Tankless Water Heater in Canton, GA

Canton's water, homes and gas

The City of Canton treats its own water from the Etowah River at the Bobby E. Bishop Water Treatment facility, and buys a smaller share from the Cherokee County Water and Sewerage Authority and the City of Waleska. The city adds chlorine, fluoride and polyphosphate, a treatment meant to limit scaling and corrosion in pipes. That is helpful, but it is not a replacement for flushing a tankless heat exchanger on the maker's schedule, and the report does not list hardness.

Canton grew quickly after 2000. The median home was built in 2005 and only about 13% predate 1980, so garages and utility rooms with an outside wall are common, which keeps vent runs short. Older houses near downtown and the Etowah River are the exception: a heater in an interior closet may need a longer vent route and a fresh look at the gas pipe.

Gas comes through Atlanta Gas Light, the only operator Georgia 811 lists for Cherokee County. Permits go through Canton Building and Safety Services and its online portal.

Seasonal notes

Canton sits in the foothills, and winter water arriving at the house is colder than in summer, so a unit sized for July may come up short in January. If the heater is in an unheated garage, ask about freeze protection and how to drain the unit if power is out during a hard freeze. If you smell gas at any time, leave first, then call 911 and Atlanta Gas Light at 877.427.4321 from outside.
