What winter here does to a water heater
Groundwater coming into your house is cold most of the year, and from September through May your water heater works against real winter to make up the difference. On nights near 10°F, a tank that cycles a few times a day in summer fires much more often just to hold temperature. That extra cycling wears on the burner assembly and the igniter, and it is often what pushes a marginal part to finally fail.
Power matters too. Most gas water heaters need power for the igniter and controls even though the fuel is gas, so an outage takes your hot water down with it. 21% of Vermont households went at least 24 hours without power in 2024, and Washington County has seen 38 winter storms and 70 damaging wind events over the past ten years. A cold snap here can knock out your hot water two ways at once.

- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through and is leaking from the inside. Sediment builds up over the years and corrodes the tank from the bottom up, and once it starts leaking that way there is no patch for it. It could also be the drain valve or a fitting near the bottom, which a contractor can check and fix without replacing the tank. Either way, shut off the water and power or gas to the unit and have someone look at it before it leaks further.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the reason. It is the sensor that tells the gas valve the pilot is burning, and once it wears out or sits out of position, the valve shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft in the closet can do the same thing. A contractor can test the thermocouple and clean or replace whatever is causing it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues and none of them mean the unit needs to be replaced. A contractor can flush the exchanger, replace a failed part, or clear a blockage and get it running again.
