What a Dawson County winter asks of a water heater
Winter nights here average 16°F from December through February, and homes run heat October through May, eight months of the year. That is most of the year for a water heater to be drawing in a cold house.
Power is worth planning around too. Dawson County has seen 17 winter storms and 121 damaging wind events over the past ten years, and a quarter of Nebraska households went at least a day without power in 2024. On the efficiency side, the federal minimum for storage water heaters is not one number. It is set by a formula tied to the tank's rated volume, applied across four draw patterns, so the minimum your new unit has to meet depends on its size and how much hot water your household uses.

A heat pump water heater would save about $200 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 the tank is behaving. Look for rust-colored water, a tank that's damp or wet around the base, or water that takes longer to heat than it used to. If the tank itself is leaking, that's not a repair, that's a sign the tank has failed from the inside. A contractor can tell you the age from the serial number if you don't have it written down, and that age is the starting point for deciding whether to repair or replace.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your current heater's age. A tankless unit heats water as it flows through rather than storing a tankful, so you don't run out partway through back-to-back showers or a full load of laundry. It also has no tank to rust out or leak, since there's no standing water sitting in it between uses. What it takes to install one in your home, including the gas line, venting, and electrical, is worth having a contractor look at before you decide, since that part varies house to house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed amount and once it's used up you wait for it to reheat, but a tankless unit heats water as you draw it, so a long shower doesn't compete with the dishwasher for what's left in the tank. The venting is different too, since a tankless unit typically needs its own dedicated vent rather than sharing a flue. Gas line sizing can change as well, since these units draw more gas at once than a standard tank does. A contractor can walk you through what your home's setup will need.
