What a Seward County winter asks of a water heater
Winter nights here average 17°F from December through February, and homes need heat from October through May, eight months of the year. That is the same stretch a water heater is working alongside a furnace that runs most days, both drawing on the same power and, often, the same gas line.
Power does not always stay on through that stretch. A quarter of Nebraska households went at least 24 hours without power in 2024, and Seward County has seen 13 winter storms and 38 damaging wind events over the last ten years. A gas water heater with a standing pilot keeps heating through an outage. One with electric ignition will not light again until the power is back.
Federal efficiency minimums for storage water heaters are not one number. They are set by a formula based on the tank's rated volume, applied differently depending on how a household draws hot water, so two tanks of the same type and size can face different minimums.

A heat pump water heater would save about $270 a year to run in Nebraska compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age combined with trouble. Most tank water heaters last about a decade, and once yours is getting up there in years, rust colored water, a tank that's noisy or damp around the base, or water that won't get hot anymore all point to a heater that's done. A leak from the tank itself, not a fitting, means replace it now rather than wait, because a tank doesn't get patched. If your heater is still fairly new and the problem is something like a pilot light or a thermostat, a contractor can often repair it instead.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on your current heater failing. A tankless unit heats water as it flows through, so it doesn't run out the way a tank does when several showers or a load of laundry stack up. It also takes up less space and, because there's no tank sitting full of hot water all day, it can cost less to run. Homes here need heat from October through May, and incoming water is cold for those same months, so a contractor should size the unit for your home's coldest months rather than an average.
- What changes when you install a tankless water heater?
- The biggest change is what's connected to it. A tankless unit needs a gas line sized for its higher burner output, or a dedicated electrical circuit if it's electric, and it needs venting built for its exhaust, which is different from a tank's. Some homes already have the right gas line and vent in place, and some don't, so a contractor has to check both before install. You'll also lose the storage buffer a tank gives you during a power outage. A quarter of Nebraska households went at least 24 hours without power in 2024, and that's worth knowing because most modern tankless units need electricity to ignite and run even though they burn gas, so no power means no hot water either way.
