Hot water pressure cleaners are referred to by many names, including hot and cold pressure cleaners, steam cleaners and diesel fired pressure cleaners.

Cold water pressure cleaners are machines that pump cold water at a particular flowrate, depending on the size of the pump, under pressure through a nozzle for many different cleaning applications. Normally, the larger the delivery flowrate of the pump, the bigger, better and more productive the pressure cleaners are, but when you start talking about hot water pressure cleaners, this rule does not apply.

The hot water pressure cleaner reigns supreme in the stakes between cold water pressure cleaners and hot water pressure cleaners purely because the cleaning result and the time factor changes completely when using hot water. One cannot compare pressure cleaners which are the same technical specification because of the huge difference in cleaning performance when using hot water machines as compared to cold water machines.

Hot water pressure cleaners have come along way since the days of having to heat the water yourself first, then using that heated water to supply the pressure cleaner which would do the cleaning.

A hot water pressure cleaner works these days by having water pumped and pressurized through the pressure pump, the heated via a diesel petrol heater before being discharged out of the machine through the nozzle.

The heat of the hot water does most of the cleaning as compared to a cold water machine which relies solely on pressure to clean. In regards to hot water machines, the heat along with the pressure provide the strength behind the application of cleaning.

A fairly common question posed by customers looking to purchase a pressure cleaner for a specific job is, "Does hot water make that much of a difference over cold?" One cannot truly appreciate the differences in cleaning results and the speed at which it can be done unless you have used a hot water machine.

It is fair to say that this applies to a majority of cleaning applications but is not the case for all particular projects. Having said that, it is also fair to say that in the majority of cases, a hot water pressure cleaner produces a much better result regardless of the particular cleaning task compared to a cold water pressure cleaner regardless of the cold pressure cleaners water flowrate or operating pressure.

Do you generally clean your dishes in cold water, or do you set your dishwater to use cold water? Why would you think that this same principle would not apply to pressure cleaning in general?

So for large industrial applications that require removing heavy dirt, grease or other materials, hot water pressure cleaners are the clear choice to use.
