Water heaters in Tennessee: what to know
MLGW in Memphis and KUB in Knoxville also provide gas, so gas heater installs connect to those utilities.
Replacements need a permit. A drain pan helps.
Older homes in Memphis's Midtown and Knoxville's Fourth and Gill may have heaters in crawl spaces or tight closets with venting that needs updating. Ice storms can also cause outages that leave electric heaters cold. Annual flushing helps tanks last.
- Climate
- Tennessee gets periodic hard freezes and ice storms, often after mild spells, which catch exposed pipes off guard. Pipes in crawl spaces, exterior walls and garages are the first to freeze.
- Typical foundations
- Crawl spaces are common, along with basements in hilly areas, and many rural homes rely on septic systems. Most common: basements, crawl spaces.
Water heaters services
Water heater repair
If a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat. Those parts are repairable. A tank that leaks from the bottom can't be repaired and needs to be replaced.
Water heater replacement
A leaking tank or a heater past about 10 years old is usually replaced rather than repaired. A proper install includes a permit, correct venting (adjusted for altitude where needed), an expansion tank where required, a drip leg on the gas line and a relief valve discharge pipe.
Tankless water heaters
A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation. Installed correctly and descaled regularly, it can outlast a tank heater.
