Gas water heaters make up the overwhelming majority of units in this county. Utility gas heats more occupied homes in Gloucester County, New Jersey than any other fuel, at 77.9% (2020-2024 ACS 5-year). When a water heater stops delivering, a contractor working on gas equipment checks the thermocouple and the gas valve before anything else, because those components are what the combustion cycle runs on. Sediment builds in the tank as the burner cycles, and a failed ignition system or a venting problem that would be unremarkable in an all-electric home becomes the first place a contractor opens the service call here.
Older plumbing runs and electrical feeds that were sized for a different kind of water heater are what a contractor often has to sort out before the repair itself can be priced or finished. Half the homes in Gloucester County, New Jersey were built in 1980 or earlier (2020-2024 ACS 5-year). That matters for repair work because the lines feeding a water heater in a house of this vintage may not match what the current unit draws or requires, and when a contractor opens the access or pulls the unit, those conditions change what the job is. A part swap that looks straightforward from the outside can hinge on what the surrounding infrastructure will actually support.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank itself is the piece most homeowners know: a large insulated cylinder that sits in a utility room, basement, or garage and holds water at a set temperature. When a tank is the problem, a contractor looks at the outer shell, the internal lining, and the pressure relief valve, which is the safety device mounted to the tank's side.
The burner assembly or heating element sits inside or beneath the tank and is what actually raises the water temperature. The thermostat controls that process, and the anode rod runs down into the tank to slow corrosion. The dip tube carries cold water in, and the outlet at the top carries hot water out to the rest of the house.
The drawing shows a typical water heater layout, and a licensed contractor determines what applies to the specific unit and setup in your home.
