Water is heated in a stainless steel heating coil, immersed in a tank of water solution, allowing for instant hot water once you pull the trigger. The heating elements do not come in contact with the pressurized water, which results in less maintenance and minimizes scale build up. Features a Baldor motor, which drives a belt-drive Hotsy Triplex pump, with 7-year warranty, and an insulted variable pressure wand. ETL certified. Flow switch standard. Equipped with 50' hose.
