Groundwater this cold makes a water heater work harder here
Groundwater coming into your house has already lost most of its heat by the time it reaches the tank, because St. Cloud winters push nights down to 6°F on average from December through February. Your water heater has to make up that difference every time you run a tap, so the burner or the element stays on longer and cycles more than it would somewhere warmer. That wear shows up first in the thermostat or the heating element on an electric tank, or the burner assembly and thermocouple on a gas one.
Stearns County has seen 30 winter storms and 86 damaging wind events over the past ten years, and statewide, 13% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps working through an outage like that. One with electronic ignition will not relight on its own once the power comes back, and you will notice cold water until it is reset or looked at.

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. Sediment builds up at the bottom of the tank over years, and once it wears a hole in the steel, water finds its way out. A leak can also come from a loose drain valve or a fitting where a pipe connects, and those are worth checking before you assume the tank is done. If the water is actually coming from inside the tank, there is no repair for that. It needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep supplying gas. When it wears out, it stops sensing the flame correctly and shuts the gas off, even though the pilot lit fine a moment ago. A dirty pilot orifice or a draft pulling the flame away can cause the same thing. A contractor can test the thermocouple and replace it, which is a straightforward fix on most standing pilot units.
- 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 igniter, a clogged inlet filter, and error codes from the flow sensor are all things a contractor can diagnose and fix. Regular flushing keeps mineral buildup from becoming the reason it needs service. Only when the heat exchanger itself has failed does replacement usually make more sense than repair.
