Cold groundwater and long winters wear on your water heater here
Groundwater coming into your house starts out cold, and from December through February your water heater is fighting winter nights that average 8°F. That means longer burner or element run times to get the same hot shower, and more cycles on the parts that make heat. The thermostat, the heating element or the burner assembly, and the anode rod all wear faster when the unit works this hard nine months of the year.
Minnesota also sees real power loss. Statewide, 13% of households went at least 24 hours without power in 2024, and Chisago County has logged 25 winter storms and 29 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 or an electric unit will not come back on until power is restored, and if that happens on a cold night, you will notice the water turn lukewarm fast.

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 and is starting to fail. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath corrodes and eventually leaks. A drain valve that is not fully closed or a loose fitting can also cause water at the bottom, so it is worth checking those first. If the leak is coming from the tank itself, the tank needs to be replaced. It will not seal or patch.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a failing thermocouple. This is the small sensor that tells the gas valve the pilot is burning, and when it wears out or sits out of position, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft blowing on the flame can cause the same problem. A contractor can test the thermocouple and clean or adjust the pilot assembly to find which one it is.
- Can a tankless water heater be repaired?
- Yes. Most problems come down to a failed igniter, a flow sensor, or mineral scale built up on the heat exchanger. A contractor can test each part and replace the one that failed rather than the whole unit. Scale buildup is common where the water is hard, and flushing the system usually clears it and restores heat output.
