Cold water and power outages both take a toll
Winter nights in Hanover County average 28°F from December through February, and your water heater works harder those months to bring cold water up to temperature. The longer the burner or heating element runs, the more wear it puts on the thermocouple or the element itself, and that is when a unit that was already struggling tends to quit.
Storms add to the risk. The county has seen 23 winter storms and 84 damaging wind events over the past ten years, and statewide, 22% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot will keep heating through an outage, but an electric water heater or a gas unit with electronic ignition will not make hot water again until the power is back.

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 often the tank itself has rusted through and is failing, and no repair fixes that, it needs to be replaced. Before you assume the worst, check whether the leak is really coming from the tank or from a fitting, the drain valve, or the temperature and pressure relief valve above it, those can sometimes be repaired. A tank that's leaking from the bottom seam should be replaced soon, since it will only get worse and can flood the area around it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the flame is lit. When it fails, the valve shuts off gas as a safety measure even though the pilot was burning fine. A dirty pilot orifice or a draft blowing out the flame can cause the same thing, and a contractor can tell which one you're dealing with. This isn't something to keep relighting on your own for long, since a gas water heater with a pilot problem needs a real fix.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. A failed igniter, a clogged inlet filter, a bad flow sensor, or mineral buildup on the heat exchanger are all things a contractor can fix or clean without replacing the unit. Tankless units also run diagnostic codes on a display or through a series of blinks, which point straight to the part causing trouble. Replacement usually only comes up when the heat exchanger itself has cracked or corroded through.
