Water Heater Repair in Bethesda, MD
66% of households in Bethesda 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
Knowing what Bethesda burns is worth more over the telephone than any description of the symptom, and 66% of households there heat with gas. House heating fuel predicts the water heater without proving it. Gas heaters go wrong at the burner end: pilot, thermocouple, control valve, flue.

What Bethesda 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 | 66% |
| Electricity | 31% |
| Fuel oil and kerosene | 1% |
| Everything else | 1% |
US Census Bureau, American Community Survey, table B25040, 2023 5-year release. The universe is 34,235 occupied housing units in and around Bethesda.
Against Maryland as a whole, that is 20 points higher — worth knowing before assuming the state pattern applies here.
One caveat, because it matters: the Census measures the fuel a household heats the HOUSE with, not the fuel it heats WATER with. The two track each other closely — a gas line to the furnace usually feeds the tank as well — but they are not the same number.
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. Knowing which of the two you own is the difference between a diagnosis and a guess.
With the fuel settled, read across to the symptom: none, not enough, noise, or water where it should not be.

- Boyds 63% gas
