Water Heater Repair in Loudon, NH

46% of households in Loudon 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

The fuel a town runs on decides which faults are possible, and Loudon runs mostly on fuel oil, at 46% of households. That figure is house heating rather than water heating, but the two rarely disagree under one roof. 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 Loudon runs on

Fuel oil leads in a mixed town. Some houses here make hot water off the boiler rather than in a heater of their own.

Fuel	Share of households
Gas — mains and bottled	37%
Electricity	2%
Fuel oil and kerosene	46%
Everything else	15%

Figures from the US Census Bureau's American Community Survey, 5-year estimates, table B25040, 2023 release, covering 2,254 occupied housing units across Loudon.

That is 15 points lower than New Hampshire as a whole, which is a real difference rather than a rounding one.

It is worth being precise: this counts home heating fuel. It predicts the water heater well and does not measure it, and no published table measures it directly.

Propane rather than mains gas

Bottled and tank gas lead mains gas here. Before assuming a fault, check the tank — running out is the commonest no-hot-water cause on propane and costs nothing to rule out.

Bottled and tank gas accounts for 26% of households here against 11% 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.

Take the symptom next: no hot water, too little, rumbling, or leaking — only the last one is an emergency.
