"By far the best plumbing experience we’ve had so far in Denver. They came out the same day, didn’t charge a visit fee and provided a competitive no-obligation quote. On top of that, Chris was fantastic to work with, super friendly and took the time to explain each step of the work prior to performing it. I truly feel like I better understand the inner workings of my house after having him out. Fixed our ice maker box, installed our pre-purchased whole house filter, and threw in a complimentary toilet pump replacement. We’ve had several different companies out recently, most far more expensive, one slightly cheaper, but this was the first appointment where I wasn’t handed a tablet with financing options pre-generated. Wouldn’t hesitate to call them again."

FAQs for tankless water heater installation projects in Lone Tree, CO

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.
