Water Heater Repair in Somerville, MA

74% of households in Somerville 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

74% of Somerville households burn gas for heat, and a water heater almost always sits on whatever line the furnace already uses. That is house heating fuel, so read it as a strong hint rather than as a reading of your own tank. 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 Somerville 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	74%
Electricity	18%
Fuel oil and kerosene	6%
Everything else	2%

Figures from the US Census Bureau's American Community Survey, 5-year estimates, table B25040, 2023 release, covering 35,295 occupied housing units across Somerville.

That sits 15 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. 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.

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.

Swampscott 69% gas
Boston 51% electricity
Melrose 64% gas
Topsfield 47% gas
Cambridge 66% 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. Whatever else is wrong in Somerville, mention it while we have you.
