About Nooga Water Heaters — Chattanooga's Water Heater Specialists
We do one thing: install, replace, and service water heaters for Chattanooga homeowners and our neighbors across NW Georgia. That singular focus is what makes us different — and it's what makes us better at this than anyone else in the metro.
Why a Water Heater Specialist?
Most plumbing companies treat water heater work as one item on a long menu — between drain cleaning, pipe repair, fixture installation, and bathroom remodels. Their technicians rotate between jobs all day, switching context constantly.
We built this company around a different idea: every technician on our team works on water heaters all day, every day. No drain calls between jobs. No faucet installs in the afternoon. Just water heaters — tank and tankless, gas and electric, installation and repair.
That focus compounds. Our technicians see the same problems repeatedly, diagnose faster, and install more efficiently. They know the exact specs of every major brand, the common failure modes for Chattanooga's water conditions, and the Hamilton County permit requirements by heart.
What That Means for You
Faster, Cleaner Installs
A technician who does this every day doesn't fumble with fittings or second-guess sizing. Most standard tank replacements take 2–3 hours. Tankless conversions — including gas line and venting — are typically done in a day.
Units in Stock
Because water heaters are all we do, we keep common 40 and 50-gallon tanks (gas and electric) and popular tankless models in stock. When your unit dies on a Tuesday morning, we're not ordering one — we're loading one on the truck.
Permit Knowledge
Hamilton County requires a permit for every water heater replacement. We pull it, we schedule the inspection, we handle the paperwork. Every install we do is code-compliant — no shortcuts, no callbacks.
Honest Repair vs. Replace Advice
We don't push replacements when a repair makes sense. If your unit is under 8 years old and the fix is straightforward, we'll repair it. If it's past its prime or the repair cost approaches replacement territory, we'll tell you that too — with numbers, not pressure.
Built for Chattanooga's Water Conditions
Chattanooga's water comes from the Tennessee River via the Chattanooga Waterworks system. At 71 mg/L (4.2 grains per gallon), it's classified as moderately hard — enough to cause mild mineral accumulation inside your water heater tank over time and enough to require annual descaling on tankless units.
We factor local water conditions into every recommendation. Tank water heaters here hold up reasonably well, but they still benefit from periodic flushing. Tankless units need annual descaling to maintain efficiency and keep the warranty valid. We know this because we see the inside of Chattanooga water heaters every day — not because we read it in a manual.
Your utility provider is EPB (Electric Power Board of Chattanooga) — the same EPB that built America's first citywide gigabit network. Their competitive electric rates make electric tankless units a strong option for many Chattanooga homes, and we can walk you through the math on your specific setup.
Our Service Area Commitment
Hamilton County, Tennessee
Chattanooga proper and every community in the county — Hixson, Signal Mountain, East Ridge, Red Bank, Soddy-Daisy, Ooltewah, and surrounding neighborhoods. This is our home base and where the majority of our work happens.
Bradley County, Tennessee
Cleveland, TN and surrounding areas. Worth noting: Cleveland's water is harder than Chattanooga's at 95 mg/L (6.0 GPG), which means water heater maintenance and replacement timing differ slightly from what you'll see in Hamilton County.
Northwest Georgia
Fort Oglethorpe, Ringgold, Rossville, and Dalton aren't afterthoughts — they're part of our core service area. We serve Catoosa, Walker, and Whitfield counties with the same inventory, same-day availability, and pricing as our Tennessee customers.
Licensing and Credentials
Fully licensed to perform plumbing and water heater work throughout the state of Tennessee.
Every installation includes the required Hamilton County building permit. We handle the application and inspection scheduling.
Full liability and workers' compensation insurance on every job. Your home is protected.
Our technicians are trained on all major brands — Rheem, Bradford White, A.O. Smith, Rinnai, Navien — so your warranty is always intact.
