Hydro Tek makes two line of pressure washers. The Ultimate Line is for the Cleaning Professional that needs all the power and quality extras he can get and the Pro Line is for the professional that needs quality, but has to work with in a budget. Cold water is generally used where grease and oil are not a factor, but with the right chemicals grease and oil can still be effectively dealt with. Consult a Hydro Tek dealer near you for the best advice in the application of cleaning chemicals. Cold water can only be as effective if the proper cleaning chemicals are also used.
Hot water can often make cleaning faster by loosening dirt, gum, grease and oil.
Most hot water units use diesel or kerosene to heat the pressurized water in a heavy duty heating coil. The heating coil and burner system makes the hot water unit much heavier, more complex and more difficult to maintain than a cold water unit. To run the burner system the unit requires electricity. Flow is important for rinsing horizontal surfaces or powering surface cleaning machines, such as our Hydro Twister . For a given amount of horsepower you can only get so much pressure and flow.
