Water Heater Repair in Candia, NH

64% of households in Candia 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

64% of Candia households burn fuel oil 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. An oil-fired system puts a burner, a nozzle and a service contract into the picture.

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 Candia runs on

A fuel-oil town. Indirect water heating is common in these houses, and that makes the boiler part of the diagnosis rather than a separate machine.

Fuel	Share of households
Gas — mains and bottled	21%
Electricity	5%
Fuel oil and kerosene	64%
Everything else	9%

US Census Bureau, ACS 5-year estimates 2023, table B25040 (house heating fuel). Based on 1,559 occupied housing units in the ZIP code areas that cover Candia.

That is 25 points lower than New Hampshire as a whole, which is a real difference rather than a rounding one.

Strictly, the survey asks what heats the home. Water heating almost always runs on the same supply, but the two can differ in one house without differing in the town.

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 21% of households here, and the survey records none at all on mains gas.

Which one do you have

The quick test is the top of the tank. A vent pipe means combustion; no vent means elements. The fuel decides the fault list, so start there rather than with the symptom.

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

Nearby towns, and what they burn

Hampton 60% gas
Merrimack 57% gas
Francestown 46% fuel oil
Greenfield 37% fuel oil
Hampton Falls 60% fuel oil
