Does a hot water pressure washer cost more?
Yes, sometimes as much as two times more, due to the complexity of heating hot water while under pressure. Hot water pressure washers also require more preventive maintenance, such as the burner assembly, coil and redundant excess-pressure protection, all of which need annual tune-ups. Still, hot water pressure washers easily pay for themselves in labor cost savings by providing a faster, more effective pressure cleaning method. And because the water is pushed through the machine at such a powerful rate, less detergent is needed, which saves you even more money. How is water heated in a pressure washer? Water enters a pressure washer from a spigot or tank via a garden hose. It first passes through a high-pressure pump, which speeds the water on its way through a heating coil, consisting of up to 200 ft. of half-inch, schedule 80, steel pipe or tubing. The helical or circular winding configuration allows the water to get maximum exposure to the flame (fueled by diesel oil or natural gas
