What advantage does a hot water pressure washer have versus a cold water pressure washer? Well it ultimately comes down to time savings. A hot water pressure washer will out perform a cold water pressure washer about 3 to 1. The hot water will help cut through many different dirts and debris that the cold water will not. Hot water will melt and breakdown oils, grease and organics that cold water will just flush over. A couple good analogies that I use to explain these differences to the everyday person are the following:
Washing off dirty dishes, pots and pans
When you hand wash your dishes, pot and pans in your kitchen sink, you almost always use hot water to help breakdown and melt off the baked on food particles and oil/grease residue. By just using cold water, the food particles will just stay put and the oil and grease will just spread out over the dish. If cold water is your only option, you do more scrubbing to remove the debris or you incorporate some type of detergent to help in the breakdown of the unwanted particles and especially the oil and grease. Hot water makes much more sense to aid in the cleaning process cutting your time and effort.
Washing your hands
The same thing applies to hand washing. The cold water just doesn’t get the job done, especially if you have grease or oil residue on your hands. So, when cold water is the only option, it’s time to break out the costly heavy duty hand cleaner and a couple of squirts in the hands along with extra scrubbing and even the cold water still doesn’t really rinse everything off that well. The hot water really makes much more sense, again cutting and melting away the dirt and debris. Using the hot water will minimize and in most cases even elimate using the heavy duty hand soap.
Hot water pressure washing also has the ability to santize the item that you are cleaning. In some cleaning processes especially the food industry, santizing is a requirement and hot water pressure washing is the solution to get it done quickly and efficiently.
A guide that we have always used in comparing the power and cleaning ability of a hot water pressure washer to a cold water pressure washer is the following:
A hot water pressure washer operating at 2 gallons per minute (GPM) and 1200 pounds per square inch(PSI) will out perform a cold water pressure washer operating at 4GPM and 3500PSI. The hot water unit will do a better job at deep cleaning the surfaces and in roughly the same amount of time frame.
When looking to purchase or renting a power washer or pressure washer consider spending the extra money up front for a hot water unit versus a cold water unit, the type of cleaning you are doing and the amount of time you will spend cleaning. A hot water pressure washer can really be a better investment than a cold water pressure washer.
