Heating module used to "convert" a cold-water pressure washer so it can provide hot water cleaning.
The 9400 heating module provides the flexibility to "convert" a cold-water pressure washer into a hot water unit. By attaching the heating module to a cold-water pressure washer, the pressurized water is now heated to produce all the benefits of hot water cleaning. Uses fuel oil or diesel to heat the water using a high-efficiency, vertical heating coil. Equipped with a flow switch to control the burner.
