Our Tankless Water Heater System Services for Seattle Homeowners
Are you looking for a new type of water heater? Call 206.792.7495 today for expert Seattle tankless water heater installation and repair and honest pricing. For many homeowners who try a tankless system, it’s the only way to go.
As the name suggests, tankless water heaters operate without a traditional hot water tank. There is no tank placed in your basement, because a heating element is connected directly to the plumbing system. When anyone in your household turns on a hot water faucet, you get hot water until you don’t need it anymore. Tankless systems are also called on demand water heaters because of this feature. The individual faucets receive the hot water when it’s needed, which makes for a much more enjoyable situation for people inside the house.
If you’re ready for instant hot water whenever you want it, Gene Johnson can help you set it up! Give us a call to speak with a knowledgeable member of our team about all the expert tankless water heater services we provide!

Frequently Asked Questions
Why Is My Tankless Water Heater Not Providing Consistent Hot Water?
Inconsistent hot water can happen for a few reasons. Mineral buildup in the heat exchanger, blocked filters, or low water flow are common culprits. In some cases, the system may be undersized for your household’s demand. A technician can:
- Clean or replace clogged filters
- Flush out scale buildup from the heat exchanger
- Check the gas pressure or electrical supply
- Inspect the venting and airflow system
When these parts are serviced, your system usually returns to normal operation. If the unit is too small for your family’s needs, we may recommend upgrading to a larger-capacity model.
What Should I Do If My Tankless Water Heater Displays an Error Code?
Error codes are the system’s way of telling you something is wrong. These codes can mean anything from ignition failure to venting problems. First, reset the system to see if it clears. If it returns, it’s best to call for service. A professional will:
- Interpret the error code correctly for your model
- Inspect electrical or gas connections
- Clean sensors and filters
- Replace faulty components if needed
Addressing error codes quickly helps you avoid bigger issues and costly breakdowns. Never ignore them, especially if your unit shuts off during operation.
How Can I Prevent Costly Repairs on My Tankless Water Heater?
Preventive maintenance is the key to keeping your tankless system working for years. At minimum, schedule annual professional service. During this visit, a technician will:
- Flush the unit to remove scale and mineral deposits
- Clean filters and sensors for proper operation
- Inspect gas or electrical connections
- Test water pressure and temperature settings
- Check for leaks or corrosion around connections
These steps reduce strain on the unit and prevent surprise breakdowns. With consistent maintenance, many tankless systems last 20 years or more.
How Long Does It Take to Replace a Traditional Water Heater With a Tankless System?
The timeline depends on your home’s setup, but most replacements are done in a single day. If gas lines, venting, or electrical upgrades are needed, it might take a little longer. Typically, the process involves disconnecting and removing your old tank, installing new hookups, mounting the tankless unit, and testing the system.
Our team works efficiently so your household experiences as little downtime as possible. Most families are enjoying unlimited hot water by the evening of installation day.
What Are the Biggest Benefits of Replacing My Old Tank With a Tankless Water Heater?
Replacing a traditional tank-style water heater with a tankless unit offers multiple long-term benefits:
- Endless hot water for back-to-back showers and multiple appliances
- Lower monthly energy bills because water is heated only on demand
- Space savings since tankless models are compact and wall-mounted
- Longer lifespan, with many units lasting 20 years or more
- Improved safety since there’s no large tank that could leak or burst
This switch is especially valuable for busy households in Seattle, where demand for hot water can be high.

