Water Heater Repair in Plaistow, NH

48% of households in Plaistow 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

In Plaistow the dominant heating fuel is gas, at 48% of households, which narrows what can be wrong before anybody opens a panel. It measures house heating, so it predicts the water heater rather than reporting it. 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 Plaistow runs on

Gas leads here but not by much, which matters: the two kinds of water heater fail for completely different reasons, and the first useful question at your address is which one you actually have.

Fuel	Share of households
Gas — mains and bottled	48%
Electricity	4%
Fuel oil and kerosene	45%
Everything else	2%

Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 3,180 occupied housing units across Plaistow.

That is 13 points higher than New Hampshire as a whole, which is a real difference rather than a rounding one.

Read that as a strong indicator rather than a measurement of water heaters. The Census counts what heats the house; what heats the water usually follows it, and occasionally does not.

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.

From there the symptom decides the rest: none at all, not enough of it, a tank that rumbles, or water on the floor, which is the one that will not wait.
