Eight months of the year, your water heater is working against cold ground water
From October through May, the water coming into your house is cold, and your water heater has to work harder to bring it up to temperature. Winter nights averaging 22°F make that job longer during exactly the months you need hot water most.
Power matters too. Storms come through this area, 13 winter storms and 68 damaging wind events over the last ten years, and statewide, 17% of households lost power for 24 hours or more in 2024. If you're choosing a new water heater, that history is worth weighing. A gas unit with a standing pilot will light again on its own when the power comes back. An electric one needs the power itself to make hot water at all.
Whatever you install has to meet the federal minimum efficiency for storage water heaters, which is set by tank size and how the household draws hot water, not one number for every unit. A contractor can size that to your household and tell you what it means for the tank you're replacing.

- 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 measured in years, not decades, and once yours is old, a repair just delays the same problem. Look for rust colored water from the hot tap, a tank that's rusting on the outside, or water pooling underneath, since that means the tank itself is failing and no part can fix that. If it's making rumbling or popping noises, sediment has built up on the bottom and the tank is working harder than it should. A unit that can't keep up, running out of hot water faster than it used to, is also telling you it's near the end.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just your current tank's condition. A tankless unit heats water only when you open a hot tap, so it doesn't hold a reserve that runs out mid shower, and it takes up much less space since there's no tank. It also tends to last longer than a storage tank. The tradeoff is that it needs different venting and often different gas or electric supply than what's already run to your old heater's spot, so a contractor needs to look at your setup before you can know if the switch makes sense for your house.
- What changes when you install a tankless water heater?
- The unit itself is smaller, usually mounted on a wall instead of sitting on the floor, so where it goes in your house can change. It needs its own venting, sized and routed for that unit, which is different from what a tank uses. Gas fired tankless units often need a larger gas line than the one feeding your old tank, because they draw more heat in the moment water is running rather than spreading it out over the day. Electric tankless units can need a bigger electrical circuit for the same reason. A contractor will check your gas line, venting path, and electrical panel against what the new unit needs before installing it.
