Water Heater Repair in Sandown, NH

46% of households in Sandown heat with fuel oil. 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

Knowing what Sandown burns is worth more over the telephone than any description of the symptom, and 46% of households there heat with fuel oil. House heating fuel predicts the water heater without proving it. Oil brings a burner and an annual service into it, which changes who you call.

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 Sandown runs on

Oil is the plurality here. That raises a question the rest of the country rarely asks — whether your hot water comes from a heater at all, or from the boiler.

Fuel	Share of households
Gas — mains and bottled	34%
Electricity	12%
Fuel oil and kerosene	46%
Everything else	8%

Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 2,223 occupied housing units across Sandown.

New Hampshire statewide runs 25 points lower on gas, so this town is not typical of it.

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 33% of households here against 1% on mains gas.

Which one do you have

If you are not sure, look at the top of the tank: a flue pipe going up into the ceiling means gas, and no flue at all means electric. Establish the fuel first; almost every useful question after that depends on it.

Then match what you are seeing: cold from the start, hot then cold, banging and popping, or a leak.
