Oak Ridge, Anderson County
Tankless Water Heaters in Oak Ridge, TN
Endless hot water, and no tank sitting in the garage waiting to fail.
We cover tankless water heaters throughout Oak Ridge and the rest of Anderson County. We work the Knoxville side constantly, so Oak Ridge is a regular stop rather than an out-of-area trip.
Most homes in Oak Ridge are on city water, so supply problems here are usually inside the house — a failing line, a bad valve, or a water heater at the end of its life — rather than anything to do with a pump.
A great deal of the housing stock dates to the 1940s-50s, which means original galvanised supply and cast iron drains are still in service.
What the job involves
- Sizing the unit to the real fixture count, not the brochure
- Gas line sizing -- a tankless unit usually needs more gas than the tank it replaces
- Venting, condensate and isolation valves on both sides so it can actually be serviced
- Descaling and maintenance afterwards
One firm price
Your estimate in Oak Ridge is a single firm number for the work described. Not a range, not a “starting at”, and not a good-better-best menu. We look at the job, tell you what it costs, and that is what it costs.
And we answer the phone
Nearly every shop around here closes at five and sends you to voicemail until Monday. Call us at any hour and your call gets answered — we take your details and get straight back to you. For anything urgent in Oak Ridge, that is the difference that matters.
Tankless Water Heaters in Oak Ridge — common questions
Do I need a bigger gas line for a tankless heater?
Usually yes. A tankless unit burns far more gas at once than the tank it replaces, and running it on an undersized line is the most common mistake we see on units fitted by someone else. We size the line for the whole load, not just the heater.
Do tankless heaters need servicing?
Yes — they need descaling, and on hard or well water they need it more often. We fit isolation valves on both sides when we install one specifically so it can be serviced without draining the house.

★★★★★3 months agoReasonable price
Had a main line break water more than tripped and since I used them before for something else I used them again. Main line all lines under our old house and new lines inside. Fair price given up front and a good crew, polite and triple checked their work with me. If anyone needs a plumber then give them a call and have them out to check. Ronnie is very professional.

★★★★★4 months agoVery responsive and clear communicators. Ronnie worked with me on a septic to sewer project. His resources and connections all panned out making it roll more smoothly. High Level is now my go-to company for my properties.
