What Pittsburgh winters do to a water heater
Your water heater works harder here than the label suggests. Groundwater coming into the tank is already cold from the winter air, and from October through May the burner or element has to work that much longer to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in an electric unit, or the burner assembly and thermocouple in a gas one.
Allegheny County also loses power sometimes. Statewide, 15% of households went at least 24 hours without it in 2024, and the last ten years brought 12 winter storms and 548 damaging wind events. A gas water heater with a standing pilot will keep making hot water through an outage, but one with an electric ignition won't relight on its own. If your water was hot before the power went out and cold after, that's usually why.

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 often the tank itself has rusted through, and once that happens the tank has to be replaced, not repaired. The other common cause is a fitting or valve above the tank dripping down the side, which can look like a bottom leak but often isn't. If you see water pooling under the tank, shut off the water supply to the heater and the gas or power to it, then have someone look at it before it fails completely. A contractor can tell you quickly whether it's the tank or something upstream of it.
- Why won't the pilot light on my water heater stay lit?
- This usually means the thermocouple has worn out. That's the small part that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. When it wears out, it can't sense the flame properly anymore, so the valve shuts off the gas even though the pilot lit fine a moment ago. It's a straightforward part to replace and doesn't mean anything else is wrong with the water heater.
- Can a tankless water heater be repaired?
- Yes, in most cases. The heat exchanger, the igniter, and the flow sensor are the parts that fail most often, and all of them can be replaced without swapping out the whole unit. Mineral buildup inside the heat exchanger is common too, and flushing the unit clears that. A contractor can open it up and tell you which part is causing the problem you're seeing.
