Water Heater Repair in Reston, VA

50% of households in Reston 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 Reston burns is worth more over the telephone than any description of the symptom, and 50% 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.

HeaterRelay is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no work, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

What Reston runs on

Gas is the largest share rather than the norm. Check your own tank before drawing on what a neighbor was told.

Fuel	Share of households
Gas — mains and bottled	50%
Electricity	48%
Fuel oil and kerosene	1%
Everything else	1%

Figures from the US Census Bureau's American Community Survey, 5-year estimates, table B25040, 2023 release, covering 29,047 occupied housing units across Reston.

That is 4 points higher than Virginia as a whole, which is a real difference rather than a rounding one.

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

If you are not sure, look at the top of the tank: a flue pipe going up into the ceiling means gas, and no flue at all means electric. Establish the fuel first; almost every useful question after that depends on it.

The symptom does the rest of the work. Hot water that quits early is the most informative of them; a leak from the tank itself is the most urgent.
