"I need to share my experience with Clear All Rooter. I called them a few weeks ago to replace my 14 yr old water heater. I told them I wanted to use a water heater by Bradford and White. He quoted my $2800.00 for a 50 gallon water. I did not do my due diligence and just said go ahead and replace it. I was kind of stressed at the time. Only later did I realize that the heater cost $1020.00 and I ended up paying $1800.00 for installation which I consider a massive rip off. It is all my fault for not asking upfront about product cost and labor. Dont make the same mistake. I ended up making a home improvement loan to pay it off over the next two years. They did a great job of installation but I dont think it was worth $1800.00. I am a veteran who lives a modest lifestyle and I dont appreciate this type of treatment. Please beware when you use Clear All Rooter. This could happen to you."

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.
