Allegan homes need a water heater built for a long, cold season
Winter nights here average 20°F from December through February, and homes run their heat from October through May. That's eight months of cold water coming into the tank instead of water that's already warmed up some. A water heater here works harder to bring that water up to temperature, and it does that work most of the year.
Michigan sees its share of power loss. In 2024, 34 percent of households in the state went at least 24 hours without power at some point, and Allegan County has had 17 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 with electric ignition won't light until the power is back, but it will come back on by itself once it is. Either way, that's worth knowing before you pick a replacement.
New storage water heaters also have to meet a federal efficiency minimum, and that minimum isn't one number. It's set by a formula based on the tank's size, and it's applied differently depending on how the household draws hot water. Two tanks of the same type in different sizes can have different minimums to meet. A licensed installer will know what your size and setup requires.

- How do I know it's time to replace my water heater?
- If your water heater is old enough that you're wondering, that's worth paying attention to. Watch for water that takes longer to heat, rust-colored water, or rust around the tank's fittings. A tank that's rusting from inside can fail without warning, and once it starts leaking there's no repair for that. A licensed contractor can look at the age and condition of your unit and tell you whether a repair still makes sense or whether it's time to replace it.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on your old tank failing. A tankless unit heats water on demand instead of storing it, so you get an endless supply as long as the flow rate doesn't exceed what the unit can heat. It won't run out of hot water partway through back-to-back showers, but sizing one right depends on your actual water demand, not just the size of the tank you're replacing. If your home's power goes out often, know that gas tankless units still need electricity to run their ignition, so they won't work in an outage either.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That usually means different venting, since tankless units vent differently than a tank, and it can mean upgrading the gas line or electrical circuit feeding it, since the unit draws more power in short bursts than a tank does. Space changes too. A tankless unit mounts on a wall and takes up a fraction of the floor space a tank needs. A licensed contractor can walk your house and tell you what that involves for your setup specifically.
