Water Heater Repair in Potomac, MD
70% of households in Potomac 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 Potomac heat with gas — 70% 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. A gas unit fails at the pilot, the thermocouple, the gas control valve, or a flue that will not draft.

What Potomac runs on
In a town leaning this far onto gas, the heater is usually a burner with a tank above it. What fails is the ignition chain rather than anything electrical.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 70% |
| Electricity | 24% |
| Fuel oil and kerosene | 5% |
| Everything else | 2% |
Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 16,542 occupied housing units across Potomac.
Against Maryland as a whole, that is 22 points higher — worth knowing before assuming the state pattern applies here.
Read that as a strong indicator rather than a measurement of water heaters. The Census counts what heats the house; what heats the water usually follows it, and occasionally does not.
Which one do you have
The quick test is the top of the tank. A vent pipe means combustion; no vent means elements. 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.
