5 REASONS PORTLAND HOMEOWNERS SWITCH TO TANKLESS
Tankless water heater installation in Portland, OR is one of the highest-ROI home upgrades available — especially for growing families, high-demand households, or anyone upgrading from an aging tank.
Tankless heaters heat water on demand — no storage tank means no running out. Shower as long as you want. No "wait for the tank to reheat" in a busy household.
Tank heaters maintain temperature 24/7 — burning gas or electricity even when you're not home. A condensing tankless unit like Navien runs at 96–97% efficiency, only firing when you need hot water.
PGE and Pacific Power customers may qualify for Oregon Energy Trust rebates on qualifying condensing tankless units. We're a registered contractor and handle the paperwork for you.
A tankless unit is the size of a carry-on suitcase and mounts to the wall. Replacing a 50-gallon tank frees up significant floor space in your utility room, closet, or garage.
A well-maintained tankless unit lasts 20+ years — twice the lifespan of a standard tank. With annual descaling and maintenance, many Navien and Rinnai units run reliably for 25 years.
A failing storage tank can release 40–75 gallons of water, causing significant property damage. Tankless units eliminate that risk entirely — no stored water, no catastrophic failure mode.
HOW WE COMPLETE YOUR TANKLESS WATER HEATER INSTALLATION
Proper tankless water heater installation in Portland, OR requires accurate sizing, gas line assessment, and venting expertise — not something to rush. Here's our process.
We calculate your household's peak hot water demand — number of fixtures, simultaneous use scenarios, incoming water temperature — and recommend the right GPM-rated unit. Undersizing is the #1 cause of tankless complaints. We don't let that happen.
Tankless units need higher BTU gas flow and dedicated direct-vent (PVC) exhaust. We check your current gas supply line and venting setup — if upgrades are required, they're quoted upfront in your flat-rate price. No "we found something" surprises.
We pull the required plumbing and gas permits, remove the old tank, install the new unit, run the PVC exhaust venting, and configure the unit to your household's temperature preferences. Most installs take 4–7 hours.
We run a full flow test — simultaneous fixtures, temperature stability, pressure — before we leave. If you qualify for Oregon Energy Trust rebates, we complete the application on your behalf. You get hot water and your rebate check.

WHAT PORTLAND TANKLESS CUSTOMERS SAY
Family of five — we were constantly running out of hot water. PDX Water Heater Pros installed a Navien NPE-240. Haven't run out of hot water once in 8 months. Gas bill dropped about $35/month. Worth every penny.
They handled everything — the gas line upgrade, new PVC venting, the Rinnai installation, and the Energy Trust rebate paperwork. Got $300 back from the rebate. Professional crew, clean work, done in 6 hours. Highly recommend.
I was quoted $4,500 by two other companies. PDX Water Heater Pros installed the same Navien model for $2,400 — with the gas line work included. They were honest about what was and wasn't needed. Zero upselling. Outstanding.
