Firstly, it can take around 10 minutes for the hot water to come in which is inconvenient. Secondly, it’s hard to maintain the hot water. A few customers reported that the burners are very strong and can damage the charging coil. So you’ll need to check and replace the battery quite often.

Additional Specs

Portability Sturdy frame and wheels; but it weighs 600 pounds

5. Ar Annovi Reverberi AR630-HOT Pressure Washer

Best Affordable Hot Water Pressure Washer

Hot water pressure washers are very expensive, but this is a pretty affordable competitor compared to other options.

This little guy can reach temperatures of 180°F which will be enough to deep clean grease, grime, and other dirt.

It has a maximum PSI of 1900. So it’s actually one of the only options on our list that is more suited to home use than commercial.

However, you can definitely still take it to work and see awesome results.

Keep In Mind

This is not on any sort of portable frame, so it’s a bit of a hassle to maneuver. However, you could set a frame up yourself for sure!

Why We Love It

Serious Safety Features

Safety comes first with this pressure washer. The trigger gun helps you determine when it’s definitely switched off, giving you peace of mind. You can also lock the trigger to avoid accidental sprays. Lastly, it automatically shuts down when it detects electrical ground failure.

Adjustable Pressure Gauge

Choose your own PSI with the adjustable pressure gauge. This is ideal since different surfaces require a different PSI. For instance, you may want a different PSI when washing a bike versus a driveway.

Mesh Water Filter

This comes with a mesh-designed water filter which makes the device super easy to clean. Overall, this extends the life of the pump so you can get years out of the product.

Keep In Mind

Not On Wheels

One of the biggest drawbacks of this appliance is that it’s not on wheels. This makes it very difficult to maneuver and takes some of the practicality away from this option.

No Attachments

Due to the adjustable pressure gauge, this doesn’t come with nozzles or the option to attach any nozzles. If you’re used to this, this machine may require a bit of a learning curve. A few customers were put off by this.

Additional Specs

Portability Not on wheels; 69 pounds
Type Corded electric
Heating System You need to heat the water first
PSI 1900
GPM 2.1

6. Steel Dragon Tools Hot Cold Pressure Washer

Best Powerful Hot Water Pressure Washer

Want something with a high PSI? If you’re on the hunt for something powerful, this is pretty unmatched.

The Steel Dragon Tools pressure washer has a PSI of 4000 and an amazing GPM of 21! That’s going to give you some incredible power when you’re pressure washing.

It also allows hot water up to 210°F as well as the use of cold water when you’d rather use that. Overall, this gives you versatility and control over your tasks.

Why We Love It

Versatile

You can use this for a variety of jobs. This includes parking lots, decks, patios, sidewalks, driveways, pool tiles & decks, and much more. It’s best for commercial work due to the high power, but it can still tackle a range of duties.

59 Pounds

Compared to some of our other recommendations which are often up to 600 pounds heavy, this is a lovely little lightweight option. It only weighs 59 pounds due to the plastic frame so it’s easy to maneuver (though maybe not as durable).

Range of PSI

While this has a maximum PSI of 4000, it has a minimum PSI of 1250, making this a super duper versatile product. You can use it for home use or commercial. The lighter pressure allows you to use this on house siding and cars without causing any damage.

Keep In Mind

Plastic Housing

Most of our other recommendations have a sturdy steel frame that is durable and rust-resistant. However, this plastic one is a little bit cheaper, less durable, and more subject to damage.

Additional Specs

Portability On wheels; 59 pounds
Type Gas
Heating System Not specified
PSI 4000
GPM 21

7. Simpson MB1518 Hot Water Pressure Washer

Best Durable Hot Water Pressure Washer

Thanks to the welded steel frame and powder-coated finish, this pressure washer is highly durable and corrosion-resistant. If you’re looking for something that’s built to last, then the Simpson MB1518 is one to consider.

The motor is also highly reliable. It is a 120-volt heavy-duty induction motor system engine with a triple-A triplex pump to give your machine a powerful edge.

Why We Love It

Long Convenient Spray Gun

We think you’ll like this spray gun. It’s 48 inches long, so it allows you to get into hard-to-reach places and tight corners. It’s also finished with an insulated grip for maximum comfort and control.

13-Inch Tires

The 13-inch pneumatic tires are heavy-duty and strong. They provide great portability and can easily travel across different terrain types.

Versatile Functions

This pressure washer is designed for use on worksites, agricultural fleets, paint prep areas, and commercial job sites. While it isn’t intended for home use, it still has a lot of purposes.

Keep In Mind

1500 PSI

For a commercial, gas-powered, pressure washer, the PSI is quite low. At 1500, this matches the average electric pressure washers used for the house. We don’t recommend it for home use, since the manufacturer hasn’t specified that. However, it may not be strong enough for some commercial tasks.

Additional Specs

Portability On 13 inch wheels; 255 pounds

Heating System Diesel fired burner
PSI 1500

Tips for Maintaining Your Hot Water Pressure Washer

You’re about to spend a lot of money on a hot water pressure washer, so it’s important to take care of it. Here are our top maintenance tips:

  • Don’t leave your pressure washer turned on for more than three minutes when you’re not spraying it. This can damage the pump and you may require a replacement. Always turn off the machine if you are going to step away from it.
  • Always check the pump and engine oil levels before each use.
  • Drain moisture from the heating coil regularly. There should be a drain valve on the boiler. Leave it open for a while, at least once a week, to rid any moisture residue.
  • Always remember to turn off the heater before you stop spraying water. This ensures that only cool water flows out at the end. It also protects the metal part of your sprayer wand and allows the heating coils inside the cool down before you store the pressure washer.
  • If you’re planning to store your pressure washer away for a couple of weeks, or longer, drain out the water and chemical systems. Fill the machine with anti-freeze. Next time you go to use it, it will be in mint condition.
  • Once a month, check the air filter to make sure it isn’t clogged with dust or dirt. You will likely need to replace the filter every six months.
  • Change the engine oil every 100 hours of work or every three months. Only use oil that the manufacturer recommended.
  • Change the pump oil when you get the machine and replace the pump oil every 250 hours of work, or every three months.
  • Replace the burner fuel filter every three to six months.
  • If you find condensation or water in the fuel tank, drain the tank and leave it open for a little while.

Bonus Tip

While these are 10 important tips, there are many more to consider. Make sure to read the user manual that comes with your hot water pressure washer thoroughly to know all the important maintenance tips for your model.
