What Vergennes winters ask of a water heater
December through February, nights here average 12°F. A water heater in an unheated basement or garage works harder to bring cold groundwater up to temperature, and it does that work nine months of the year, September through May, whenever the rest of the house needs heat too.
Power matters as much as cold does. Statewide, 21 percent of Vermont households lost power for at least 24 hours in 2024, and Addison County has logged 55 winter storms and 94 damaging wind events over the past ten years. A storage tank with a standing pilot will keep making hot water through an outage. One that depends on an igniter or a control board will not fire again until the power is back. Either way, the new unit has to meet the federal minimum efficiency for its type and size, a standard that's set separately for each tank volume and draw pattern rather than one number for every heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Most tank water heaters have a working life span, and once one gets old enough, a repair is just delaying the replacement it already needs. Rusty water, a tank that's damp or rusted around the base, or water that won't stay hot are all signs the tank itself is failing rather than one fixable part. If you're seeing any of these, it's worth replacing the tank before it fails on its own schedule instead of yours.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether tank heaters are bad. A tankless unit heats water as you use it instead of storing it, so you get a steady supply and never run out mid-shower the way you can with a tank. It also takes up less space than a tank does. Whether it's the right call for your house comes down to your gas line, venting and hot water use, and a contractor can walk through those specifics with you.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand. That usually means new venting, since tankless units vent differently than a tank does, and it can mean upgrading the gas line if the unit needs more gas flow than your old tank did to heat water that fast. The unit itself mounts on a wall instead of standing on the floor, which frees up space where the tank used to sit. A contractor can look at your gas line, venting and where you want it mounted before pricing the job.
