A new water heater here works through eight cold months a year
Grand Island homes need heat from October through May. A water heater carries part of that load the whole time, and on winter nights that average 17°F it has more work to do to bring water up to temperature.
Power does not always stay on. Nebraska households went without power for 24 hours or more at a real rate last year, and Hall County has seen 22 winter storms and 117 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. An electric one, or a gas unit with an electronic igniter, comes back on by itself once power returns. A new installation should account for both.

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?
- Watch for water around the base of the tank. That usually means the tank itself has started to fail from the inside, and once that happens it does not get better. Rusty or metallic-tasting hot water, a pilot light that keeps going out, or a unit that just seems old are other signs worth taking seriously. If the heater struggles to keep up on the coldest nights, that is worth noting too, since incoming water runs a lot colder when it is 17°F outside.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on the fact that your current tank is getting old. A tankless unit heats water on demand, so you are not paying to keep a tank of water hot all day, and you do not run out of hot water partway through a shower. But it is a different kind of installation than swapping one tank for another, often needing different gas or electrical service. A contractor can look at your home and tell you what that would take here.
- What changes when you install a tankless water heater?
- The main change is that hot water gets made as you use it instead of being stored ahead of time. That means no tank sitting in a closet or basement, but it also means the unit needs enough gas supply or electrical capacity to heat water fast, which your current setup may not have. Venting requirements are usually different too. These are things a contractor checks before quoting the job, since the right setup depends on the house.
