Plumbing Water Heater Replacement in Tennessee
Replacement of a failed or aging water heater with a new tank, tankless, or heat-pump unit — Rheem, Bradford White, A.O. Smith, or Navien — sized to your household, installed to code with a new expansion tank and shut-off, and the old unit hauled away.
Water Heater Replacement is one part of our water heater services coverage in Tennessee. For the full picture — symptoms, costs, and when to repair vs. replace — start with the complete Water Heater Repair guide, or browse every water heater services service we offer.
When a water heater rusts through, runs cold, or simply reaches the end of a 10-to-15-year life, replacement is the point where you make decisions that stick for the next decade — fuel type, capacity, and whether to stay with a tank or move to tankless or heat-pump. We replace failed and aging units with the right one for your home, not just whatever matches the old footprint, and we do it to current code with the safety hardware — a new shut-off, a properly sized expansion tank, a code-length T&P discharge, and correct venting — that a bare swap leaves out.
Right-sizing at replacement is the highest-leverage decision in the job. A tank that was undersized the whole time it was in the house is the reason the last shower ran cold, and replacing like-for-like just repeats the problem; an oversized tank wastes standby energy every hour. We size to your household's real peak demand — number of bathrooms, simultaneous use, tub size — and recommend by fit: a Bradford White or A.O. Smith atmospheric tank for a straightforward gas swap, a Navien or Rheem tankless when the family keeps running out of hot water, or a heat-pump hybrid where the electric operating savings justify the price across {city}.
Replacement is a same-day job in most homes, and we make it turn-key — draining and disconnecting the old unit, hauling it away for recycling, setting and connecting the new one, adding the expansion tank and shut-off, and running it up to temperature with a full leak and T&P check before we leave. Where the replacement is also an upgrade — going tankless or adding a recirculation loop — we handle the larger gas line, venting, or electrical that requires. The result is a heater sized to actually keep up, installed to last its full life across {county} and {areas}.
Signs you need water heater replacement
Heater is 10 or more years old
Tank heaters have a 10-to-15-year life and tend to fail suddenly at the end of it. Replacing an old the United States unit on your schedule beats replacing it under a flooded floor at 2 a.m.
Brown or metallic hot water means the tank lining and anode are gone and the steel itself is corroding. Once a tank rusts through there's no repair — replacement is the fix in the the United States home.
Water pooling around the base
Moisture or a puddle at the tank base is a seam leak, a slow failure headed for a flood. A leaking tank is a replacement, and catching it early avoids the water damage across your area.
Running out of hot water
If the last shower is always cold, the tank is undersized or its dip tube and elements are failing. Replacement is the moment to upsize or move to tankless for the the United States household.
Rising energy bills and a rumbling tank
Sediment baked on the bottom insulates the burner, wastes fuel, and rumbles as it heats. On an older tank it signals the last stretch before failure and a good time to replace across the United States.
Common causes & what we fix
Tank corrosion at end of life
The sacrificial anode rod is consumed over years and then the steel tank corrodes from the inside out. Most the United States homeowners never replace the rod, so the tank reaches end-of-life on a predictable schedule.
Sediment damage
Hard-water minerals settle in the tank, insulate the burner or element, and force it to overheat the steel. Heavy scale ends a the United States tank early and is a common reason for replacement.
Chronic undersizing
A tank spec'd too small for the household cycles constantly and wears out fast while never keeping up. Replacement is the chance to right-size for the your area home.
Failed dip tube or elements
A broken dip tube dumps cold water into the hot outlet and burned-out elements leave the water lukewarm. On an older the United States unit these signal it's cheaper to replace than keep repairing.
Thermal expansion with no relief
On a closed system, heating raises pressure with nowhere to go and stresses the tank every cycle. We add a correctly sized expansion tank on every the United States replacement that needs one.

Frequently asked about water heater replacement
Top questions homeowners searching for Water Heater Replacement near me ask us:
Should I repair or replace my water heater?
Under 8 years old with a minor fault — repair. Past 10–12 years, leaking from the tank, or facing a major control failure — replace. We quote both for your the United States home so you can weigh the repair cost against a new, right-sized unit.
How long does a replacement take?
A straight tank-for-tank swap runs 2–4 hours including haul-away, a new shut-off, and an expansion tank. Upgrading to tankless takes longer — 4–8 hours — because it usually needs a larger gas line and new venting across the United States.
Should I switch to tankless while I'm replacing?
It's the natural time to consider it. Tankless delivers endless hot water, lasts closer to 20 years, and frees floor space, but needs a larger gas line and venting. We size and price both a tank and a tankless for your your area home so you decide.
Do you haul away the old heater?
Yes — the old tank is drained, disconnected, removed, and recycled through metal and appliance channels. We don't leave the old unit behind after a the United States replacement.
What size heater should I get?
We size to your peak demand — bathroom count, simultaneous use, and tub size — not just the old tank's capacity. Right-sizing is why the new heater keeps up when the old one ran cold, and we serve ZIPs across the United States.
