Water Heater Repair in Hudson, NH

62% of households in Hudson 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

The fuel a town runs on decides which faults are possible, and Hudson runs mostly on gas, at 62% of households. That figure is house heating rather than water heating, but the two rarely disagree under one roof. Gas heaters go wrong at the burner end: pilot, thermocouple, control valve, flue.

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 Hudson runs on

A gas town, and clearly so. The parts that fail on a gas heater are the pilot assembly, the thermocouple that proves the flame, and eventually the gas control valve itself.

Fuel	Share of households
Gas — mains and bottled	62%
Electricity	9%
Fuel oil and kerosene	24%
Everything else	4%

Figures from the US Census Bureau's American Community Survey, 5-year estimates, table B25040, 2023 release, covering 9,752 occupied housing units across Hudson.

The New Hampshire average is 20 points higher, so the state figure would mislead you about this town.

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

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

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

Nearby towns, and what they burn

Fuel is not uniform across a region. Four of the nearby towns we route lead on something other than gas, which is why a diagnosis that fits one town does not travel.

Temple 54% fuel oil
Fitzwilliam 59% fuel oil
Brookline 47% gas
Alton Bay 63% fuel oil
Goffstown 54% fuel oil

Know the fuel and the symptom? That is most of the call.Gas and electric heaters fail in almost entirely different ways, so saying which you have gets you to the right person faster. We route the call and never charge you for it. Whatever else is wrong in Hudson, mention it while we have you.
