Ruston's cold nights and power outages both take a toll on your water heater
Winter nights here average 37°F from December through February, and colder water coming in means your water heater has to work harder to keep up. That extra work falls on the heating element or the burner, and either one can wear out sooner because of it.
Lincoln Parish has logged 51 damaging wind events and 5 winter storms over the past ten years, and in 2024 nearly half of Louisiana households lost power for a full day or more. An electric water heater stops heating the moment the power drops, and most come back on their own once it returns. If yours didn't, or the water isn't as hot as it should be after an outage, that's usually why.

A new water heater would cut about $250 a year off hot water for a typical Louisiana home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common reason is that the tank itself has rusted through and is failing. Sediment builds up on the bottom of the tank over years, and it eats away at the steel underneath. A leak from the bottom usually means the tank needs to be replaced, not repaired, since there's no way to patch a hole in the liner. Water pooling underneath can also come from a loose drain valve or a fitting that's just working its way loose, so it's worth checking those before assuming the worst. A contractor can tell you which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is burning. The thermocouple is a safety switch that shuts off the gas if it doesn't detect a flame, and once it weakens it will cut the gas even when the pilot is lit. A dirty pilot tube or a draft blowing across the flame can cause the same thing, so the fix isn't always the same part. A gas water heater needs a licensed contractor to diagnose this, since it involves the gas line and the burner assembly.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. The heat exchanger, the igniter, and the flow sensor are the parts that fail most often, and each one can be replaced on its own. Mineral buildup inside the heat exchanger is common too, especially if the unit has never been flushed, and that's a service job rather than a replacement. A contractor licensed in Louisiana can open the unit and tell you which part is causing the problem.
