Hot vs. Cold Water Pressure Washers

For the most part, hot and cold water pressure washers achieve the same results, both can be used to clean your house, fence, car, boat, etc.

Both will clean those things in roughly the same amount of time, though there is a scenario where a hot water pressure washer just trumps a cold water pressure washer, whether it’s a medium duty or even a most powerful electric pressure washer.

Grease, fat, and oils.

When these are hit by cold water they just solidify, and while a cold water pressure washer will remove this type of dirt and grime, it’s not without a bunch of effort, you may even have to get your soap nozzle going, sometimes cold water just isn’t enough, sometimes you have to add a soap or detergent to lift the dirt and grime.

This isn’t the case with a hot water pressure washer, grease, fat, and oil all melt and moves quickly when heated, so using a hot water pressure washer just lifts that dirt away in minutes.

You save loads of time and get a proper clean from a hot water pressure washer when facing this type of dirt.

But there is a place where cold water pressure washers trumphot water pressure washers.

Price… Coldwater pressure washers are drastically cheaper.

Hot water pressure washers pros and cons

What can you clean with a hot water pressure washer

Absolutely everything you can clean with a cold water pressure washer. There are many uses for your pressure washer.

Those weeds and moss in your patio… gone…

Grease and oil in concrete.. a thing of the past.

Fences, garden furniture, decking, cars and boats, and much more all will become spotless and like new when using a hot water power washer. I don’t advise using a hot water unit against anything living, plants or grass, and the like, the hot water could well cause damage.

Hot water pressure washer buying guide

Maximum heat/burner

Make sure to check the maximum heat that your burner can produce. If you are looking to remove grease, grime, and oil, then you want something that can hit 130F (55 degrees Celsius) or higher.

If you are going to be using this in a commercial setting such as a kitchen or garage, I recommend you look for a burner that can produce 250F (120 degrees C) or higher.

These high temperatures help break down the molecular structure of grease and grime; thus, it’s easier to clean the surface.

Heating Coil

The heating coil is an essential part in heating the water, The coil is made of schedule 80 pipes or tubes. If the heating coil is made of steel, then it’ll have a long life span

Burner fuel tank size

Depending on how long you intend to be, cleaning will dictate how large a furl tank size. Typically these are between 4 and 10 gallons.

The larger the tank, the heavier the unit (when full), but then it reduces the number of times you need to refill the tank.

This only applies to gas hot water pressure washers.

Gas or electric

This comes down to your personal choices, an electric-powered hot water pressure washer is a quiet and efficient machine and offers fantastic results, there are no fumes, they are lighter than their gasoline pressure washer equivalent and require very little maintenance.

They are tied to a power outlet and will produce a lower cleaning power due to their lower PSI and GPM.

They can be used indoors, so they are perfect for use in kitchens and garages where oil and grease are rampant.

A gas-powered hot water pressure washer has no need for an electrical outlet, it can be used anywhere, where there is a water source. You just need to ensure that it’s got fuel and oil, and you’re set to go.

The cleaning power of a gasoline hot water pressure washer will dwarf that of an electric hot water pressure washer. Thanks to the gasoline engines producing much higher PSI and GPM.

So if you want high cleaning power, perhaps for cleaning concrete and the ability not to be tethered to a power outlet, then a gas hot water power washer is for you.

Work in a kitchen or garage, don’t mind the lower cleaning power, want a quiet(ish) operation, then electric is for you.

Electric Powered Hot Water Pressure Washer

Electric powered hot water pressure washers are quiet and efficient machines, offering fantastic cleaning results.

The Electric powered hot water pressure washers are usually quiet and efficient machines that offer great pressure for cleaning. As compared to the gas fuel, these types of products use the electric motor, which is very reasonable to run. The life of the product is also more, and you don’t have to do much maintenance for running.

The hot water pressure washer work at full load volumes always and needs a regular electricity supply. However, you must not use the extension cord for connecting the machine as it can reduce the available power or can result in motor failure.

Trailer or pushcart

Small hot water pressure washers will usually be cart- mounted these aren’t the most portable pressure washers, as the heating coil, burner, fuel tank, and engine increase in size. So does the size of the cart frame.

Eventually, you hit a point where it’s not practical to use a pushcart, and instead, these are trailer mounted.

You can also get wall-mounted versions such as the AR Annovi Reverberi AR630TSS-HOT Commercial Pressure Washer.

Make sure to take into consideration your needs, there’s no point buying the most powerful hot water pressure washer only to find it’s trailer-mounted, and you’ve nowhere to store it.

Heat-resistant high-pressure hose

When purchasing, you want to make sure that the hose material is made of silicone rubber, as silicone rubber is safe to use at high temperatures.

You can also use a hot water pressure washer hose that’s made of Nitrile rubber tubing. It’s a synthetic type of rubber that’s manufactured with the highest quality to resist high temperatures, chemicals, and even fuel efficiency.

Make sure it’s a high-quality hose that’s kink and marring resistant. You want your hose to last a long time as these hoses aren’t cheap.


You need to work out what you will be cleaning. If you are washing down kitchen/metal backsplashes, you don’t need a machine producing 28000 cleaning power.

However, if you are keeping a garage floor clean, removing daily built-up oil and grease well you want a high powered machine, you need to penetrate the concrete, which isn’t easy.

How to Maintain the Hot Water Pressure Washer

Hot water pressure washers require more maintenance than their cold-water counterparts.

  • Make sure to check the oil every 3 months or so and replace it with a good pump oil brand when the oil level reduces, or you come up to a scheduled oil change. You can find when you should do this in the manual.
  • Check the air filter once a month, removing any dirt and grime that might block the filter, I personally recommend replacing the air filter every six months to ensure optimum performance.
  • If the unit is going to be stored for a while, make sure to remove the fuel as stale fuel can be bad for the engine
  • The same goes for the burner fuel
  • Ensure that your heating coil is in a good state and not covered in limescale

Wrap up

For most, a hot water pressure washer won’t be required, but if you want to be able to tackle all stains, grease, oil, etc. Then nothing beats it.

These machines are expensive, but they are built to last, and a cold water pressure washer just cannot compete in the type of cleaning results you get from these machines.

Hopefully, in my hot water pressure washer reviews above, I gave you all you needed to make a decision.
