Eight months of heat means a water heater that can't take a break
Water heaters in Eaton County work October through May, 8 months a year, on top of the hot water you use all year. Winter nights averaging 19°F mean the incoming water is colder too, so the tank works harder to bring it up to temperature.
Power is part of the picture. In Michigan, 34% of households lost power for 24 hours or more in 2024, and the county has logged 11 winter storms and 11 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electric ignition will not light until power is back. If you're installing new, a storage tank has to meet a federal minimum efficiency, and that minimum is set by the tank's size and how the household draws hot water, so the right number depends on the unit going in.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Most tank water heaters last around a decade, and once you're past that, a repair is often just delaying a bigger failure. Rust-colored water, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, and that can't be repaired. If the unit is still fairly new and the problem is something like a heating element or thermostat, a contractor can usually fix that instead of replacing the whole thing.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current one is failing. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through a shower. It also takes up less space and tends to last longer than a tank. The tradeoff is that installation usually means changes to the gas line, venting, or electrical, since tankless units draw more power in the moment than a tank does. A contractor can look at your home and tell you what that would involve.
- What changes when you install a tankless water heater?
- The biggest change is usually the gas line. Tankless units need more gas flow in the moment than a tank does, so the existing line often has to be resized to keep up. Venting changes too, since tankless heaters vent differently than a tank and the existing vent usually can't be reused as is. Some models also need a dedicated electrical circuit for their controls. None of this means you can't make the switch, it just means the installation involves more than swapping one unit for another, and a contractor will need to see the house to know exactly what's needed.
