I pride myself on my professionalism, as well as my ability to complete every job to the homeowner's total satisfaction. I never leave a job unfinished, or a homeowner not 100% satisfied with my level of service - Call today!

"Lanny and his crew replaced all the existing plumbing (rusting galvanized pipe throughout) and replaced the leaking hot water heater. He was very easy to work with, we had some extenuating circumstances, that they graciously accommodated. The price was excellent and the workmanship was even better. Highly recommend!! Thanks, again, Lanny! "

FAQs for tankless water heater installation projects in Boulder, 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.
