A water heater installation in Chatham County carries a local variable that a catalog spec sheet does not capture. 343 severe weather events were recorded in Chatham County, Georgia between 2015 and 2024. At that rate, severe weather is part of the normal operating environment for any system in this area, and a contractor quoting a new unit has to factor in what that sustained load asks of the equipment over its life. That shapes which models get specified and how the installation is set up, not as a precaution but as a baseline.
The plumbing and venting already in a Chatham County home reflect decisions made for whatever water heater came with the house, and that original equipment is almost certainly gone. Half the homes in Chatham County, Georgia were built in 1986 or earlier, and half in 1986 or later (2020-2024 ACS 5-year). When a contractor prices a new installation, what drives the job is whether the existing vent path, fuel line, or electrical circuit serves the unit being installed today, not the one it was built around. A house that has already been through a water heater or two may have had those connections patched or redirected, and a new unit may not land on the same footprint.
The Parts of a Water Heater an Installation Covers
The tank is the piece a homeowner sees first, usually standing in a utility closet, basement, or garage. It holds and heats the water supply for the whole house. A gas unit has a burner assembly at the base and a flue running up through the top; an electric unit carries heating elements inside the tank walls.
The pressure relief valve mounts near the top of the tank and is connected to a discharge pipe that runs toward a drain. The cold-water inlet and hot-water outlet lines connect at the top of the tank, feeding the house's supply plumbing. A gas unit also has a dedicated gas line and shutoff valve running to the burner.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

Chatham County's weather puts real stress on water heaters over time. How hard the equipment works, and how long it lasts, is shaped by local conditions in ways that a one-size answer cannot cover.
