What the job includes

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.

How the service works

How a tankless installation is planned

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.

STEP 01

Build a hot-water demand profile

The estimate considers fixtures that may run together, the temperature rise needed, and whether the household expects simultaneous showers, laundry, or large-tub filling.

STEP 02

Check the supporting infrastructure

Gas supply, electrical service, vent route, combustion air, condensate handling, water piping, and mounting space are reviewed before the installation scope is finalized.

STEP 03

Install, commission, and explain maintenance

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.

Diagnosis before recommendation

When tankless fits, and when it may not

Tankless can be an excellent choice, but the building and usage pattern have to support it.

Peak flow versus average use

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.

Upgrade scope

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.

Maintenance and service access

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.

Home base + regional coverage

Vancouver is home. Our service area reaches farther.

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.

Vancouver & Clark County

Size for Southwest Washington conditions

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.

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.

Tankless questions

Is a tankless water heater worth it for a Vancouver home?
Tankless can make sense when the household values compact equipment and long hot-water runs, and the building can support the required flow, fuel or electrical load, venting, condensate, and maintenance access. The right answer depends on the existing system and actual peak demand.
How do you size a tankless water heater?
Sizing uses the flow rates of fixtures that may run together and the temperature rise needed between incoming water and the desired outlet temperature. A unit sized only by bedroom count may disappoint when showers, faucets, or appliances overlap.
Will my gas line support a tankless water heater?
Tankless gas units can have a different input demand than a storage tank. The existing meter or regulator, total connected appliance load, pipe size, route length, and pressure all need to be considered before deciding whether the current gas piping is adequate.
What other upgrades can a tankless installation require?
Depending on the selected unit and existing home, the scope may include gas piping, venting, combustion-air provisions, condensate drainage, electrical service, water connections, isolation valves, and wall mounting. These items should be identified before comparing a tankless quote with a simple tank swap.
Does tankless mean hot water reaches the faucet instantly?
No. A tankless unit heats water on demand, but water already sitting in the branch pipe still has to travel out before newly heated water reaches the fixture. Pipe length and layout affect wait time unless a compatible recirculation strategy is included.
What maintenance does a tankless water heater need?
Maintenance needs depend on the model, water quality, usage, and manufacturer instructions. Scale control, inlet-screen cleaning, combustion or electrical checks, and keeping service access clear can all matter, especially where mineral buildup affects the heat exchanger.
