Hot Water Pressure Washer: An In-Depth Guide
Hot water pressure washers are highly effective cleaning tools, particularly for heavy-duty applications that require grease, oil, and grime removal. They are widely used in industries, workshops, and homes for tasks that demand both pressure and heat. However, like any machine, they can develop issues over time, necessitating maintenance and repair. For residents seeking Hot Water Pressure Washer Repair in Nairobi, this article provides a comprehensive guide to understanding these machines, common problems, repair solutions, and the associated costs.
How a Hot Water Pressure Washer Works
A hot water pressure washer combines high-pressure water with heat to enhance cleaning power. Here’s the basic process:
- Water Supply: Water enters the machine through a hose connected to a tap or tank.
- Pump: The pump pressurizes the water, typically at 2,000–4,000 PSI.
- Heating Element or Coil: Water flows through a heating coil powered by gas, diesel, or electricity, raising its temperature to about 90–150°C.
- Spray Nozzle: The heated, pressurized water exits through the nozzle, delivering a powerful jet for cleaning tough stains.
- Detergent Injector (Optional): Many models include a detergent injection system for enhanced cleaning.
