Gas-fired water heaters carry a specific set of failure points: the burner, the thermocouple, the draft hood, and the flue. Utility gas heats more occupied homes in Hillsborough County, New Hampshire than any other fuel, at 38.4% (2020-2024 ACS 5-year). That proportion means gas venting infrastructure is widespread here, and a contractor diagnosing a water heater fault works through the combustion air supply and the vent path before concluding the appliance itself is at fault. A blocked or corroded flue can produce symptoms that look like a burner problem, and quoting a burner repair without checking the vent first puts the wrong part on the invoice.

Water heaters in houses this old are rarely first-generation. The house has outlasted several units already, and the one a contractor opens today carries its own age on top of the building's. Half the homes in Hillsborough County, New Hampshire were built in 1978 or earlier (2020-2024 ACS 5-year). That gap matters for repair work because a unit installed in an older house is not always a recent model, and when a contractor opens it, the question of whether its parts are still manufactured shapes what the job can be. A repair that would be straightforward on current equipment can become a sourcing problem when the unit predates its own part supply.

The Parts of a Water Heater a Contractor Checks During a Repair

The tank is the piece most homeowners know: a large insulated cylinder that sits in a utility closet, basement, or garage and holds water at a set temperature. The burner assembly or heating elements inside it are where a contractor looks first when the water runs cold or the unit stops responding.

The thermostat sits against the tank and tells the heating source when to fire and when to stop. The pressure relief valve mounts on the side or top and opens if pressure inside builds past a safe point. The anode rod hangs inside the tank and slows corrosion of the metal walls.

The drawing shows a typical water heater layout, and a licensed contractor determines which parts apply to the unit in your home.
