Frequently Asked Questions


  • Is it worth switching to a tankless water heater in Georgia?

    Yes. While the initial investment is higher, Georgia homeowners benefit from lower monthly energy bills and a longer unit lifespan (up to 20 years). Tankless units are also ideal for North Georgia homes with limited basement or closet space.

  • How often do tankless water heaters need maintenance?

    Most manufacturers recommend a professional descaling (flushing) once every 12 to 24 months. In areas with harder water, such as Hall County or Dawsonville, annual maintenance is vital to prevent mineral buildup on the heating elements.

  • Can a tankless water heater run two showers at once?

    Absolutely. When sized correctly by a professional plumber, a high-efficiency tankless unit can provide enough Gallons Per Minute (GPM) to power multiple showers, a dishwasher, and a washing machine simultaneously without losing heat.

  • What are the most reliable tankless water heater brands?

    At Riverstone Plumbing, we recommend and service industry-leading brands including Rinnai, Navien, Rheem, and Bosch. These brands are known for their reliability, parts availability, and excellent warranties.
