Vermillion asks a lot of a water heater
Winter nights here average 13°F, and homes need heat running October through May, eight months of the year. A water heater put in this winter is expected to hold up through a long cold stretch before it sees a break.
Federal efficiency minimums for storage water heaters aren't one number. They're set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes answer to different minimums even when they're the same type. Whoever installs yours should know which minimum applies to the size you're getting.

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?
- Age is the first thing to check. Most tank water heaters last around a decade, and once you're past that, a repair is often just delaying the same failure. Look for rust-colored water, a tank that's rusting on the outside, or water pooling underneath it. That last one usually means the tank itself is failing, not a part inside it, and once the tank goes there's no repairing it. If your water heater sits in an unheated garage or basement here, a failure in the middle of winter is a real problem, so it's worth replacing an old unit before it quits rather than after.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether tank heaters are wrong for this area. A tankless unit heats water as it flows through, so you don't run out partway through a shower, and it takes up less space than a tank. What it won't do is deliver more gallons per minute than it's rated for, so if several people run hot water at once in your house, sizing matters more than the tankless label itself. A contractor can look at your household's hot water use and tell you whether tankless makes sense for it.
- What changes when you install a tankless water heater?
- The biggest change is what the installer has to run to the unit. A tankless heater needs enough gas line capacity, or enough electrical capacity if it's electric, to heat water on demand, which is a bigger draw at any one moment than a tank heater's burner or element. Venting is different too, often a different diameter or material than what a tank heater used. Because there's no tank holding a reserve, the unit also needs a steady water supply and correct sizing for your home's fixtures. All of this is why a straight swap from tank to tankless usually involves more than disconnecting one unit and connecting another.
