Water Heater Repair in Louisville, KY
61% of households in Louisville heat with gas. 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
Most households in Louisville heat with gas — 61% of them — which is the strongest free clue to what stands in the basement, though the figure counts house heating rather than the water heater itself. On a gas heater the suspects are the pilot, the thermocouple and the gas control valve, in that order.

What Louisville runs on
With gas clearly in front, most tanks here burn it. That puts the usual faults on the burner side — pilot, thermocouple, gas valve — rather than on elements and thermostats.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 61% |
| Electricity | 38% |
| Fuel oil and kerosene | under 1% |
| Everything else | 1% |
US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 323,771 occupied housing units in the ZIP code areas that cover Louisville.
That is 22 points higher than Kentucky as a whole, which is a real difference rather than a rounding one.
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
The quick test is the top of the tank. A vent pipe means combustion; no vent means elements. Settle that one question and the rest of the conversation is straightforward.
Then match what you are seeing: cold from the start, hot then cold, banging and popping, or a leak.

Nearby towns, and what they burn
Fuel is not uniform across a region. Four of the nearby towns we route lead on something other than gas, which is why a diagnosis that fits one town does not travel.
- Worthington 74% gas
- Shelbyville 49% electricity
- Hillsboro 64% electricity
- Lowmansville 78% electricity
- Greenup 51% electricity
