Nine months of hard use, and cold water to start
Aberdeen homes need heat from September through May, nine months of the year. That same stretch is when a water heater works hardest, because the water coming into the tank starts out cold and winter nights here average 6°F.
Federal rules set a minimum efficiency for storage water heaters, but the number is not the same for every tank. It runs on a formula based on the tank's rated volume, applied separately across four different draw patterns, so two tanks of different sizes can carry different minimums. Whoever installs your water heater needs to know which figure applies to the size going into your home.
- 6°F
- the average winter night, and colder incoming water means longer heating
- 9 months
- September through May, the months homes here need heat

A heat pump water heater would save about $300 a year to run in South Dakota compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water pooling around the base of the tank. That means the tank itself has failed and there's no fixing it, only replacing it. Rusty water from the hot tap, a tank that's making rumbling or popping noises, or water that won't get hot anymore are also signs the unit is on its way out. If you're seeing any of these, have a contractor look at it before it fails outright. A tank that fails suddenly here means a cold snap with no hot water on top of the cleanup, so catching it early matters.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out partway through a shower and it doesn't sit there heating water you're not using. Switching usually means changes to the gas line, venting, or electrical supply, since a tankless unit draws more power in short bursts than a tank does. A contractor can tell you what your house would need and whether it fits how your household uses hot water.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, which is the most visible change. Behind that, the installation often calls for a larger gas line, different venting, or upgraded electrical, because the unit has to deliver a burst of heat the moment you turn on a tap rather than drawing from stored hot water. A contractor will need to check the gas line, venting, and electrical setup in your house before installation to know what has to change.
