Commercial Tankless water heater

FLOW-AIDE® System Descaler quickly dissolves water scale, lime, rust, and other water formed deposits, restoring efficiency to most all appliances. FLOW-AIDE® System Descaler is a  non-toxic concentrate which is certified to NSF/ANSI 60 for use as a cleaner in potable water systems.

IMPROVE EQUIPMENT EFFICIENCY: Water scale deposits are a significant cause of heat transfer loss, along with the subsequent increase in energy costs. In fact, even a thin layer of scale (1/32") can cause a 30% increase in the cost to operate that piece of equipment. Keeping the heating passages free of mineral deposits significantly improves efficiency, conserves energy, extends the useful life of the equipment, and saves you time & money.

I used your product to clean out a customer tankless water heater, he has called me 3 times to thank me, that it worked so good. We use to use Acid and have to wear masks, but the smell was always there. We got Flow-Aide, from our jobber. No more smell. I think Flow-Aide does a better job.
