Why Choose a Tankless Water Heater?
Homeowners upgrade to tankless for comfort, efficiency, and long-term savings. Benefits include:
- Endless hot water — No waiting for a tank to refill. Perfect for large families, back-to-back showers, and busy households.
- Lower energy bills — Heat water only when you turn on the tap, instead of storing gallons around the clock.
- Space savings — Compact wall-mounted units free up closet, garage, or utility-room space.
- Longer lifespan — Many tankless systems last 20+ years with proper maintenance — longer than most conventional tanks.
- Rebates & financing — Ask about available incentives and flexible HVAC financing options.

How Tankless Water Heaters Work
When you open a hot-water faucet, cold water flows into the tankless unit and is heated instantly by a gas burner or electric element. You get a continuous supply of hot water at the temperature you set — without a bulky storage tank.
We install both condensing and non-condensing models. Condensing units recycle extra heat for peak efficiency; non-condensing models are a strong value option with proper venting. Our technicians size the system for your household’s peak demand so showers, laundry, and dishwashers stay comfortable.
Tankless Brands We Install — Including Navien
As a local Navien specialist, we install and service Navien’s condensing tankless water heaters and related equipment. Navien units deliver reliable on-demand hot water with strong efficiency ratings and compact designs that fit Portland homes.

When to Replace Your System
Running out of hot water
If the tank empties mid-shower or you schedule laundry around recovery time, a tankless system can solve that permanently.
High energy bills
Conventional tanks keep water hot all day. Tankless systems only fire when you need hot water — often cutting water-heating costs.
Aging or leaking tank
Tanks typically last 10–15 years. Leaks, rust, or frequent repairs are a cue to upgrade before you have water damage.
Remodel or home addition
Adding bathrooms or an ADU? Tankless systems scale better for higher demand and free up valuable floor space.
