Hot Water vs. Cold Water

Unsure whether you need to use a cold water pressure washer or a hot water pressure washer? Well you're not alone! Check out this quick guide to choosing the right pressure washer for the job at hand.

Both hot and cold pressure washers are available with the same specifications and can both be used for the same indoor and outdoor cleaning jobs. So the real question is this - what are the additional benefits of a hot water system and are they the appropriate choice over a cold water system?

The first thing a hot water system introduces is probably the most obvious... heat! Hot water carries more energy than cold water and when used in cleaning it works more effectively at a molecular level to break down dirt.

Next on the list is detergent, also referred to as soap by most people. Detergents can be introduced into hot water systems to make the cleaning process more effective. This saves time and improves the end result, removing things like grease and oil that otherwise wouldn't be removed if using cold water.

So with this in mind, it's clear that a hot water system is the ideal choice for cleaning anything that engines, machinery or car parts where oil and grease are present. The combination of heat and detergent make hot water an effective solution.

In contrast, a cold water system is perfectly suitable for applications where there isn't a need to break down oils and grease making it the best option for cleaning away sand, mud etc.
