Otsego winters put water heaters to work
Homes here need heat nine months of the year, and from December through February nights average 8°F. Cold like that means your water heater is pulling in colder water to start with, so the burner or heating element has to run longer to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in electric units, or the burner assembly in gas ones.
Otsego has seen 26 winter storms and 65 damaging wind events over the past ten years, and storms like that knock out power. Across Minnesota, 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 electric ignition will not fire until power comes back.

A new water heater would cut about $50 a year off hot water for a typical Minnesota home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through from the inside and is starting to fail. Water heaters aren't built to be repaired once the tank leaks, since the steel lining has broken down and no patch holds against that kind of corrosion. Sometimes what looks like a tank leak is actually the drain valve or a loose fitting on the cold water inlet, which a contractor can check before assuming the tank is done. If the water is coming from underneath the tank itself, plan on replacing the unit rather than fixing it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out it can't confirm the flame anymore, so the gas valve shuts off the pilot as a safety measure. A dirty pilot orifice or a draft near the burner can cause the same problem, so it's worth having a contractor look before replacing parts. A thermocouple is a simple fix and one of the more common repairs on older gas water heaters.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit come down to a handful of parts that a contractor can replace, including the igniter, the flow sensor, or the heat exchanger. Mineral buildup from hard water is one of the more frequent issues, and it can be flushed out before it damages other parts. If the unit is throwing an error code, that code usually points straight to what's failing, which makes tankless repairs more direct than guessing at the problem.
