"We wanted to switch out our 20 year old water heater with a tankless option — to both save space and energy. Trinity plumbing was a great company. Sent an estimator out same day and really knew what they were talking about. I feel confident in a lot of my home renovation knowledge from the fact that both my parents build multiple of our homes but plumbing I am lost on. They were incredibly helpful and got the job done in no time! I was impressed all around. I might actually show our new water heater off the any guest that come visit 😂 job well done"

FAQs for tankless water heater installation projects in Portland, OR

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.
