Winona winters are hard on a water heater
Groundwater coming into your house is already cold when winter sets in, and with nights averaging 11°F from December through February, your water heater works harder for months to make up the difference. The burner or heating element runs longer and more often to hold the same temperature, and that extra work is what wears out a thermocouple, igniter, or heating element before its time.
Winona County has seen 30 winter storms and 63 damaging wind events over the past ten years, and statewide, 13% of households lost power for 24 hours or more in 2024. 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. If yours runs on electricity alone, it stops heating the moment the power does.

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 this means the tank itself has rusted through and is failing. The bottom of the tank sits in water all day, so sediment and rust build up there faster than anywhere else, and eventually the metal gives out. A loose drain valve or a fitting can also leak and look like the same problem, so it is worth checking those before assuming the worst. If the tank is the source, it needs to be replaced, not patched, since a leaking tank will not seal back up.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. 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 in the room can also blow the flame out. If you have relit it more than once and it keeps going out, that points to the thermocouple or the gas valve rather than something you're doing wrong.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed sensor, and each of these can be cleaned or replaced without swapping the whole unit. Error codes on the display usually point straight to the part at fault. A contractor can read the code and tell you whether it is a repair or something more serious.
