Sussex County winters push your water heater harder
From October through April your water heater works against cold groundwater for seven months straight. On nights that average 29°F, it has to run longer to bring water up to temperature, and that extra runtime wears on the heating element or burner assembly.
Power is part of the problem too. Twelve percent of Delaware households went at least a full day without power in 2024, and the county has seen 17 winter storms and 198 damaging wind events over the past ten years. When the power drops and comes back, a gas water heater with an electronic ignition needs that ignition to relight the burner, and an electric water heater needs its heating elements to draw power again. If either one fails to reset, you are left with a tank full of cold water and no hot water until it is looked at.

A new water heater would cut about $370 a year off hot water for a typical Delaware 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 failing. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath corrodes and eventually leaks. A leak can also come from the drain valve, a loose fitting, or the temperature and pressure relief valve doing its job because the tank is overheating. If the leak is from the tank itself, the water heater needs to be replaced, not repaired, since a leaking tank can't be sealed.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the cause. It's a small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. When it wears out or gets coated with soot, it reads the flame wrong and shuts the gas off, so the pilot goes out. A weak pilot flame, a draft near the burner, or a failing gas control valve can cause the same thing. A contractor can test the thermocouple and replace it, since a standing pilot needs no power to run and will burn as long as the gas and the sensor are working.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a clogged inlet filter, buildup on the heat exchanger from hard water, a bad igniter, or an error code pointing to a sensor. A contractor can flush the unit, clean or replace the part causing the fault, and reset it. Only if the heat exchanger itself has failed does replacement usually make more sense than repair.
