The Kranzle Hot Water Pressure washer is a worldwide product and the company preach ‘Better Perfect…Than Cheap’ and that certainly rings true with this product.

The pressure, much like others is adjustable between 30-130 BAR so slightly higher than some of the most popular brand hot water pressure washers.

The water flow output is a huge 660 litres per hour making any job a short process. 

A downside to this unit is that it only tops out at a maximum temperature of 82°C, not a problem if you are looking for a slightly smaller hot water pressure washer suitable for home use. 

It includes all the other comforts you would expect to recieve from a high end pressure washer including a 15m hose and on board storage.

This extra machinery does come with a price though, and that’s the weight. This power washer weighs nearly 150kg, making it the heaviest of this list.

You can expect a huge 200 BAR of pressure and an even larger 1260 litres per hour of water flow rate. This is up there with the largest we have ever seen for a pressure washer.

With a maximum temperature of 155°C this unit by the popular brand Karcher can easily remove any stubborn dirt or grime and is perfect for removing, oily, greasy patches. 

With the ability to go so hot it creates a lot of risks as well. Be sure to never shoot the water at another person or car paint. The temperature can be adjusted for the type of job you are carrying out and you can reduce it down to 80°C for more delicate jobs. 

The variable pressure you can expect from this unit is between 30-120 BAR, not the highest and certainly not as high as some petrol pressure washers but teamed with the heated water it does a great job at cleaning patios and driveways too.

All you need to know about Hot water pressure washers

What are hot water pressure washers used for?

Hot water pressure washers are a step up from a petrol or electric one. 

You can get ones that are electric that you plug in or more likely diesel powered. Generally the most common place youll find a hot water pressure washer is in a van mounted set up. They usually work the same as any other pressure washer but implement the use of a boiler which heats the water. 

Hot water pressure washers are better for removing hard to clear stains, chewing gum, greasy or oily marks and also sanitising. Generally you’ll get a slightly better result and be able to use a lower pressure to get that finished look looking awesome. 

But you do encounter a much higher price tag with a hot water unit, due to the expensive boiler set up, buying one can really hurt the pockets. 

How hot are hot water pressure washers?

Hot water pressure washers can range in their max temperature.

The lowest we have seen, or that you would want to buy is around 90°C and the max being around 155°C. The hotter the water the better equipped it will be to soften congealed oil and food grease.

This makes a hot water pressure washer great for cleaning industrial food warehouses.

why are hot water pressure washers so expensive?

Hot water pressure washers are considerably more expensive than their electric and in most cased their petrol counterparts.

This is simply because hot water requires a boiler, so not only are you paying for your pressure washer you are paying for a boiler added on as well.

 This can also increase the upkeep cost of the unit as yearly maintenance and checks will be essential to a long-lasting machine.

How to winterize hot water pressure washers?

Winterising a hot water unit is pretty straight forward. We have linked a video below that you can watch if it makes it easier. But if not, here are the steps to winterize your hot water pressure washer.

  1. Empty all the water out of the unit
  2. Add the anti-freeze or winterizing liquid.
  3. Turn on the unit and slowing pull the trigger and release in order to push the liquid through the unit hitting all the internal areas.

Add some anti-freeze to the detergent tank to make sure that is protected too.

What is the best hot water pressure washer?

Choosing the best hot water pressure washer can be difficult and ultimately depends on what you want to use it for.

Despite hot water pressure washers being so expensive, they actually aren’t all great in the pressure department. With pressure ranges starting from as little as 110 bar and ranging up to 200+ bar for the heavy duty, high priced units.

A great use for a hot water pressure washer is for cleaning a fleet of vehicles. They normally offer a much larger water flow per hour so cleaning large jobs that allow for hot water to be used can be completed much quicker than a traditional pressure washer.

How to build a hot water pressure washer?

There are few deep web posts that claim to be able to show you have to make your own hot water pressure washer. We wouldn’t strongly advise that you don’t try and make you own.

Due to them consisting of boilers, and other highly complicated components there are a lot of dangerous parts of building one and should be left to the professional manufacturing companies.

Why use hot water pressure washer?

Hot water will clean slightly better than cold water. The heat from the water is better at melting congealed oil and food fats which makes it great for cleaning industrial food warehouses.

Hot water will also dry quicker so using it to clean cars or a fleet of vehicles makes short work with a hot water pressure washer.

Finding used hot water pressure washers for sale

There are several places you can go too to find used hot water pressure washers for sale. 

eBay is a great place to search for any pre-owned items and you’ll find several used and new ones on their site.

Gumtree is great for selling old items locally and you can find hot water pressure washers along with loads of other items too.

Facebook marketplace is another place you can go too to find cheap deals on used hot water pressure washers, just be sure to check it’s all working as Facebook marketplace doesn’t have a returns policy.
