Kent County winters put your water heater to work
Groundwater coming into your house is cold for seven months of the year, December through February nights here average 28°F. Your water heater has to work harder and longer to bring that water up to temperature, and it runs more often to keep up. That extra cycling wears on the heating element or burner assembly and on the thermostat that controls it.
Kent County has seen 98 damaging wind events and 8 winter storms over the past 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 will keep working through an outage. One with an electric igniter or an electric unit will not come back on until power is restored, and most will restart on their own once it is.

A new water heater would cut about $370 a year off hot water for a typical Maryland 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 often the tank itself has rusted through and is holding water that seeps out at the seam or a fitting. Sediment builds up in the bottom of the tank over the years, and it wears through the lining from the inside until the steel underneath gives way. Once a tank is actually leaking like this, it needs to be replaced, not patched, because the tank cannot be repaired once it has rusted through. It is worth checking first that the water is really coming from the tank and not from a loose fitting, the temperature and pressure relief valve, or a drain valve that is not seated all the way, since those can be fixed without replacing anything.
- 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. When that happens the pilot lights but the valve shuts the gas back off within seconds, so it never stays lit. A weak or dirty pilot flame, a draft blowing across it, or a gas valve that is failing can cause the same thing. A thermocouple is inexpensive to replace, but if the pilot still won't hold after that, the gas valve itself may need replacing, and that is a job for a licensed contractor.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, an ignition fault, or a sensor reporting a fault code, and all of these can usually be fixed without replacing the unit. The error code on the display is usually the fastest way to point a contractor to what is wrong. Replacement is only needed if the heat exchanger itself has failed, which is less common than the parts around it failing first.
