Honest sizing
Flow rate matched to your fixtures and habits, not a brochure.
Endless hot water and a mechanical closet you get back. We size it right, upgrade the gas and venting properly, and tell you honestly when tankless is not the right call.

A tankless unit heats water on demand instead of keeping 50 gallons hot around the clock, which is why the running costs drop and the hot water never runs out. The part most installers skim past: a gas tankless unit usually draws far more gas at full fire than the tank it replaces, so the existing gas line and venting often need to be upsized to do the job safely. We check that before quoting, not after opening the wall, and we handle the permit and inspection that Washington requires.
We install and service the major brands, and we service what we install. Our techs handle tankless maintenance calls across Clark County every week, including periodic descaling that keeps the heat exchanger efficient. If your household or your gas service makes a high-recovery tank the smarter buy, we will say so plainly. Free estimates either way, and $125 off a water heater installation when you mention the offer on this page.

Descaling and repairs from the team that installed it.
Tankless performance depends on peak flow, incoming water temperature, fuel or electrical capacity, venting, and maintenance access. Product selection comes after those conditions are measured.
The estimate considers fixtures that may run together, the temperature rise needed, and whether the household expects simultaneous showers, laundry, or large-tub filling.
Gas supply, electrical service, vent route, combustion air, condensate handling, water piping, and mounting space are reviewed before the installation scope is finalized.
The unit is installed to its listed requirements, started under demand, and checked for stable temperature and flow. Shutoffs and future flushing access are reviewed with the homeowner.
Tankless can be an excellent choice, but the building and usage pattern have to support it.
A household may use modest hot water overall but still need high output when multiple fixtures run at once. Sizing is based on that peak condition.
The heater may need a larger gas line, a new vent path, condensate disposal, or electrical work. Those supporting changes can materially affect the project.
Isolation valves and usable clearance make future flushing and repairs practical. A tight installation that cannot be serviced is not a good long-term result.
True Plumbing is based in Vancouver, where our team, reputation, and service operation are centered. We also serve nearby communities across southwest Washington and the east Portland metro.
Incoming water is colder in winter than in summer, which increases the temperature rise a tankless unit must deliver. A Vancouver-area estimate should use realistic cold-weather demand rather than a warm-climate flow number from a product brochure.
Dedicated coverage for downtown, the waterfront, east Vancouver, and surrounding neighborhoods, backed by a local shop off NE 60th Way.

Jason R. was awesome! He came out to service our tankless water heater and was super friendly, knowledgeable, and professional. He explained everything clearly and got the job done quickly.
With a 20 year old, 80 gallon water heater on its last leg and leaking, I had many questions but little time. Jesse S. walked me through it on two separate occasions before the install.
Jason squeezed me in near the end of the day on a Friday and stayed late to get my water heater fixed. Prompt, communicated well, and saved my weekend.
