Tankless Water Heater Installation in Oregon City | Hot Water On Demand, No Tank to Store

We provide Tankless Water Heater Installation throughout Oregon’s Clackamas, Multnomah, Washington, Marion, and Yamhill Counties.

A tankless water heater heats water only when you turn on the tap, so you never run out mid-shower and you are not paying to keep 50 gallons hot around the clock. Our plumbers size the unit to your home’s flow rate, handle the gas or electrical work, and set the venting so the system runs safely and efficiently. We are a family-owned shop in Oregon City with 5.0-star Google reviews. Call (503) 919-7243 or request an estimate online.

Tankless Water Heater Installation for Oregon City Homes

Tankless water heater installation in Oregon City means mounting a wall-hung unit that heats water on demand instead of storing it in a tank. The install differs from a standard tank swap because tankless units need specific gas line sizing (or a dedicated circuit for electric models), proper venting, and flow rate calculations to match your household demand. We install tankless systems across Clackamas, Multnomah, and Washington counties as part of our water heater services from our Oregon City plumbing team.

When it is time for tankless water heater installation

If your family regularly runs out of hot water because the tank cannot keep up with back-to-back showers, a dishwasher, and a washing machine, a tankless unit solves that by heating water continuously. If your current tank water heater is aging out and you want a longer-lasting replacement, tankless units typically run 15 to 20 years versus 8 to 12 for tanks. If you are reclaiming garage, utility closet, or basement space, a wall-mounted tankless unit frees up the floor area a 50-gallon tank occupies.

Homeowners upgrading older Oregon City homes in Park Place and the McLoughlin area often choose tankless when replacing a failing tank because the long-term energy savings and space recovery make the higher upfront cost worth it.

Our tankless water heater installation process

We calculate your peak hot water demand in gallons per minute (GPM) based on how many fixtures and appliances could run at the same time. We check the existing gas line size to confirm it can deliver enough BTUs. If the line is undersized (common in homes that had a lower-BTU tank heater) we size and run a new gas line section. For electric tankless, we verify the panel has capacity for the dedicated circuit.

We mount the unit, connect water supply and hot water output lines, run venting through an exterior wall or roof, and pipe condensate drainage for condensing models. We fire the unit, test flow rate at multiple fixtures running at once, and set the output temperature.

Tankless water heater installation cost in Oregon City

Tankless installation costs more upfront than a tank replacement because the unit is more expensive and the install often includes gas line work, new venting, and electrical modifications. A gas tankless install where the gas line and venting path are already adequate is on the lower end. Jobs requiring new gas line, venting through masonry, or panel upgrades add scope. We assess your home and give you a complete price before ordering. Call (503) 919-7243 to schedule the assessment.

Nate was so nice, him and his workers did such a good job on my bathtub in my guest house.
google
We recently had Nate, the owner of Principled Plumbing, come out to our home to fix a minor sink plumbing issue that a previous contractor had completely missed—and we couldn’t be more impressed.

Nate was honest, straightforward, and clearly takes pride in his work and customer service. He quickly identified and fixed the problem, explaining everything in a way that was easy to understand.

What really stood out was that he also provided us with a quote to replace the plumbing in our manufactured home, and there was absolutely no pressure to move forward. It’s rare to find someone who is both knowledgeable and genuinely respectful of your time and decisions.

If you’re looking for a plumber who is trustworthy, professional, and truly customer-focused, we highly recommend Nate at Principled Plumbing!

Nate, Justus and his team are the best. Great customer service, really knowledgeable, and performs the job right. They go above and beyond to meet the customer’s expectations. They never asked or bugged me for reviews or rate like other companies that I dealt with.

Nate, the owner was great. He was responsive and easy to get ahold of. Communication was great. As soon as I scheduled my appointment, I received email confirmation. Nate also sent a text reminder the day before the appointment which I appreciate. Justus from Principled Plumbing installed 3 new shower systems in each of my bathrooms. He did a wonderful job. He was punctual and was very pleasant to work with. The job took all day and Justus maintained a positive attitude throughout. He was very professional, knowledgeable and so helpful. I love my new shower system. What an upgrade to my shower. I definitely recommend Principled Plumbing for all your plumbing needs.

I went to George Morlan Plumbing to see about buying a recirculation pump. I found that for me to install it I would have to purchase tools that would be in excess of how much a plumber would charge me to install it. I was encouraged to call Principled Plumbing for an estimate. I called and got a text from Nate, the owner, who said they could come out the next day to look at the job. One of his employees, Justus, arrived the next day as scheduled to look at the job and gave me a very reasonable estimate. He arrived the next day on time with George, another employee, to install everything. Both were extremely courteous and professional. I couldn't be happier with the quality of their work and the quick response to my job.
google
Nate and justus are great! I have worked with them on multiple projects and have always got professional results within timing, price and quality. I highly recommend principled plumbing!
google
Nate was really kind on the phone and Justus was efficient in completing the work. Justus was very thoughtful and helped educate me on each part of the process. Justus worked quickly and cleared our drain in under an hour despite the challenges of an older plumbing system.

Plumbing issues are never pleasant, Nate and Justus made it a bit easier being timely, kind, and honest.

Flat rates for most projects. Declogging is hourly though!
