Tired of Running Out of Hot Water Mid-Shower?

A tankless water heater fixes that problem for good.

Traditional tank water heaters store 40 to 50 gallons of hot water and reheat it on a cycle, whether you need it or not. When the tank runs out, you're waiting. A tankless water heater (also called an on-demand water heater) heats water only when you turn on the tap, so you never run out.

For Portland homeowners, that means hot showers on demand, lower monthly energy bills, and a unit that typically lasts 20 years or more versus 10 to 12 for a standard tank. If your current water heater is aging, running out of hot water, or just not keeping up with your household, going tankless is one of the smartest upgrades you can make.

Frequently Asked Questions

Can a tankless water heater run out of hot water?

A properly sized tankless unit will not run out of hot water. The key word is properly sized. Nolan assesses your household's peak demand before recommending a unit, so your tankless heater can keep up with simultaneous showers, laundry, and dishes without losing heat.

Do tankless water heaters require maintenance?

Yes. Annual flushing to remove mineral buildup (especially important with Portland's water) keeps your unit running efficiently and protects your warranty. PDX Plumber offers maintenance service and can set up a simple schedule to keep your system in top shape.

How long does it take to install a tankless water heater?

Most tankless water heater installs take between 3 and 6 hours. If gas line upgrades or new venting are required, same-day completion is still common with PDX Plumber. We come prepared with a fully stocked van to avoid unnecessary delays.

Is a tankless water heater worth it in Portland?

For most Portland homeowners, yes. Tankless units use 20 to 30 percent less energy than traditional tanks, last nearly twice as long, and deliver unlimited hot water on demand. If you have a larger household or high hot water usage, the long-term savings are significant.

How much does tankless water heater installation cost in Portland, OR?

Tankless water heater installation in Portland typically ranges from $1,000 to $3,500 or more depending on the unit, fuel type, and any gas line or electrical work required. PDX Plumber provides upfront quotes before any work begins, so you know exactly what you're paying.
