A contractor quoting a water heater replacement here starts with the service panel, not the unit itself. Electricity heats more occupied homes in Union County, South Carolina than any other fuel, at 58.3% (2020-2024 ACS 5-year). That share of electric-powered homes means the wiring feeding the water heater, the breaker amperage, and the panel capacity are all variables a contractor checks before ordering equipment. A water heater that draws more current than the existing circuit can carry needs an electrical upgrade alongside the install, which changes the scope and the bill. Sizing the tank without that check produces a unit the house cannot safely run.
Ductwork in a house like this was not put in for what runs in it now. Half the homes in Union County, South Carolina were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor sizing a new water heater here has to check what the existing runs can actually carry and where the electrical service lands relative to the unit's draw, because both were designed around different equipment. The routing and the panel are the job. Get those wrong and the unit itself is almost beside the point.
What a Water Heater Installation Covers
The tank or tankless unit is the centerpiece of the system. A storage-tank heater sits in a utility room, basement, or garage and holds a reservoir of hot water ready for use. A tankless unit mounts to a wall and heats water on demand as it passes through the unit.
The cold-water inlet and hot-water outlet connections run into and out of the unit, feeding the rest of the house. A pressure relief valve mounts directly on the unit as a safety device, and a drain valve sits at the base. Gas-fired models also include a flue or venting pipe that runs from the unit to an exterior exhaust point.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your house and its existing setup.

Weather puts real load on water heating equipment, and that load varies by where you live. What this county sees shapes how hard a water heater has to work and what it needs to hold up over time.
