Cold groundwater keeps your water heater working most of the year
Water heaters in Catawba County work against cold incoming water for seven months, October through April, when winter nights average 31°F. The colder that water comes in, the longer the burner or the heating element has to run to bring a tank up to temperature. That extra runtime wears on the thermostat and the heating element in an electric water heater, or the burner assembly and thermocouple in a gas one.
Power loss adds to the problem. Across North Carolina, a quarter of households lost power for at least 24 hours in 2024, and this county has recorded 9 winter storms and 66 damaging wind events over the past ten years. A gas water heater with electronic ignition needs power to relight after an outage, and a tank left cold for a day loses stored heat that takes time to recover.

A new water heater would cut about $300 a year off hot water for a typical North 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?
- Most of the time this means the tank itself has failed, and that means replacement, not repair. Water heaters rust from the inside out over years of use, and once the tank wall gives way there is no patch that holds. Before you assume the worst, check that the leak isn't coming from a loose drain valve or a fitting above the tank, since those can sometimes be tightened or replaced. If water is pooling right under the tank and nowhere else, a contractor can confirm whether it is the tank or something simpler.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually a sign the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep supplying gas. When it fails, the valve shuts off the gas as a safety measure even though the flame was there a second ago. A dirty pilot orifice or a draft blowing out the flame can cause the same symptom, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a clogged inlet filter, mineral scale built up on the heat exchanger, or an ignition sensor that needs cleaning or replacing. Tankless units also run diagnostic codes on a display, which tells a contractor what's wrong faster than guessing. A full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
