A contractor quoting a water heater replacement here starts with the electrical supply before anything else. Electricity heats more occupied homes in Florence County, South Carolina than any other fuel, at 83.3% (2020-2024 ACS 5-year). With electricity running the water heaters in the overwhelming majority of occupied homes, the service panel, the circuit amperage, and the wire gauge already in place all shape what a new unit can be. A tank that draws more current than the existing circuit supports means an electrician before the plumber finishes. Sizing the heater to the household load matters, but the wiring has to back it up.
Ductwork laid out for an earlier generation of equipment shapes what a water heater installation actually costs here more than the unit itself does. Half the homes in Florence County, South Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor pricing the job has to look at what the existing runs will carry, not just what the new unit requires, because those two things often do not match in stock of this vintage. The electrical side carries the same question: service panels in houses of this age were sized for a different load, and whether a new water heater fits that without an upgrade is something that gets measured on site, not assumed.
What a Water Heater Installation Covers
The tank or tankless unit is the heart of the system. A storage-tank water heater sits in a utility room, basement, or garage and holds a reservoir of heated water ready for use. A tankless unit mounts to a wall and heats water as it passes through, taking up far less floor space.
Running alongside the unit are the cold-water inlet line, the hot-water outlet line, and a pressure relief valve mounted directly on the tank. A dedicated gas line or electrical supply feeds the burner or heating element, and a flue or exhaust vent carries combustion gases out of the house where a gas unit is installed.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires in your home.
