Eight months of cold water demand in Saginaw County
Water heaters here work from October through May, eight months a year, on top of daily use the rest of the summer. Winter nights averaging 19°F mean the incoming water is colder too, so the unit works harder to bring it up to temperature.
Power loss is a real factor here. More than a third of Michigan households lost power for 24 hours or more in 2024, and the county has seen 13 winter storms and 79 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition needs power to light, and most electric and gas units with electronic controls come back on by themselves once power returns. Any new installation has to meet the federal minimum efficiency for its size and type, since the standard is set by tank volume and draw pattern rather than one number for every heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Once a tank has been in service long enough, a failure can happen without warning, so age alone is worth asking a contractor about. Rust-colored water, a tank rusting on the outside, or water pooling underneath means it's already failing. If it's making rumbling or popping sounds, sediment has built up on the bottom of the tank, and that's a heater working harder than it should. A contractor can tell you whether it's worth repairing or whether replacement makes more sense given its age and condition.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your water heater being old or broken. A tankless unit heats water on demand instead of storing it, so you don't run out of hot water partway through back-to-back showers. It also takes up less space than a tank. It's a bigger change than swapping one tank for another, since venting and gas or electric supply needs often have to change too, so a contractor should look at your home before you decide.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made the moment you turn on the tap instead of being stored ahead of time. That means no tank taking up floor space, but it also means the venting is different, since a tankless unit vents differently than a tank does. Gas units often need a larger gas line to supply enough fuel for on-demand heating. A contractor will need to check your home's gas or electric supply and venting before installing one, since what your old tank used may not be enough for a tankless unit.
