The 9400 Series Heating Modules give customers 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 (i.e. Hotsy 1700 Series) the pressurized water is now heated to produce all the benefits of hot water cleaning.
The four models use fuel oil, diesel, or natural gas to heat the water using Hotsy’s high-efficiency, vertical heating coil. All models are equipped with a flow switch to control the burner. All models are ETL-Certified to the rigid UL-1776 safety standards and CSA-Certified.
