What a Monroe County winter asks of your water heater
Your water heater works eight months a year here, October through May, with winter nights averaging 21°F. Cold groundwater takes more energy to bring up to temperature, and the tank does that work stretch after stretch through the whole season.
Power is part of the picture too. In 2024, over a third of Michigan households went at least 24 hours without power at some point, and the county has logged 8 winter storms and 95 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. Most electric units do not until power comes back. New storage water heaters also have to meet a federal efficiency minimum, and that minimum is set by the tank's size and how a household draws hot water through the day, so the right number for your home depends on the unit going in.

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. Once a tank water heater is old enough that it needs a repair, replacing it is often the better move since another part will just fail next. Watch for water pooling around the base, since that usually means the tank itself is rusting through and no part swap fixes that. Rusty water from the hot tap, a tank that's noisy when it heats, or hot water that runs out faster than it used to are all signs the tank is on its way out. If yours is showing more than one of these, replacing it before it fails outright saves you from a cold morning and possible water damage.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on what's wrong with your tank. A tankless unit heats water as you use it instead of storing it, so you don't run out partway through a shower, and it doesn't sit there keeping a tank of water hot all day when nobody's using it. But going tankless usually means changes to the gas line, venting, or electrical to the unit, since these units draw more power in the moment than a standard tank. A contractor can look at your home's setup and tell you what switching would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, but what feeds it usually needs upgrading too. Tankless heaters draw more gas or electricity in a short burst than a tank does, so the gas line, venting, or electrical circuit often needs to be sized up to match. Venting changes too, since tankless units typically vent differently than a standard tank and need their own path to the outside. A contractor should walk through your home's specifics before the swap, not after.
