Replacing a water heater in Lee County starts with the electrical supply, because the panel and the dedicated circuit have to support whatever unit goes in. Electricity heats more occupied homes in Lee County, South Carolina than any other fuel, at 86.2% (2020-2024 ACS 5-year). A contractor quoting the job checks the breaker size and the wire gauge before recommending a unit, because an undersized circuit limits which models are viable and forces a separate electrical upgrade if the homeowner wants more capacity. Venting is a secondary question for most households here, since electric units do not require combustion air or a flue.
Electrical service in a house is sized at the time of construction, and the gap between what a panel was built to carry and what a new water heater actually draws is where a water heater installation job either stays simple or gets complicated. Half the homes in Lee County, South Carolina were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor working in stock that old checks the service panel early, because an undersized panel is not a side question on the quote, it is the one that changes what else gets listed. Ductwork is beside the point on a water heater job, but the electrical is not.
What a Water Heater Installation Covers
The tank or tankless unit is the heart of the system. A storage tank unit sits in a utility closet, basement, or garage and holds a ready supply of hot water. A tankless unit mounts on a wall and heats water on demand as it passes through.
The cold water inlet and hot water outlet lines connect the unit to your home's plumbing. A pressure relief valve sits on the side of the tank as a safety device, and a drain valve at the base allows the unit to be serviced. Gas-fired models also include a flue or exhaust vent that runs from the unit to an exterior termination point.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing connections.
