How to Choose the Best Hot Water Pressure Washer

When choosing a hot pressure washer, there are several features that you should consider.

Power Source: Gas vs. Electric

One of the first things to consider is how the washer is powered. Does it use gas, or is it powered by a battery (electric)?

The right option for you will depend on your needs and the purpose of the washer. Electric power washers are environmentally friendly, quiet, light and cordless, but they’re not as powerful as gas-powered models and may run out of power quickly.

Gas-powered models may require additional maintenance and require fuel, but they tend to be more powerful and have longer run times.

For small jobs that don’t require a hefty amount of power, an electric model may be a good choice. For bigger jobs that require more power, a gas-powered pressure washer may be your only option.

Water Temperature

Another important consideration is the water temperature. The hotter the water, the easier it will be to clean your equipment.

Hot water makes it easier to loosen dirt, oil, grease, and manure, which saves you time and water.

Look for a temperature range that meets your needs.

Steam Capabilities

If you need a hot water pressure washer for tough jobs, choosing a model with steam capabilities can be beneficial.

Steam options boost the washer’s cleaning power while improving efficiency.

Fuel Capacity

If you choose a gas-powered pressure washer, you will need to consider fuel capacity, or how much fuel the tank can hold.

The larger the capacity, the longer the run time. However, a greater capacity comes at the cost of a heavier machine.

Fuel tank capacities can vary. Some hold 4 gallons, and others can hold as much as 10 gallons of fuel.

It’s important to consider what you’ll be using your power washer for. If you have quite a bit of farm equipment that needs to be cleaned daily, you may want to go with a model that has a bigger fuel tank.

Cleaning Power

The most important thing to consider when choosing a hot water pressure washer is performance. Cleaning power is determined by PSI and GPM will be the main factors affecting performance.

  1. PSI refers to the amount of cleaning pressure the washer can produce.
  2. GPM refers to the amount of water (gallons per minute) the unit uses.

It’s easy to assume that PSI is more important than GPM, but that’s not necessarily the case. Both play an important role in cleaning power. A pressure washer with a high PSI and low GPM may have the same cleaning power as a unit with lower PSI and higher GPM.

Frequently Asked Questions

How Do Hot Water Pressure Washers Work?

Hot water pressure washers work by first heating the water and then using a pump to force the water through a constrictor nozzle. The high pressure helps lift and remove dirt, grime and grease.

Most pressure washers heat water by using propane, diesel, natural gas or kerosene. Most heaters can provide four or more continuous hours of washing because the water is heated as it enters the heat chamber.

Pressure washers use a pump to circulate water continuously through the unit. When the trigger on the wand is pulled, the water is forced through the constriction nozzle. It’s not the pump that creates the pressure, but the constriction from the nozzle.

Hot pressure washers come with different nozzles, and these nozzles will adjust the pressure level. The nozzles are sized by fractions of an inch in diameter.

Is Hot Water Pressure Washing Better Than Using Cold Water?

Overall, hot water pressure washing offers greater cleaning power compared to cold water. That’s because hot water is more effective at lifting dirt, grime and grease. Cleaning is quicker and more efficient for this reason.

Should I Use Soap In My Pressure Washer?

Yes. In fact, using soap and detergent can help improve the washer’s cleaning power and help you get the job done faster.

Final Verdict

The right pressure washer for your farm will depend on your needs and purpose. Larger commercial operations will need a larger water tank and greater power to get jobs done more efficiently. Smaller operations and cleaning jobs may only need a small electric unit, like the XtremepowerUS we reviewed above.

Take the time to consider your needs and the points we’ve outlined above to find a unit that’s right for your farm.
