Citrus,not salt.Proven on tankless.

In an independent third-party study conducted with the Battelle Memorial Institute, NuvoH2O prevented over 98% of scale formation in electric tankless water heaters. Treated heaters also reached a steady temperature over 25% faster. That means less waiting for hot water, and less energy spent getting there.

Why Protect Your Tankless Heater

  • Faster hot water

    Less scale on the heating elements means hot water arrives sooner.

  • Lower energy use

    A clean heater doesn't burn extra energy pushing through buildup.

  • Longer life

    Keeping scale off internal parts helps your heater keep running like it should.

Frequently Asked Questions

Where does it install?

On the cold water line feeding your tankless heater. The 3/4" ports fit standard residential lines.

My heater already has scale. Will this help?

CitraCharge™ works on existing buildup over time. Heavily scaled heaters may not fully recover, and it can't reverse corrosion that's already happened.

How often do I replace the cartridge?

Every 5 months. It's a quick, simple cartridge swap.

Does it change my water?

No salt or sodium is added, and the calcium and magnesium stay in the water. It just can't stick to your heater.
