What a water heater in Lincoln has to handle
Winter nights here average 18°F from December through February, and homes call for heat eight months a year, October through May. A new water heater works through that whole stretch, alongside the furnace, and it needs to keep up with cold incoming water on the coldest nights of the year, not just the mild ones.
Power doesn't always stay on. A quarter of Nebraska households lost power for 24 hours or more in 2024, and the county has seen 19 winter storms and 151 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on an igniter will not light until the power comes back, though most start up again on their own once it does. Whatever gets installed also has to meet the federal minimum efficiency for its size, which is set separately for each tank volume rather than as one number for every water heater.

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?
- Look at the age first. Once a tank water heater is old enough that it's near the end of its expected life, a repair is just delaying the same decision. Rust-colored water from the hot tap, a tank that's damp or rusting at the seams, or water pooling underneath are signs the tank itself is failing, not something a part swap fixes. If it's making rumbling or popping noises, sediment has built up on the bottom, and that shortens what life the tank has left. A contractor can tell you whether what you're seeing is a fixable problem or the tank giving out.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. Tankless units heat water on demand instead of storing it, so you don't run out of hot water partway through back-to-back showers or a full load of laundry. They also take up less space since there's no tank sitting in a closet or basement. The tradeoff is that a switch usually means changes to the gas line, venting, or electrical to match what the new unit needs, so a contractor has to look at your setup before you'll know what's involved.
- What changes when you install a tankless water heater?
- The unit itself is smaller, mounted on a wall, and heats water as it flows through rather than storing a tankful. That usually means the gas line has to be sized for the higher burner demand tankless units run at, and the venting is different from what a tank uses, since a tankless unit vents differently and often needs a dedicated line run to the outside. Some homes also need an upgraded electrical connection for the unit's ignition and controls. None of this is a sign anything was wrong with your old setup. It's just what a tankless unit requires to run the way it's built to. A contractor will need to see your gas line, venting, and electrical panel to know exactly what changes your home needs.
