Tankless Water Heater Repair & Installation in Wilsonville, Oregon
Endless hot water, lower energy bills, and a 20+ year service life. Tankless water heaters are the most significant upgrade available for most Wilsonville homes' plumbing systems. True Flow Plumbing PDX installs whole-home tankless systems throughout Wilsonville.
Tankless Water Heater Installation in Wilsonville
Wilsonville's newer master-planned communities — Villebois, Coffee Lake Landing, and Frog Pond — have larger homes with multiple bathrooms and high hot water demand. Tank water heaters in these 10–20-year-old homes are reaching their first replacement cycle, and many homeowners are choosing to upgrade to tankless at the same time rather than just replacing like-for-like. We install whole-home tankless systems in Wilsonville regularly.
⚡ Whole-Home Tankless Installation
We size the unit to your household's peak demand — number of bathrooms, appliances, and simultaneous hot water uses — and install the right unit the first time.
🔥 Gas Line Upgrades
Tankless units need more gas than tank heaters. We upgrade your supply line if needed as part of the installation — this is included in your quote up front.
🌡️ Temperature Setting & Efficiency
We set up the unit at the right temperature for your household and explain the efficiency settings. Most tankless units have a modulating burner that adjusts gas use to match demand.
🔧 Old Tank Removal
We disconnect and haul away your old water heater as part of the installation. Proper disposal is included.
📋 Permits & Inspection
Tankless installation requires a permit in {city}. We pull it, do the work, and schedule the inspection — you don't have to manage any of that.
🔩 Recirculation Options
For larger {city} homes with long pipe runs, we can add a recirculation pump to deliver instant hot water to distant fixtures without running cold water down the drain first.

Tankless Repair, Service & Descaling in Wilsonville
Wilsonville draws treated Willamette River water and is built almost entirely of newer housing, which means tankless units here were generally installed properly and are generally in good condition. The service we do is preventive more often than emergency, and the most common finding is simply that nobody ever scheduled the annual descale.
Nobody scheduled the service
The recurring story in Wilsonville. The install was correct, the unit has performed for a decade, and it has never been descaled because no one mentioned it at handover. The fix is straightforward if it is caught before output drops noticeably.
Descaling
Willamette supply is moderate on hardness. Scale still forms, just steadily rather than fast, and the manufacturer warranty assumes annual attention regardless of source water.
Demand across a larger floor plan
Newer Wilsonville homes have the bathroom count to out-draw a modestly sized unit when everything runs at once. That is a sizing ceiling, not a malfunction.
Condensate drain issues
High-efficiency condensing units produce real water and need somewhere to put it. A blocked or badly routed condensate line causes shutdowns that look mysterious until you find the drain.
Error codes
The unit tells you what it thinks is wrong. Note the code before resetting.

Frequently Asked Questions
How does a tankless water heater work in a Wilsonville home?
A tankless water heater heats water on demand as it flows through the unit — there's no storage tank that can run out. When you turn on a hot tap, cold water enters the heater, passes over a heat exchanger powered by gas burners, and exits at your set temperature within seconds. The water heats continuously as long as the tap is open, meaning hot water doesn't run out regardless of how long your shower is.
Will a tankless water heater work with my existing gas line in Wilsonville?
It depends on your current gas line size and pressure. Whole-home tankless units require significantly more BTUs than a standard tank heater — typically 150,000–200,000 BTU versus 36,000–50,000 BTU for a tank. Most 1970s–2010s Wilsonville homes need a gas supply line upgrade to support this load. We assess your current gas supply capacity as part of every tankless quote and include line upgrades when needed.
What's the payback period on a tankless water heater in Wilsonville?
A tankless unit costs more upfront than a tank replacement but operates at 20–30% greater efficiency due to the elimination of standby heat loss. At average Wilsonville household gas rates, most tankless installations pay back the difference in 5–8 years through energy savings — and the unit itself lasts 20+ years compared to 8–12 for a tank. For households running a lot of hot water, the payback period is shorter.
