Beaufort County storms take out power more than the cold takes out heat
Winter here is short. Only five months, November through March, call for any heat at all, and even then nights average 42°F. A water heater on this island spends most of the year just holding water warm, not fighting a hard freeze.
The bigger risk is what happens when the lights go out. Nearly half of South Carolina households lost power for a full day or more in 2024, and this county has logged 304 damaging wind events over the past ten years. An electric water heater does nothing until power comes back, and most tanks pick up on their own once it does. If yours does not, or the water never gets hot again after an outage, something in it failed. That is not the power's fault.

A new water heater would cut about $300 a year off hot water for a typical South Carolina 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 cause is the tank itself, rusted through from the inside after years of sediment sitting at the bottom. Once the tank wall is breached, no fitting or valve tightening will stop it, since the steel itself has failed. It can also be a loose drain valve or a failed temperature and pressure relief valve dripping down the side and pooling underneath, which looks the same but is easy to fix. A contractor can tell the difference by drying the tank off and watching where the water first shows up.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple or flame sensor has worn out and can no longer tell the gas valve that the pilot is lit, so the valve shuts the gas off. A dirty pilot orifice or a draft in the area around the water heater can also blow the flame out or keep it too weak to hold. If you've already tried relighting it more than once and it keeps going out, the part needs to be replaced rather than adjusted. A standing pilot doesn't use any electricity, so a power outage isn't the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable, including a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code from a sensor. Tankless units run hotter and rely more on clean water and clear venting than tank models, so scale buildup shows up as a repair more often. A contractor can read the error code the unit is showing and tell you whether it's a part swap or a descaling job.
