Water Heater Repair in Cohasset, MA

50% of households in Cohasset 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

Cohasset runs on gas: 50% 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.

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 Cohasset runs on

The town is mixed with gas in front. Nothing about that average tells you what is plumbed into your house.

Fuel	Share of households
Gas — mains and bottled	50%
Electricity	13%
Fuel oil and kerosene	36%
Everything else	1%

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 3,109 occupied housing units in the ZIP code areas covering Cohasset.

That sits 9 points lower than the Massachusetts 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. The fuel decides the fault list, so start there rather than with the symptom.

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.
