Sarpy County winters put real demand on a water heater
Winter nights here average 17°F from December through February, and homes run their heat from October through May. Cold groundwater coming into the tank means a water heater works harder to bring it up to temperature, for eight months of the year.
Power doesn't always stay on to run it. A quarter of Nebraska households lost power for 24 hours or more in 2024, and Sarpy County has seen 19 winter storms and 64 damaging wind events over the past ten years. That's worth thinking about when you choose between a tank and a tankless unit, and between gas and electric. Any new water heater installed also has to meet the federal minimum efficiency for its size and type, since the standard is set separately for each tank volume.

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. Most tank water heaters have a working life of about a decade, and once you're near that mark, a repair is often just a delay before the next failure. Watch for water pooling around the base, that usually means the tank itself is rusting through from the inside, and no repair fixes that. Rusty or metallic-smelling hot water is another sign, especially if it happens right at the tap and not from your pipes. If your heater is making popping or rumbling sounds, sediment has built up on the bottom of the tank and is starting to affect how it heats. Bellevue winters bring cold groundwater into the tank for eight months of the year, which means the heater works harder here than it would somewhere warmer, so an aging unit tends to show its age sooner.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water on demand instead of storing and reheating a tank full of it, so you get a steady supply of hot water as long as the fixture is running, rather than running out after a shower or two. It also has no tank sitting full of water to corrode, which is usually what ends a storage heater's life. What it won't do is fix low water pressure or flow problems in your pipes, since those come from the plumbing, not the heater. A contractor can tell you whether your gas line and venting can support a tankless unit, since that changes what installation actually involves.
- 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 means no standby heat loss from a tank sitting full of hot water all day, and no waiting for a tank to recover after a big draw. Tankless units are also much smaller than a storage tank, usually mounted on a wall, which frees up floor space in a utility closet or garage. On the installation side, gas tankless units often need a larger gas line than a storage heater did, plus dedicated venting rated for the higher temperatures they put out. Electric tankless units need enough electrical capacity to handle the load, which an older panel may not have. A contractor can look at your gas line, venting, and panel to say what your home would need.
