Vergennes winters push your water heater hard
Groundwater coming into your house is already cold before winter even starts, and from December through February, nights here average 12°F. Your water heater has to work harder to make up that difference, and it runs that way from September through May, nine months of the year. The heating element or burner cycles more, and the parts that make it fire keep wearing down.
Power loss adds another problem. Across Vermont, 21 percent of households lost power for 24 hours or more in 2024, and Addison County has seen 55 winter storms and 94 damaging wind events over the past ten years. Most water heaters come back on by themselves once power returns, but if yours doesn't relight or the pilot won't catch, that is worth a look before you need hot water and don't have it.

- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself corroding from the inside and starting to fail. Sediment builds up on the bottom of the tank over years and traps moisture against the metal, which wears through the lining. Water pooling underneath can also come from a loose drain valve or a fitting that has worked itself loose, so it is worth checking those before assuming the tank is done. Once the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer hold the gas valve open. The thermocouple is the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. When it wears out or sits out of position, the valve shuts the gas off as a safety measure, even though you just relit it. A weak pilot flame, a draft blowing on it, or a clogged pilot orifice can cause the same symptom, so a contractor will check all of those before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is usually cleared with a descaling flush rather than a replacement. Igniters, flow sensors, and venting issues can also be repaired on their own. A full replacement is usually only needed when the heat exchanger itself has failed.
