Pressure washing professionals always take into consideration, when choosing the right pressure washer, the nozzle, power source, reliability and other features. One of the more important considerations however is the water that flows through the pressure washer. Power washers typically come in two types: cold water and hot water. Each is used for different reasons and offer different benefits. Below we explore both options and their applications.
COLD WATER PRESSURE WASHERS
Because the water does not need to be heated by your pressure washer, cold pressure washers do not have a burner. The temperature of the water won’t change as it goes through the system. These pressure washers are smaller, cheaper, safer, and more portable.
WHEN TO USE A COLD PRESSURE WASHER:
A cold pressure washer is perfect for rinsing your siding or sidewalk, as long as the surface has no major oil stains. When removing sand, dirt, or paint, you can use a cold pressure washer as well.
HOT WATER PRESSURE WASHERS
Hot pressure washers send water through a heating coil before blasting it onto the surface you want to clean. Recall from your childhood science classes that the molecules in hot water are moving much faster than those in cold. The strong energy in hot water reduces the water’s surface tension so it can penetrate grease and dirt more efficiently. By the time the water comes out of the nozzle, it could be as hot as 200 degrees Fahrenheit. Therefore, hot pressure washers clean better and faster than cold pressure washers. They can also cost twice as much.
WHEN TO USE A HOT PRESSURE WASHER:
If you need to clean an impenetrable surface, like concrete or brick, hot pressure washers will make the job quick and simple without causing damage. This is especially true if the surface has oil stains or gum stuck to it. A hot pressure washer can also help save money in the long run by finishing the job more effectively and quickly and by requiring less detergent.
If you’ve got some quick, light cleaning to do around the house, cold pressure washers are your best bet for safety, portability, and upfront cost. But i.f you’re looking to tackle a big, oily, industrial job, consider contacting your pressure washing service to get the work done fast, with the right equipment.
