Cass County puts a new water heater to work most of the year
Homes here need heat from October through May, eight months a year, and the water coming into the tank is cold for most of that stretch. Winter nights average 18°F from December through February, so the tank is working hardest right when the days are shortest.
Power doesn't always stay on through it. A quarter of Nebraska households went at least a day without power in 2024, and the county has seen 16 winter storms and 63 damaging wind events over the past ten years. Most tank water heaters come back on by themselves once power returns, and a standing pilot model never needed power to begin with. A new installation should account for outages, not just cold water.
The federal minimum efficiency for a storage water heater isn't one number. It's a formula based on the tank's rated volume, applied separately to four different draw patterns, so two tanks of different sizes can face different minimums even if they're the same type.

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, along with how it's failing. Watch for water that takes longer to heat, rust-colored water, a tank that's rusting on the outside, or water pooling underneath it. If the tank itself is leaking, that's the tank failing, not a part you can replace, and it means the heater needs to come out. A contractor can tell you where your specific unit stands once they look at it.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water, not just on replacing what broke. A tankless unit heats water as you use it instead of storing a tankful, so you don't run out during a long shower and it takes up less space on the wall. It also needs the right gas line or electrical circuit for the unit, so a contractor has to check what your home can support before you decide.
- What changes when you install a tankless water heater?
- You get hot water on demand instead of a limited supply that runs out. There's no tank sitting full of water all day, so it takes less floor or wall space and there's no tank to eventually rust through and leak. The gas line, vent, or electrical circuit feeding it often needs to be sized for the new unit, since a tankless heater draws more at once than a tank does. That sizing check is part of what a contractor does before installing one.
