The HWE Series electricity for both power and heat, making it ideal for indoor use. It’s a quiet machine with no fumes, making it the perfect choice for food service and in-plant cleaning. Water is heated in a stainless steel heating coil, immersed in a tank of water solution that creates instant hot water at the pull of the trigger. The heating elements do not come in contact with the pressurized water resulting in less maintenance and minimized scale build-up. The HWE features a Baldor motor, which drives a belt-drive Hotsy Triplex pump and an insulated variable pressure wand. As with all Hotsy Pressure Washers, the HWE Series is ETL safety certified.
