What Philadelphia winters do to a water heater
Your water heater works harder from October through April, when the water coming into the tank is already cold and winter nights average 27°F. The burner or heating element has to run longer to make up that difference, and it does this for seven months straight. That extra runtime wears on the thermostat and the heating element in an electric tank, or the burner assembly and thermocouple in a gas one.
Pennsylvania also sees real power loss. About 15% of households here went at least 24 hours without power in 2024, and the county has logged 151 damaging wind events and 15 winter storms over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with an electric ignition will not light until power is back, and most units come back on their own once it is.

A new water heater would cut about $70 a year off hot water for a typical Pennsylvania 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 of the time this means the tank itself has rusted through and is failing. Sediment builds up on the bottom of the tank over years, and it wears through the steel from the inside until water starts to seep out. A loose drain valve or a fitting can also leak and look like the tank is the problem, so it is worth checking those first. If the tank itself is leaking, it needs to be replaced, not repaired.
- 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 is safe to keep gas flowing. When it wears out, it fails to sense the flame properly and shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it too weak to register. A contractor can test the thermocouple and replace it if that is the issue.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or a bad flow sensor can usually be fixed without replacing the unit. Because tankless units run on electronic controls, a contractor needs to pull the error code from the display to know exactly what part has failed. Whether repair makes sense over replacement depends on the age of the unit and what's actually wrong with it.
