What winter here does to a water heater
Groundwater runs cold from December through February, on nights that average 25°F. Your water heater has to work harder to hit the same setpoint, and the burner or heating element runs longer to make up the difference. That extra runtime wears on the thermostat and the heating element first. Water that used to get hot fast starts taking longer, or runs out sooner than it used to.
Washington County has had 21 winter storms in the last ten years, and across Maryland 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps running through an outage. One with an electronic igniter will not, but it should come back on by itself once power returns. If yours does not, that is worth a call.

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 the tank itself has rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over the years, and it traps water against the steel until it corrodes a hole. A leak can also come from the drain valve or a fitting that has loosened, which is a much simpler fix than a cracked tank. A contractor needs to look at where the water is actually coming from before you know which one you have.
- 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 lit, so the gas valve shuts it off. Dirt or dust on the pilot opening can cause the same problem by starving the flame. A draft near the water heater can also blow the pilot out repeatedly. If you have already tried relighting it and it will not hold, the thermocouple is the part most likely to need replacing.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is common and can be flushed out, and parts like the igniter, flow sensor, or exhaust vent can be replaced when they fail. A contractor will need to run a diagnostic to read any error code the unit is showing before knowing which part is causing the problem.
