Cold groundwater and power loss both take a toll here
Frederick County winters push your water heater harder for seven months straight. Groundwater coming into the tank is colder, so the burner or heating element runs longer and more often to keep up. That extra run time wears on the thermostat and the heating element in an electric unit, or the burner assembly and thermocouple in a gas one.
Power doesn't always stay on through it. Statewide, 11% of households lost power for a full day or more last year, and this county has logged 23 winter storms and 276 damaging wind events over the past decade. An electric water heater goes cold the moment power drops, and some units need to be reset once it's back. If yours isn't heating, or the water runs out fast, or you hear the tank straining to keep up, that's what's likely being asked of it right now.

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 from the inside and is cracked. Water heaters aren't built to be repaired at the tank, so once it's leaking there, the tank needs to be replaced. Sometimes what looks like a bottom leak is actually the drain valve or a fitting above it, with water running down the side and pooling underneath, so it's worth checking those first before assuming the tank is done.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to stay open. When it wears out it can't hold that signal, so the gas shuts off and the flame dies. A dirty pilot orifice or a draft blowing the flame around can cause the same thing, and a contractor can tell which one it is by watching how the flame behaves when it's lit.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues, and each of those can be cleaned or replaced without swapping out the whole unit. Whether it's worth repairing versus replacing depends on the age of the unit and what's actually failed, which a contractor can tell you after looking at it.