I had an emergency water heater leak and called for help. Joe came out and got the old water heater removed and new one installed. He was very helpful and informative, I appreciate him getting this resolved so quickly. I’ll definitely use Gene Johnson again!
Janet englund
We had a new installation of a tankless hot water heater by Steven Fritz today and it was an amazingly painless and actually interesting procedure! He was very thorough and explained things fully and carefully and got the job done in a single day. Really impressive!
Catherine Hawley
We discovered very early in the morning that our hot water tank was leaking. I called Gene Johnson plumbing. The scheduler was efficient and thorough. About 15 minutes after I ended that call I received one from Pavel along with an email that he was on his way. He assessed the situation and got right to work. We now have a very functional new hot water heater, thanks to Pavel and Nathan. They were very knowledgeable and professional. Would happily recommend their services to friends and family.
Leah Grimshaw
Jaren came out today to fix our bathtub, which was significantly clogged. This was my first-ever experience calling a plumber, and it was terrific from start to finish. The person I spoke with to book was friendly and efficient. They were able to get me in the same day, and I appreciated receiving a text letting us know when the plumber would arrive, along with a picture of who would be coming. I also appreciated Jaren calling us to let us know he was going to be early and to check with us if that was okay. Jaren was kind, patient, and knowledgeable. He did a fantastic job all around. He had excellent communication with us and our HOA, and this was the best experience I’ve ever had with someone coming into my home for repairs. I am so happy my bathtub is back to normal, and I will recommend Gene Johnson to any of my friends and family. Jaren honestly made a nightmare situation manageable and even pleasant! Thank you again so much!

Rachel Doerflinger
Gene Johnson is incredible to work with. They assigned me a human customer care rep through text message named Samara who has been so amazingly helpful and caring during this whole frustrating leak process. Our technicians Greg and Rory who visited us a few different times were simply amazing, so understanding, and always helpful with an extremely positive attitude even when new issues arose. Tyler, the waterline team leader and expert, was so accommodating and understanding and made sure to set things up for me with Samara for an effortless scheduling experience on my end. Gene Johnson made me feel like family. Thank you so much. ❤️

Joe did a ton of investigative work and labor to address a pressure, pipe/water tank, and vent installation issue in our home. He is super knowledgeable and walked us through each step, with great tips for general maintenance along the way. Top notch professionalism and quality work!

Mark Ochoa was exceptional, showed up early and helped me in a bind. Would recommend without hesitation. Good to know who you can count on when needed
Peter Morawski
We’ve been with Gene Johnson for years, going back before the mergers. The service continues to be top notch. We recently signed up for the yearly membership and feel we are getting our money’s worth. Just got our first full plumbing inspection and are very glad to have the peace of mind to know what does or doesn’t need attention. The expertise of the staff is excellent, with a special shout out to today’s technician, Mark Ochoa, who was both knowledgeable and pleasant. Thank you kindly!
BJ Erkan from Bothell Integrated Health LLC
I am so used to people trying to upsell me that I was pleasantly surprised when Derek, our technician, gave exceptional service with zero upsell. So greatly appreciated. The seeds of future business have been planted, as when my next plumbing need arises, I will be calling Gene Johnson and asking for Derek.
Bruce Hobert
They provided prompt service to hook up new utility sink lines to my copper pipes. Andrew was professional and communicated well before, during and after the service. I would defuse them again!
Tim Lucas
Mark Ochoa did a fantastic job unclogging a stubborn blockage behind a washer. The plumbing made it hard to get to the problem, but he kept working on it until the issue was addressed. Nice to have that taken care of.

Irena Marcus
I had a great experience with Gene Johnson when I needed plumbing work done. My technician, Jeff Freeman, was professional, polite, and extremely knowledgeable — I really appreciated the quality of his work and how friendly and professional he was.
I also liked receiving a heads-up text and phone call with the estimated arrival time. The dispatch team was polite and professional as well, which made the whole process smooth and stress-free.
I will highly recommend this company!
Robin Campbell
We have a 14 yr old water heater I needed service. Taras (technician) was knowledgeable helpful and offered good advice on potential issues ahead.
Karen Epstein
Really appreciate the knowledge and expertise provided by Jaron. He was quick to diagnose the problem, efficient at unclogging the main line and a pleasure to work with. I have a good working knowledge of plumbing and I found Jaron to be honest and not looking to just drain my wallet.
Suzie Jaberg
Same day service, super friendly, super fast. Will definitely hire them again.
Eleanor Petrowitz
Rene was extremely professional, knowledgeable and perseverent. He unclogged my kitchen drain that was not easy. He kept at it, with many ideas and tries. Finally he got it. He did not give up. He was also very personable. I highly recommend him. He also found my leak that I had been trying to find for a month! It’s fixed, too.
