One of the biggest choices when buying a Kränzle is whether to go for a hot water or cold water machine. It is an important decision, because it affects both performance and price. The good news is that the right answer is usually clear once you understand the difference. Here is how to choose.
The simple difference
A cold water pressure washer cleans using pressure and flow alone. A hot water machine heats the water as well, and that heat makes a real difference on certain types of dirt.
Think of it like washing up. Cold water shifts everyday dirt, but for greasy, baked-on mess, hot water cuts through far faster. The same principle applies to pressure washing.
What cold water does well
A cold water Kränzle handles the vast majority of everyday cleaning brilliantly:
- Washing cars and vehicles.
- Cleaning patios, driveways and decking.
- Removing mud, dust and general dirt.
- Garden furniture and outdoor surfaces.
For most homeowners, and many professionals, a cold water machine is all you will ever need. It is simpler, more affordable, and perfectly capable of excellent results on general dirt.
Where hot water wins
Hot water comes into its own the moment grease and oil are involved. Heat breaks down greasy, oily, baked-on grime far faster than cold water can, and it gives a more hygienic finish.
Hot water is the better choice if you regularly clean:
- Engines, machinery and workshop floors.
- Commercial kitchens and food preparation areas.
- Heavily soiled commercial vehicles and fleets.
- Industrial equipment with oil and grease build-up.
In these situations, a hot water machine saves you time on every job, and often reduces how much chemical you need too.
The speed and chemical savings
This is the part people underestimate. On greasy work, hot water does not just clean better, it cleans faster.
A job that takes an age with cold water and lots of detergent can be far quicker with hot water doing some of the work. For a busy professional, that time saving adds up significantly over weeks and months.
The trade-offs of hot water
Hot water machines do cost more, both to buy and to run, because they need to heat the water. They are also generally larger and a little more complex.
For someone who genuinely needs hot water, that cost is easily justified by the time and results. For someone cleaning patios and cars, it is paying for capability they will rarely use. Be honest about your real cleaning needs.
How to decide
Ask yourself one question: do you regularly clean grease, oil or baked-on grime?
- No, mostly general dirt like cars, patios and gardens. A cold water Kränzle is the right, sensible choice.
- Yes, grease and oil are a regular part of the work. A hot water Kränzle will pay for itself in time and results.
If you are somewhere in between, it is worth a conversation, because the right answer depends on the balance of jobs you do.
Both come with Kränzle quality
Whichever you choose, you get the same Kränzle engineering, with brass pumps, ceramic plungers and a build designed to last. The hot or cold decision is about matching the machine to your work, not about quality. Both ranges are built to the same exacting standard.
Quick summary
-
Cold water: perfect for cars, patios, gardens and general dirt. Simpler and more affordable.
Hot water: the right choice for grease, oil and heavy industrial grime. Faster and more hygienic on tough jobs.
The deciding question: how often do you clean grease and oil?
