Electric water heaters dominate here. Electricity heats more occupied homes in Florence County, South Carolina than any other fuel, at 83.3% (2020-2024 ACS 5-year). Most of that installed base runs on resistance elements, and those elements accumulate scale, draw down their anode rods, and eventually fail at the thermostat or the element itself. A contractor on a repair call in Florence County works through that list in order: test the element, pull the anode, check the thermostat, then trace back to the supply voltage if the first three clear. The tank itself outlasts all of it, which is why repair is almost always the right call before replacement gets priced.
Water heater systems in houses this old are often running on components that have already cycled through one or more replacement generations, which means the part a contractor pulls out may belong to a line that has been superseded or discontinued. Half the homes in Florence County, South Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). A technician who opens the unit and identifies the fault still has to confirm that a replacement part exists in the current supply chain before the repair scope is settled. When it does not, the decision shifts from fixing the existing system to specifying a new one, and that is a different job with a different price.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank is the centerpiece of the system, typically standing in a utility closet, basement, or garage, and its job is to hold and heat a supply of water ready for the rest of the house. The burner assembly or heating element sits at the base of the tank and is where heat is produced. When the water runs cold or the unit cycles oddly, those are the first places a contractor looks.
The pressure relief valve mounts to the side of the tank and releases pressure if it climbs too high, while the anode rod runs down through the interior and slows corrosion of the tank walls. The dip tube carries cold water in at the top and routes it to the bottom so it heats before it rises. The thermostat controls the target temperature and is a frequent source of erratic behavior.
