Do pressure washers use a lot of electricity?
Pressure washers normally connect to a garden hose and use electricity to power the pump within the unit electric power washers typically supply a maximum of 2,100 pounds of pressure per square inch (psi), in comparison to as much as 5,000 psi for a petrol-powered model.
Notwithstanding being a lot more powerful, they use less
water than your garden hose, making them extremely efficient. Power – A electric pressure washer's power is measured in watts.
Read the Label
The pump inside the unit that pressurises the water has an electrical rating, the rating can normally be found on a label, which is normally found close to where the plug or lead enters the casing of the pressure washer unit.
As you will see, the label may specify the draw in amps or power consumption, electric power washers generally draw around 12.5 amps when operating; this said, the better ones include tighter interior machinery that produces more pressure at the nozzle point.
At a voltage of 120 volts, the power consumption equals 12.5 amps times 120 volts, or 1,500 watts or (1.5 kilowatts) per hour. Therefore, to find out what an electric power washer uses per day simply multiply the number of kilowatt-hours uses per day by the price you pay for each kilowatt-hour of electricity. This price will vary depending on your location, you should be able to find it on your electricity bill. For example, at 13p per kilowatt-hour, a 1,500-watt pressure washer used for 8 hours per day will cost £1.56 per day, or £46.80 per month to operate.
