In a commercial kitchen, hotel, or laundromat, water heater scale is a direct hit to your operating cost. A commercial heater or boiler runs hot all day; a ¼ inch of scale means 25–40% more fuel to make the same hot water — plus downtime, service calls, and early replacement of expensive equipment.

Where scale costs you

• Booster heaters & dish machines (restaurants)
• High-demand tankless banks (hotels, gyms, multi-unit)
• Laundry hot-water systems and light-commercial boilers

Right-sized salt-free protection

For light-commercial flow the inline DU line works; for higher demand we size a larger salt-free system to your load. Tell us your equipment and peak flow and we'll spec it and quote it fast.

Salt-free conditioners reduce and help prevent new water-heater scale; they are not softeners and do not remove existing hardness. Free U.S. shipping. See our hard water guide.
