What a Rutland County winter asks of a new water heater
Homes here need heat from September through May, nine months of the year, and a water heater is working through all of it. Winter nights average 12°F from December through February, and the colder your household water runs, the more a tank has to do to bring it up to temperature.
Storms are part of the picture too. Rutland County has seen 66 winter storms and 104 damaging wind events over the last ten years, and statewide, 21% of households went at least a day without power in 2024. A gas water heater with a standing pilot keeps working through an outage. An electric one will not heat water until power is back.
Federal efficiency minimums for storage water heaters are not one number. The minimum is set by a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes can face different minimums even within the same type. A contractor sizing a new unit for your household will account for this.

- How do I know it's time to replace my water heater?
- Age is the first thing to check against the tank's rated life, and a contractor can tell you where yours stands from the model number on the tag. Watch for water that takes longer to heat, rusty or metallic-tasting water, or moisture pooling around the base of the tank. Rust in the water usually means the tank itself is corroding from the inside, and that's not something a repair fixes. If you're seeing any of these signs on an older unit, replacement is the safer call.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on whether tankless is better in some general sense. A tankless unit heats water only when you're using it, so it doesn't hold a reserve of hot water the way a tank does. With 21% of Vermont households losing power for 24 hours or more last year, that difference matters here. A storage tank keeps whatever hot water is already inside it even when the power drops, and a tankless system won't. If your priority is not running out of hot water during a long shower or back-to-back loads of laundry, tankless solves that. If your priority is having some hot water on hand during an outage, a tank does that better.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space with a tank. It needs a gas line sized for its higher burner output, or a dedicated electrical circuit if it's electric, and venting rated for the unit rather than a standard water heater vent. A contractor will check your home's existing gas line and electrical panel to confirm they can support it before install, since that's specific to each house. Once it's in, water heats on demand as it flows through the unit instead of sitting in a tank waiting to be used.
