What Itasca County winters do to a water heater
Groundwater coming into your house is already cold, and from September through May your water heater has to work harder against it for nine months straight. On nights that average 1°F, a tank set in a garage or unheated basement loses heat faster, so the burner or heating element cycles on more just to hold temperature. That extra cycling wears on the thermocouple and the heating element, and it shows up as water that used to run hot now running lukewarm, or a recovery time that used to be quick now taking a while.
Power matters too. Minnesota saw 13% of households lose power for 24 hours or more in 2024, and this county has logged 59 winter storms and 108 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage, but one with electronic ignition will not light again until power is back and someone resets it. If your water heater has stayed cold since the last outage, that is usually why.

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?
- The tank itself has likely rusted through and is failing. Sediment builds up in the bottom of the tank over the years, and once it corrodes through the steel, water finds its way out. A loose drain valve or a fitting on the bottom can also leak and is worth checking first since that part can be replaced. But once the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- A weak or dirty thermocouple is the most common reason. That's the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. If it's coated with soot or has drifted out of position, it reads the flame as out and cuts the gas even while the pilot is burning. A draft blowing across the pilot or a failing gas valve can cause the same thing. Since a standing pilot doesn't need power to run, this problem isn't tied to outages, it's the part itself that needs attention.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed flow sensor, or an ignition problem are common and a contractor can usually fix them without replacing the unit. Flushing the system to clear scale is routine maintenance that keeps these problems from starting in the first place. A contractor will need to look at the specific unit to say what's wrong and price the repair.
