Erie County winters are hard on a water heater
Buffalo winters run long. Homes here need heat from October through May, eight months of the year, and the water heater is working the whole time to bring cold groundwater up to temperature. Nights average 19°F from December through February, and a tank that's already straining against that cold is more likely to show a bad thermocouple, a failing heating element, or a tank leak right when you need hot water most.
Winter storms are common here too, 45 of them over the past ten years, along with 241 damaging wind events. Storms knock out power, and across New York, 11 percent of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep running through an outage. One with electric ignition will not relight until power comes back, and if it does not restart on its own, that's usually a sign something else needs a look.

A new water heater would cut about $90 a year off hot water for a typical New York 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 from the inside and is starting to fail. Water heaters have a steel tank with a glass lining, and once that lining cracks the steel underneath corrodes until it gives way. A leak can also come from the drain valve, a loose fitting, or the temperature and pressure relief valve, and those can sometimes be fixed. But if the water is coming from underneath the tank itself, that means the tank is done and 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 supplying gas. When it wears out it can't sense the flame properly, so the gas valve shuts off the pilot as a safety measure. A dirty pilot orifice or a draft blowing on the flame can cause the same thing. A contractor can test the thermocouple and replace it, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be repaired without replacing the unit. Common issues include a buildup of mineral scale on the heat exchanger, a faulty igniter, a clogged inlet filter, or an error code pointing to a specific sensor. A contractor can diagnose which part is causing the problem and repair or replace just that part in most cases.
