What a Niles winter asks of a water heater
Your water heater works eight months a year here, October through May, with winter nights averaging 21°F. Cold groundwater coming into the tank means it has to work harder to get to temperature, and it does that work most of the year, not just a few weeks of it.
Michigan sees real storms. Berrien County has logged 12 winter storms and 81 damaging wind events over the past ten years, and statewide, over a third of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. An electric one, or a gas unit with electronic ignition, comes back on by itself once power returns. Either way, a new installation is a chance to pick the setup that matches how your home handles a long outage, not just how it runs on a normal day.
Federal efficiency minimums for storage water heaters are set by tank size and by how the household draws hot water, so the minimum for your new unit depends on its rated volume, not on some flat number that applies to all of them.

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?
- Age is the first thing to check. Most tank water heaters last 8 to 12 years, and once you're past that, a repair is a bet against a tank that could fail anyway. Rust-colored water, a tank that's rusting on the outside, water pooling underneath, or a unit that can't keep up with hot water like it used to are all signs to stop repairing and start planning a replacement. If your water heater is out during a winter power outage, keep in mind most gas models with a standing pilot don't need power to run, but electric units and gas units with electronic ignition won't come back on until power does.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on what's wrong with your current tank. A tankless unit heats water on demand instead of storing it, so you don't run out of hot water partway through a shower, and it takes up much less space than a tank. The tradeoff is that installation is more involved than swapping one tank for another, since venting and sometimes gas line or electrical work have to match the new unit. A contractor can look at your home and tell you what switching would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made as you use it instead of pulled from a tank that's kept hot all the time. That means no standby heat loss, but it also means the unit needs enough gas supply or electrical capacity to heat water fast enough for what you're running at once. Venting is different too, since tankless units vent differently than a tank does, so the flue or vent pipe often has to change along with it. Because of that, this isn't usually a straight swap, and a contractor will need to check your gas line, electrical, and venting before installing one.
