If you are entering the market for a best pressure washer because you heard they can make certain cleaning tasks easier, you may be bewildered by the wide array of choices available. Is a hot water pressure washer the right type for your intended application? Well, there are many benefits to using hot water, especially for cleaning applications. If you have a cleaning application that requires the removal of tough grease stains, hot water is the way to go. When combined with the proper cleanser or de-greasing agent, cleaning with hot water is a breeze. Industry experts all agree that hot water pressure washers clean better and faster when compared to their cold water counterparts. Cleaning faster means you waste less water and in certain applications this becomes a critical issue.
The water inside the pressure washer is heated by a boiler. The boilers come in different capacities and are made of different metals. In some parts of the country, propane is available everywhere and is the preferred fuel. If propane is not available easily in your area, there are other boiler types to suit your needs. You can buy a unit with a gas or diesel or electric heater. The choice will depend on fuel availability and also the price of the fuel. A good quality unit will have a stainless steel boiler and heater coils. If you are going to do large cleaning jobs you want a unit capable of continuous cleaning. If the unit is capable of continuous cleaning, that means it has the capacity to heat the water on the fly so you don’t have to wait for the water to heat up and stop cleaning while the boiler does its job.
Another metric that a hot water pressure washer is measured by is the flow rate and pressure. The pressure, commonly measured in PSI or pressure per square inch can be over 2000 PSI which can damage certain surfaces and peel paint off painted surfaces. It can also cause gouges in wood flooring and siding, so extreme caution is in order. Don’t get an extremely high pressure unit for delicate flooring. The flow rate determines how much water can be delivered at the rated pressure. Industrial pressure washer units can have flow rates of several gallons per minute.
