Tankless Water Heater Installation & Replacement Snohomish County, WA





Enjoy Endless Hot Water with a New Tankless System
Thinking about a Tankless Water Heater Installation & Replacement in Snohomish County, WA? Elite Plumbing & Sewer can help you switch to an energy-efficient way to get all the hot water you need! Tankless water heaters, also known as on-demand water heaters, heat water only when you need it. This means you don’t have to keep a big tank of water hot all day long, which can save you money on your energy bills.
Imagine never running out of hot water in the middle of a shower again! That’s a big plus of a tankless system. Plus, they are much smaller than traditional tank water heaters, so they save space. Whether you want to install a gas tankless water heater or an electric tankless model, our expert plumbers make sure your new unit is set up right for top performance and safety, including all venting requirements for gas units.
Getting a tankless water heater installed correctly is key. At Elite Plumbing & Sewer, we understand how these advanced systems work. We’ll help you with proper sizing to pick the right unit for your home and family’s needs. We take care of connecting the water lines, gas or electrical hookups, and make sure everything is safe and up to code.

It’s pretty neat! When you turn on a hot water faucet, cold water flows into the tankless unit. A sensor detects the flow and turns on a powerful burner (for gas models) or an electric element (for electric models). This heats the water instantly as it passes through. When you turn the faucet off, the heater shuts down. So, you only use energy when you’re actually using hot water.
The biggest reasons are endless hot water (it never runs out!), energy savings (because it only heats water on demand), and they take up much less space than big tank heaters. They can also often last longer than traditional water heaters.
Installing a tankless water heater can take a bit longer than a regular tank model, usually several hours to a full day. This is because we might need to upgrade your gas line or electrical wiring, and install new venting pipes for gas units. If we are replacing an old tankless unit with a new one, it might be quicker.

brandon rossiter2025-04-30 We had a sewer pipe break in our crawl space and couldn't use our water and they where able to come out and fix it same day! Awesome work and saved us from having to wait several days for another company. Rachel2025-04-29 Very professional. He gave a realistic assessment about my water line situation. He got the job done quickly, at a good price. Jake Melby2025-04-05 Anthony was great! Installed a new tankless water heater for me and my wife has never been happier! bradley vongphrachanh2025-04-01 Elite plumbing and sewer is absolutely just the best. They answer their phone and communicate effectively which is a trait many contractors lack. Anthony showed up when he said he would. Quickly diagnosed why we weren’t getting water to our faucets after a main water line break and repair from folks working on the exterior of our house. You don’t realize how much you depend on running water until you don’t have it and there’s a toddler and infant in your house who need it. I would not hesitate to call Elite Plumbing & Sewer in the future. Thanks again, Anthony! Travis Clark2025-03-18 We were recommended Elite from a neighbor, and we had such an excellent experience. Anthony was knowledgeable, fair, clean, and best of all quick! He diagnosed the issue and had it working very fast. Price was very reasonable, and lower than my other quotes. 5 stars! Jason Scoppa2025-03-07 We were referred to Elite by an HVAC company after being told only plumbing companies can work on radiant heating systems. Anthony came out quickly and gave us a really honest and thorough assessment of our situation. I appreciate his good communication in terms of coordinating the visit and post-visit followup, and felt like he gave us some options and a solid interpretation of our situation. He suggested we wait and not do anything at the moment. I'll definitely reach out to them again and would recommend them if you're having plumbing problems or radiant heat problems! Matt Hart2025-03-01 Anthony knocked it out of the park. Job was done fast, clean, and with top notch quality. Anthony will be my first call for any needs going forward, big and small. Chris Bierrum2025-03-01 Anthony provided excellent, friendly service! Showed up on time and I felt was fairly priced. Will recommend to my friends and clients! Timothy Hutchins2025-02-26 Anthony at Elite was responsive, fair, and knowledgeable. It's obvious he's been trained by the best dennis hafner2025-02-26 Anthony does great work, communicates the scope of work and costs up front. He was able to get me scheduled right away, was on time and priced fair. If I need a plumber again, I’ll be calling Elite Plumbing again.
