Water Heater Repair in Columbia, TN
67% of households in Columbia heat with electricity. That is the strongest free clue to what kind of water heater is in your basement, and it decides which faults are even possible.
Answer first
Columbia runs on electricity: 67% of households heat that way, and that single fact rules most of the possible water heater faults in or out. The figure covers house heating rather than the tank. Electric heaters fail at an element or a thermostat, and nothing else is in the running.

What Columbia runs on
A clearly electric town, so the heater most likely has no flame, no flue and no pilot — and a different set of things that break.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 32% |
| Electricity | 67% |
| Fuel oil and kerosene | 1% |
| Everything else | 1% |
US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 25,964 occupied housing units in the ZIP code areas that cover Columbia.
Against Tennessee as a whole, that is 9 points lower — worth knowing before assuming the state pattern applies here.
That figure is house heating fuel, not water heater fuel. They correlate strongly, because the same gas line generally serves both, but the Census does not publish the second one and we are not going to pretend it does.
Which one do you have
Check for a flue. Gas heaters vent; electric heaters have nothing to vent and carry element access panels on the side instead. Establish the fuel first; almost every useful question after that depends on it.
After that it is the symptom that narrows things: nothing at all points one way, running out early another, and a puddle is the one to act on today.
