Cold Water Pressure Washers are typically purchased by most homeowners. But commercial companies that do not need to rely on hot water as part of their cleaning requirements also use them. Asbestos removal, painters, masonry companies, HVAC companies cleaning filters, when used for mud removal only, and companies located in climates with hot weather year around. Many manufacturers offer a heater only model. This allows for the owner of cold water pressure washer to add a portable hot water heater. Many customers like the convenience of having the pressure washer separate from the portable heater allowing them to only take the pressure washer portion to certain jobs, but having the ability of generating hot water if needed for other tasks. This can also be an economical way to grow in to more types of cleaning jobs as your needs change.
Hot Water models are used by companies that encounter cleaning challenges involving oil, grease, hydraulic fluid, and food grease to name a few. Hot Water Pressure Washers are almost necessary for companies cleaning in cold climate regions. It is nearly impossible to get soils to release from steel or metal surfaces without first warming the surface up. Imagine the success of getting road film on a vehicle off that has been parked outside in the winter time and you are spraying it off with cold 40 to 50-degree water. Hot water also activates chemicals being used increasing their performance when combined with agitation created by spray. If in doubt I have one simple test for you to conduct at home which will make you a believer. Load your dishwasher with dirty dishes and wash them with cold water only. You still have agitation (Spray) and soap present with the only component missing being hot water. Now repeat the same process with the addition of hot water. Whether washing dirty dishes, dirty clothes, or cleaning with a pressure washer, the addition of hot water is significant.
