Hot Water vs Cold Water Pressure Washing
Pressure washers can be categorized in several different ways: electric, gas-powered, residential or commercial. There is also another classification, and that’s cold or hot water pressure washers. Apart from the temperature of water they use, they differ in several other areas as well. Of course they both have their pros and cons, and knowing more about each will help you make a better decision.
Cold Water Pressure Washing
Cold Water Pressure Washers are much cheaper and simpler in their construction when compared to their hot water counterparts (especially electric models).
Also, cold water pressure washers are a lot more practical due to their smaller dimensions which make them easier to move around. As far as maintenance goes even gas-powered pressure washers are a lot easier to maintain than the equivalent hot water designs.
Cold water pressure washers rely on the mechanical force of a pressurized water jet to dislodge dirt from the surface that needs to be cleaned. This force is usually enough to break down most impurities, but they are less efficient when it comes to tackling oily or greasy stains that can be found on hard surfaces such as garage floors, pavements and driveways. The use of detergents helps out a bit on some of the less tough stains, but oil and grease are often too much to handle for most cold pressure washers.
Cold water power washers rely on high-pressure water jets to remove dirt, and the higher the PSI and GPM number, the more powerful the pressure washer is.
Hot Water Pressure Washing
Water molecules break free from their bonds when heated up to over 200F, that’s how you get steam. It is basically the same with grease and oil molecules. As temperatures rise, their energy levels increase and they can break free from the surfaces they are embedded in. Of course, hot water power washers also use the mechanical force of pressurized water to expel oil and grease particles from the surface. Finally, using soap breaks down the bonds created by grease and oil at a molecular level.
Hot water pressure washers have the ability to produce steam which comes in really handy if you want to get surfaces spotless to the point where they’re germ free. However, a hot water and high pressure combo is more effective than just steam. You may also notice that hot water pressure washers have a lower PSI than gas-powered pressure washers.They are big, bulky and thanks to their complex design, more complicated to maintain. They are also more expensive.
