6 Things to know before purchasing a pressure washer:

Cold Water vs. Hot Water Pressure Washers
Cold water pressure washers are fine for cleaning and flushing non-oily surfaces or for removing mold and mildew from patios, but when it comes to removing oils, greases, gum, road film, etc., a hot water pressure washer is needed as the heat from the water will change the chemistry of the targeted stain and get it moving. We like to say that there is chemistry (heat) and there is physics (psi), and the proper amount of each is needed for efficient cleaning. A good industrial hot water pressure washer will maintain a consistent temperature of 180 degrees. The hot water creates a molecular action that breaks the bond between grime and the surface to which it is attached.

Hot water pressure washers will more than cut your cleaning time in half. There are some jobs that a cold water pressure washer simply won’t clean. A hot water pressure washer will reduce your labor expense, as well as the amount of chemical needed to clean. About 95% of the trailer mounted pressure washers that we sell are industrial grade hot water machines.

Flow (gpm) and Pressure (psi)
When considering what “size” pressure washer that you are looking for, you need to consider both the GPM and PSI. More GPM is good for flushing or moving material. The more gpm, the more material you can push. Typical industrial machines will run at about 3000 to 3500 psi. All of our pressure washing equipment comes standard with a variable pressure wand to control pressure, as well as downstream chemical injection to control the application of detergent.

12V Burner System vs. On-Board Generator
A hot water pressure washer will have two power sources. The first will be for the motor and pump (usually a gas or diesel engine) to create the pressurized water, and the second will be the burner and coil system to heat the water. A 12V burner system draws its power from the unit’s battery. Even though the engine recharges the battery, more often than not the diodes do not generate enough amperage to keep up with burner demand. (This is even more true at altitude like we have here in Colorado.) As a result of low amperage, fan motors slow down which can clog the coil due to insufficient air flow. This also can drain the battery more than normal, so 12V systems are generally seen as less reliable units.

An 115V or 120V generator system can produce 10 times the voltage required to run an efficient burner system. Therefore a machine with a generator is 10 times more reliable. An additional benefit is most generators come with an outlet which can power some lights and small tools. While you will pay a little more for a machine with an on-board generator, the extra cost is well worth it due to the added reliability.

Horizontal Coil vs. Vertical Coil
A pressure washer with a horizontal coil will burn more fuel efficient than a machine with a vertical coil. Since heat naturally rises, a horizontal coil is designed to capture the heat more efficiently, resulting in a better temperature rise for your water, and you will use less fuel to get the water hotter. Our heating coils are wrapped in an anodized steel wrap and then surrounded by insulation to heat very efficiently. In addition, a horizontal coil has the burner protected behind the coil, not underneath it, where a vertical coil machine usually has burner issues with debris, soot, or rainwater getting into the burner. Having the burner behind the coil makes it very easy to adjust the air band, or perform any maintenance on the burner. A horizontal coil will also ride better on a trailer since the center of gravity is lower and more secured in the frame of the machine. We have seen many vertical coil machines in our service department with burner issues due to the placement of the coil. We are 100% convinced that a kerosene/diesel fired unit should have a horizontal coil.

Belt-Drive vs. Direct Drive Pump
All industrial trailer mounted pressure washers should have a belt-driven pump. A belt-driven pump with spin the pump about 60% less rpms which means the pump runs cooler and will last longer. In addition, the belts will absorb engine vibration. A belt-driven pump will also pull water from a water tank very effectively where a direct-drive machine may need an additional pump to feed water from the tank.

Warranty and Service
Beware of the bargain brands! Some brands claim to have quality machines because they come with a Honda engine. Honda does not make pressure washers, and an industrial pressure washer is certainly more than just an engine and pump. The way the components are engineered and the quality of the components directly relates to the reliability of the machine.

All of pressure washers that we sell come standard with a 7 year warranty on the industry leading Landa G3 pump, and also a 5 year warranty on the heating coil. We are a full service dealership, so we service and stock parts for everything that we sell. Since you can’t make any money when your machine is down, having a reliable dealer who stands behind the product is extremely important.
