A new water heater here needs to handle a long cold season and the chance of losing power
Winter nights in Crow Wing County average 5°F from December through February, and homes here need heat nine months of the year, September through May. A water heater works harder in that stretch, since the water coming into the tank starts out colder than it would further south. That means more time spent heating it back up to temperature.
The county sees storms too. Ten years of records show 33 winter storms and 139 damaging wind events, and statewide, 13% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition, and any electric water heater, will not, though most come back on by themselves once power returns. Whatever you install, it has to meet the federal minimum efficiency for its size and type. That minimum is not one number. It is set by a formula tied to the tank's rated volume, and it applies differently depending on how the household draws hot water, so two tanks of the same kind can face different minimums if their sizes differ.

A heat pump water heater would save about $360 a year to run in Minnesota 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 it's behaving. Rust-colored water, a tank rusting at the seams, or water pooling underneath are signs to replace it now rather than wait. Homes here need heat from September through May, so a tank that fails partway through that stretch leaves you without hot water when you need it most. If yours is old and still working, it's worth having a contractor look at it before it fails on its own schedule.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on where you live. A tankless unit heats water only when you're running a tap, so you don't pay to keep a tank hot all day, and you get a steady supply instead of running out after a few showers. It costs more to install and needs gas or electrical service sized for it, so a contractor has to check what your house already has before this makes sense.
- What changes when you install a tankless water heater?
- The unit itself is smaller and usually goes on a wall instead of taking up floor space. It needs its own venting, sized for the unit, and if it runs on gas, the gas line often has to be upsized to feed it. A permit and inspection are required for this kind of install in most cities and counties here, same as replacing any water heater.
