St. Albans winters ask a lot of a water heater
Cold groundwater comes into your house colder here, and your water heater has to bring it up to temperature nine months a year, September through May. On the coldest nights, December through February, that's against an average of 11°F outside. A tank sized for that load holds up. One sized for a milder place falls behind.
Power is part of the picture too. Across Vermont, 21% of households lost power for 24 hours or more in 2024, and Franklin County has seen 51 winter storms and 67 damaging wind events over the past ten years. A gas storage tank with a standing pilot keeps heating water through an outage. An electric one won't, though it comes back on by itself once power returns.
Whatever you choose, the new unit has to meet the federal minimum efficiency for its category, and that minimum isn't one number. It's a formula based on the tank's rated volume, applied differently across draw patterns, so two tanks of different sizes can face different minimums even within the same type. A licensed installer will know which one applies to the tank going into your house.

- How do I know it's time to replace my water heater?
- The clearest sign is age combined with trouble. Once a tank water heater is old and starts acting up, a leak at the tank itself means replace it, not repair it, since a leaking tank cannot be patched. Rusty hot water, a tank that rumbles or takes longer to heat, or water pooling at the base are all signs the tank is failing rather than having a minor problem. If the unit is still fairly new and the issue is something like a bad thermocouple or heating element, a contractor can usually repair that instead of replacing the whole tank.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current heater being broken. A tankless unit heats water only when you run a tap, so you get endless hot water instead of running out partway through a shower, and it takes up far less space since there is no tank. Winters here average 11°F overnight from December through February, and colder incoming water means the unit has to work harder to hit the same output temperature, which a contractor will account for when sizing the unit for your house. If your home already has gas lines and venting sized for a tankless unit, the switch is more straightforward than if that has to be added.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed supply and depletes it, but a tankless unit heats water on demand as long as you're using it. Installation usually calls for different venting than a tank uses, and gas units often need a larger gas line to supply enough fuel for the burner to heat water instantly. Vermont sees enough power interruptions, with 21% of households losing power for at least 24 hours in 2024, that it's worth asking a contractor whether the model you're considering needs electricity to ignite, since some tankless units won't produce hot water at all during an outage even with gas supplied.
