Water Heater Repair in New London, NH

44% of households in New London 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

Most households in New London heat with gas — 44% of them — which is the strongest free clue to what stands in the basement, though the figure counts house heating rather than the water heater itself. 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 New London runs on

Gas is the largest share rather than the norm. Check your own tank before drawing on what a neighbor was told.

Fuel	Share of households
Gas — mains and bottled	44%
Electricity	7%
Fuel oil and kerosene	40%
Everything else	8%

Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 1,628 occupied housing units across New London.

That is 22 points lower than New Hampshire as a whole, which is a real difference rather than a rounding one.

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.

Propane rather than mains gas

More households here run bottled or tank propane than mains gas, which changes two things: propane burners use different orifices from natural gas, and a tank that has run dry produces a no-hot-water call that mains gas can never produce.

Bottled and tank gas accounts for 41% of households here against 3% on mains gas.

Which one do you have

Check for a flue. Gas heaters vent; electric heaters have nothing to vent and carry element access panels on the side instead. 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.
