Hot Pressure Washers

For many general cleaning jobs cold water will be adequate, however if what you are cleaning has any level of grease or oil then it is a hot water machine that you require.

Most hot pressure washers achieve hot water by pumping cold water through a double wound coil where a flame is fired down the centre, of course this is all self contained in the item that is commonly known as the pressure washer “boiler”. The flame itself is created by atomising diesel through a burner nozzle and then supplying an ignition source. All the user has to do is turn on a burner switch, set the thermostat to the desired temperature, pull the trigger as normal and in a very short space of time there will be hot water emerging from the nozzle.

Industrial Pressure Washers

Picking the Right Hot Pressure Washer

In some instances the use of a flame or the fumes that can be produced as a result of the diesel burning process in many hot pressure washers is not permitted - such as inside large factories where ventilation is a concern. In this scenario an electrically heated machine or a LPG heated machine can be used to achieve similar results, although not as efficient these types of machines can still produce reasonable temperatures when used correctly.

The vast majority of hot water pressure washers use an electric motor driven high pressure pump to send the water through the boiler, however totally self contained engine driven hot water machines can be supplied on request allowing the user to be completely mobile.

The use of hot water not only produces a higher standard of cleaning but can also make some tasks up to 50% faster, saving on labour and allowing more jobs to be done!

Choose Britclean for Commerical Pressure Washers

As with all pressure washers the options can sometimes seem a little daunting, should you choose a high ( 2800 rpm ) or low revving ( 1450 rpm ) machine, should you opt for pressure or flow, 240 volt or 415 volt? If your budget will allow then always choose a low revving motor and pump which will increase the lifespan of the machine and a low revving pump will also be much better at drawing its own water from a container should you require it. As for pressure and flow, for most general cleaning tasks a good balance of both is required – an industrial 240 volt machine will operate at around 100 bar with a flow rate of 11 litres per minute, if you need more than this then you should be looking at a 415 volt machine or possibly engine driven. It is also important to consider the quality of the components underneath the bonnet, there is usually a reason if one machine is cheaper than another and the end result may be that one machine may last 5 years whereas the other may last 15 or more.
