Water Heater Repair in Exeter, NH

46% of households in Exeter 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

46% of Exeter 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 Exeter 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	46%
Electricity	14%
Fuel oil and kerosene	33%
Everything else	6%

US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 9,052 occupied housing units in the ZIP code areas that cover Exeter.

On gas, Exeter is close enough to the New Hampshire figure that the difference is inside the survey’s margin of error — so the state pattern is a fair guide here, which is not true everywhere.

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

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. Find out what your own tank burns before anyone quotes you anything.

With the fuel settled, read across to the symptom: none, not enough, noise, or water where it should not be.

Nearby towns, and what they burn

Greenland 55% fuel oil
Franklin 42% fuel oil
Atkinson 50% fuel oil
Derry 47% fuel oil
Dover 49% gas
