Eight months of demand, and a grid that doesn't always hold
Water heaters in Jackson County work eight months a year, October through May, with winter nights averaging 19°F. That is a long stretch for a tank to carry a household's hot water without a break.
Power doesn't always stay on through it. Michigan households went at least 24 hours without power at a rate of 34% in 2024, and the county has logged 13 winter storms and 31 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on an electric igniter, or is fully electric, will not until power is back.
Whatever gets installed also has to meet the federal minimum efficiency set for its size. That minimum is set separately for each draw pattern and tank volume, so two tanks of different size are held to different numbers even when they're the same type of heater.

A heat pump water heater would save about $410 a year to run in Michigan compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Most tank water heaters last eight to ten years, and once you're past that, a failure means water on the floor, not just a repair call. Other signs to watch for are water that's rusty or has a metallic smell, popping or rumbling sounds from sediment in the tank, and water pooling around the base. If your unit is older and you're already dealing with lukewarm water or you're calling for repairs more than once a year, replacing it before it fails is the safer bet.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower, and it takes up much less space than a tank. But installing one often means changes to the gas line, venting, or electrical to match what the unit needs, and not every home is set up for that without extra work. A contractor can look at your existing setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets heated as you use it instead of sitting ready in a tank. That means the unit needs enough gas supply, or in some cases a bigger electrical circuit, to heat water fast enough for your fixtures. Venting is different too, since tankless units use a different type of vent than a standard tank. Where the tank used to give you a fixed amount of hot water before it ran out, a properly sized tankless unit keeps up as long as you're running water, though very high demand from multiple fixtures at once can still stretch it.
