Tankless Water Heater in Newnan, GA

Signs that point toward tankless

• A tank installed with the house that is now well into its second decade
• Showers that go lukewarm with a full house
• A need for floor space in a garage or utility room
• Error codes or flame failures on an existing tankless unit
• Gradually weaker hot water flow

Newnan conditions

Newnan is the Coweta County seat, with a historic downtown of antebellum architecture surrounded by much newer growth along I-85. The median home was built in 2004, and about 23% predate 1980. Newer homes usually have a garage or utility room with an outside wall, where a wall-hung unit and short vent fit well. In the older homes downtown, the heater may be in a basement or closet with a flue that a sealed tankless vent cannot reuse.

Newnan Utilities provides electric, water and wastewater service. Its water comes from Line Creek, Sandy and Brown Creek and White Oak Creek, stored in reservoirs next to the plant and disinfected with chlorine and chlorine dioxide. The report does not state hardness, so a test is the way to set a flush interval. Customers in the 30263 and 30265 ZIPs outside the Newnan Utilities area may have another provider.

Gas comes through Atlanta Gas Light, which has a regional office in Newnan; Newnan Utilities does not run a gas system. Newnan Utilities does publish guidance on frozen pipes and offers a line-inspection request form, both useful if your heater sits in a garage that gets cold in January. Newnan also requires yearly testing of backflow preventers by a state-certified tester, which matters for homes with irrigation but does not change the heater install.

What affects the cost

• Gas line size from the AGL meter to the unit
• Vent length and exit point
• Condensate drain for a high-efficiency model
• Unit capacity and recirculation for larger homes
• Electrical outlet near the unit
• City permit and inspection
