Water Heater Repair in Medford, MA

65% of households in Medford 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

The fuel a town runs on decides which faults are possible, and Medford runs mostly on gas, at 65% of households. That figure is house heating rather than water heating, but the two rarely disagree under one roof. A gas unit fails at the pilot, the thermocouple, the gas control valve, or a flue that will not draft.

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 Medford runs on

A gas town, and clearly so. The parts that fail on a gas heater are the pilot assembly, the thermocouple that proves the flame, and eventually the gas control valve itself.

Fuel	Share of households
Gas — mains and bottled	65%
Electricity	18%
Fuel oil and kerosene	15%
Everything else	2%

US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 24,586 occupied housing units in the ZIP code areas that cover Medford.

That sits 7 points higher than the Massachusetts average, which is why we publish the town figure rather than the state one.

Strictly, the survey asks what heats the home. Water heating almost always runs on the same supply, but the two can differ in one house without differing in the town.

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.

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.

Nearby towns, and what they burn

Fuel is not uniform across a region. One of the nearby towns we route lead on something other than gas, which is why a diagnosis that fits one town does not travel.

Attleboro Falls 56% fuel oil
Groveland 66% gas
Andover 67% gas
Bedford 68% gas
Bridgewater 44% gas

Know the fuel and the symptom? That is most of the call.Gas and electric heaters fail in almost entirely different ways, so saying which you have gets you to the right person faster. We route the call and never charge you for it. The line covers more than water heaters in Medford.
