When it comes to pressure washers, there are two main types: hot water and cold water. Each type has its own unique benefits and drawbacks. So which one is right for you? Here, we will discuss the pros and cons of each type of pressure washer so that you can make an informed decision.
Cold Water Pressure Washers
Cold water pressure washers use, you guessed it, cold water. They are typically used for jobs that do not require hot water, such as cleaning hard surfaces or removing dirt and grime. Cold water pressure washers are also better for surfaces that can warp with heat, such as wood decks.
These are the most common pressure washers on the market, and are what the vast majority of homeowners are likely to use. Since most people tend to use this type, you’ll see cold water units make up a majority of our best pressure washer list each year.
How do cold water pressure washers work?
Cold water pressure washers work by using pressurized water to remove dirt, grime, and other debris from surfaces. The pressure of the water does all the work, so there is no need for hot water.
Pressure is measured in pounds per square inch (PSI). The higher the PSI, the more pressure the washer will have. Cold water systems typically have PSIs between 1500 and 3000.

Hot Water Pressure Washers (Power Washers)
Hot water pressure washers use hot water to remove dirt, grime, and other debris from surfaces. The hot water is more effective at breaking down tough stains and removing stubborn dirt. Hot water pressure washers are also great for sanitizing surfaces.
