What winter here does to a water heater
Groundwater feeding into your water heater is coldest from December through February, right when nights in Stephens City average 25°F. The unit has to work harder to bring that water up to temperature, and it runs longer to do it. That extra runtime wears on the heating element in an electric tank and on the burner assembly in a gas one.
Power is part of the picture too. Last year 22% of Virginia households lost power for 24 hours or more at some point. A gas water heater with a standing pilot will keep working through an outage, but most electric models and any gas unit with an electronic ignition will not heat water until power is back. If yours does not restart on its own once the lights come back on, that is worth a look.

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 rusted through and is failing, not something you can patch. Sediment builds up on the bottom of the tank over the years, and it traps heat against the steel until a weak spot gives way. A loose drain valve or a fitting can also leak and look the same from the outside, so it is worth checking those before you assume the tank is done. Once the tank itself is leaking, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a thermocouple that has worn out and no longer senses the flame well enough to keep the gas valve open. A draft blowing across the pilot, a dirty pilot orifice, or a bad gas valve can cause the same thing. A contractor can test the thermocouple in a few minutes and replace it if that is the problem. Winter nights here drop to around 25°F, so a water heater that keeps going out is worth fixing quickly rather than living with cold showers.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a bad igniter, a clogged inlet filter, and sensor errors are all common issues a contractor can diagnose and fix. The exchanger itself is the most expensive part to replace, so a unit is usually only replaced outright if that fails or the unit is old. Flushing the system to clear mineral scale on a regular basis is what keeps most tankless units running for years without bigger repairs.
