A contractor quoting a water heater installation in DeKalb County is working out what the unit will actually be asked to handle here, and that question has a specific answer. 165 severe weather events were recorded in DeKalb County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition, not an occasional disruption, and the load it places on a water heater over years is built into what the equipment faces from day one. Sizing, placement, and connection quality are all specified around that operating reality. A unit that is right for a quieter area may be undersized for this one.
Ductwork routed for an older venting standard often cannot carry a new water heater's exhaust or intake without modification. Half the homes in DeKalb County, Georgia were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing a new unit in stock this old spends as much time reading what is already in the walls and utility spaces as specifying the equipment itself. If the existing vent runs are undersized or take bends that current units cannot tolerate, the scope of the job shifts before the new unit is ever ordered.
What a Water Heater Installation Covers
The tank or tankless unit is the heart of the system, sitting in a utility closet, basement, or garage and holding or heating water on demand. A pressure relief valve mounts directly on the unit and releases pressure if it climbs too high. The supply and discharge connections tie the unit into the home's cold and hot water lines.
The flue or venting pipe exits the unit and runs to an exterior wall or roof, carrying combustion gases out of the living space. A gas line or dedicated electrical circuit feeds the unit its energy source, and a drip pan sits underneath to catch any condensation or minor leaks before they reach the floor.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your house.

Water heaters work harder when the weather outside swings hard, and Georgia's climate does not stay mild. What happens in DeKalb shapes how much a unit is asked to do, which makes local weather history relevant to any installation decision.
