What Otter Tail County winters do to a water heater
Groundwater coming into your house is already cold, and from December through February it has to fight nights that average 4°F before your water heater can do anything with it. That means longer burner cycles and more of them, and every cycle puts wear on the thermocouple and the igniter. When one of those goes, you get a tank that won't stay lit or won't light at all.
Minnesota also sees real power loss. Statewide, 13% of households were without power for a day or more in 2024, and this county has logged 88 winter storms and 157 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not, and it needs to be relit once the power is 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 of the time it means the tank has rusted through from the inside and is failing. Water heaters have a steel tank with a glass lining, and once that lining cracks, the steel underneath rusts and eventually leaks. It can also be a loose drain valve or a failed temperature and pressure relief valve, both of which a contractor can check before condemning the tank. If the leak is coming from the tank itself, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple or flame sensor, the part that tells the gas valve the pilot is burning. When it wears out or gets coated in soot, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft blowing the flame out can also cause it. A standing pilot doesn't use any electricity, so power going out won't affect it, but a bad thermocouple will need to be replaced by a contractor.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. Mineral buildup on the heat exchanger is the most common issue, and flushing the unit often restores it. Igniters, flow sensors, and venting problems can also be replaced or corrected without swapping out the whole unit. A contractor can run the diagnostic codes most units display to find out exactly what's failing.
