Cold groundwater and long winters wear on your water heater
Your water heater works harder here than in most places. Groundwater coming into the tank is already cold from a winter that runs September through May, so the burner or the elements have to work longer to bring it up to temperature. That extra runtime adds up over the years and it is often the heating element or the burner assembly that gives out first.
Power matters too. Minnesota saw 13% of households lose power for 24 hours or more in 2024, and Goodhue County has had 35 winter storms and 52 damaging wind events over the past ten years. When the power drops, an electric water heater stops heating until it is back, and the tank loses its heat slowly until then. If yours has not come back on after an outage, or the water is taking longer to heat than it used to, that is worth a look.

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 most common reason is that the tank itself has rusted through and is failing. Sediment builds up in the bottom of the tank over the years, and it corrodes the steel from the inside until a crack or hole forms. A leak can also come from a loose drain valve or a fitting that has worked itself loose, which a contractor can check before assuming the tank is done. Once the tank itself is leaking, it needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- This usually means the thermocouple has worn out. That's the small part that sits in the pilot flame and tells the gas valve the pilot is lit. When it fails, the valve shuts the gas off as a safety measure, even though the pilot was burning fine a moment before. A dirty pilot orifice or a draft blowing the flame out can cause the same thing, so a contractor will check both before replacing parts.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a dirty inlet filter, a failed igniter, mineral buildup on the heat exchanger, or a fault code caused by a sensor. Because these units are more complex than a tank, a contractor needs to read the fault code or test the parts to know which one it is.
