A contractor called out to repair a water heater in Orleans Parish starts with the heating elements and thermostats, because those are the parts that cycle every day in an all-electric home. Electricity heats more occupied homes in Orleans Parish, Louisiana than any other fuel, at 61.4% (2020-2024 ACS 5-year). That share of the housing stock means electric resistance water heaters are far and away the most common thing a technician opens up here. Sediment buildup accelerates element failure, and in a home where the water heater is the only fuel-burning appliance, a failed element is also the homeowner's only source of hot water.
Half the homes in Orleans Parish, Louisiana were built in 1960 or earlier (2020-2024 ACS 5-year). A water heater in a house this age sits inside a history of small decisions: a flue rerouted around a renovation, supply lines replaced with whatever was available at the time, a pressure relief discharge that drains nowhere useful. When a contractor opens the area around the unit, what takes time is not the heater itself but what connects it to the house. Corroded fittings, venting that no longer meets code, or sediment in lines that run further than expected can each change the scope of the job before a part has been ordered.
The Parts of a Water Heater a Contractor Checks First
The tank is the centerpiece of the system, usually standing in a utility closet, garage, or basement. It holds the stored water and takes the first hit when something breaks down. The burner assembly or heating element at the base is where a contractor looks when the water stops getting hot.
The pressure relief valve sits on the side of the tank and releases pressure if it climbs too high. A contractor checks it early because a stuck or weeping valve is a common source of leaks. The dip tube, anode rod, and supply lines each connect the tank to the rest of the house and all of them can degrade over time.
