Nine months of cold weather to plan around
Sheboygan County homes need heat from September through May, nine months of the year. A new water heater goes in for that same stretch of cold, with winter nights averaging 15°F from December through February.
Power loss is also worth planning for. In Wisconsin, 18% of households went at least 24 hours without power in 2024, and the county has recorded 19 winter storms and 46 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps running through an outage. One with electronic ignition will not light again until the power is back. Whatever you choose, the federal minimum efficiency it has to meet is set by a formula tied to the tank's rated volume, so the number that applies to your install depends on the size you need.

A heat pump water heater would save about $330 a year to run in Wisconsin compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that comes out lukewarm or runs out fast, especially if that is new. Rust colored water from the hot tap, a tank that is rusting on the outside, or water pooling underneath are signs the tank itself is failing, not just a part inside it. A popping or rumbling sound during heating usually means sediment has built up on the bottom of the tank, and that gets worse over time, not better. Most storage tanks last a set number of years before the tank itself starts to go, so if yours is old and showing any of these signs, a contractor can tell you whether it is worth repairing or time to replace it.
- Should I switch to a tankless water heater?
- That depends on what you want from it, not just on your current tank. A tankless unit heats water as it flows through rather than storing it, so you do not run out of hot water partway through a shower, but it also means the flow rate matters more than it did before. Winters here get cold, with nights averaging 15°F from December through February, and incoming water that cold makes the unit work harder to bring it up to temperature. A contractor can look at your home's layout and your household's hot water use and tell you whether tankless makes sense for your situation.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, which means no tank to run out and no standby heat loss while it sits unused. Tankless units are also smaller and mount on a wall, so they free up floor space compared to a storage tank. Venting and gas line requirements are often different from what a storage tank needs, so the installation itself is not a straight swap. A contractor can walk through what your home would need to make the switch.
