Water Heater Repair in Rockville, MD
61% of households in Rockville 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
Rockville runs on gas: 61% 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. On a gas heater the suspects are the pilot, the thermocouple and the gas control valve, in that order.

What Rockville runs on
With gas clearly ahead, a cold tank usually means the burner never lit — not that the heater has worn out.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 61% |
| Electricity | 38% |
| Fuel oil and kerosene | 1% |
| Everything else | 1% |
US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 57,555 occupied housing units in the ZIP code areas that cover Rockville.
That sits 14 points higher than the Maryland average, which is why we publish the town figure rather than the state 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
Not sure which you have? A metal flue rising off the top is a gas heater. Two small access panels on the side and no flue is an electric one. Settle that one question and the rest of the conversation is straightforward.
Next comes what it is actually doing. A rumbling tank is sediment; a short supply usually names the failed part; a leak decides itself.
