"We can’t say enough great things about David from The Hot Water Heater Company – Carolinas (HotCo). Our old direct vented gas water heater met a disastrous end, and David came to the rescue with professionalism, expertise, and incredible speed. He removed the defunct unit and installed a finely tuned Navien tankless water heater—all within just a few hours. The service wasn’t just timely—it was above and beyond. David is the ultimate professional, and thanks to him, we’re back up and running with endless hot water and peace of mind. We are truly grateful! "

"LVP looks great and tile in the kitchen look great but the trim and baseboards were not finished and I had to have another contractor come in and install them. The stairwell was sanded and stained and I was told they could match the stain for the stairs to the LVP and that wasn’t true either. The stairs came out pink. Now I’m having another contractor come in and fix. I would not recommend to a friend."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
