Nine months of heat, and storms that cut power
Faribault homes need hot water for the same nine months they need heat, September through May. Winter nights here average 10°F, and a water heater in an unheated space is working against that cold every time it recovers.
Rice County has logged 34 winter storms and 36 damaging wind events over the past ten years, and 13% of Minnesota households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electricity to ignite will not, until the power comes back. Whatever the type, a new installation has to meet a federal efficiency minimum, and that minimum is set by a formula tied to the tank's rated volume, so a larger tank and a smaller one are not held to the same number.

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?
- Water pooling at the base of the tank means it is time, since that is usually the tank itself failing rather than a fitting. Rusty hot water, a tank that is old, or water that never gets fully hot anymore are the other signs worth acting on. A tank that is rusting from the inside will not get better, and once it starts leaking you are looking at water damage on top of the replacement. If your water heater is getting old, it is worth having a contractor look at it before it fails rather than after.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on cost. A tankless unit heats water only when you turn on a tap, so it will not run out of hot water during a long shower, and it takes up much less space than a tank. Against that, a tankless unit needs a strong incoming gas or electric supply, and if the power goes out it stops working, same as most tank heaters do. A contractor can look at your gas line, electrical panel, and how your household uses hot water and tell you whether the switch makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank heater gives you whatever is stored up, then makes you wait while it recovers, but a tankless unit heats water on demand as long as it is running. That means the gas line or electrical circuit feeding it usually needs to be sized for the unit's higher draw, which is why swapping in a tankless model is not always a straight swap for the space a tank used to sit in. It also means venting changes, since tankless units vent differently than most tank water heaters. A contractor can tell you what your home's gas line, electrical panel, and venting would need.
