Nine months of cold ground water takes a toll
Your water heater works harder here than in most places. From September through May it is heating groundwater that starts out cold, and on the nights that average 12°F, it runs longer to hold a set temperature. That extra runtime wears on the heating element and the thermostat that controls it, and it shows up as water that never quite gets hot or runs out faster than it used to.
Power loss is the other part of it. In Vermont, 21% of households went at least 24 hours without power in 2024, and Windsor County has seen 18 winter storms and 70 damaging wind events over the past ten years. Most tanks come back on by themselves once power returns, but a pilot light on an older unit may need to be relit by hand, and a tank that sat cold for a day gives you a cold shower until it catches back up.

- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself has corroded through and is starting to fail. Sediment builds up inside the tank over years, and it wears through the steel from the inside, usually starting at the bottom seam. A leak could also come from a loose drain valve or a fitting nearby, which is worth checking before you assume 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?
- The most likely cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it wears out, it fails to sense the flame properly and shuts the gas off even though the pilot is lit. A draft blowing out the pilot or a dirty pilot orifice can also cause this. A contractor can test the thermocouple in a few minutes and replace it if that's the problem.
- 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 cleared with a descaling flush. Igniters, flow sensors, and exhaust vents can also fail on their own and be replaced without needing a new unit. A contractor can run the error code the unit is showing to find out which part is causing the problem.
