Cold groundwater and winter outages both take a toll
Your water heater works harder here because the water coming into it starts out cold. Winter nights average 14°F from December through February, and the ground and pipes feeding your unit stay cold for months, from September through May. That means longer recovery times and more strain on the heating element or burner every time you draw hot water.
Power matters too. Across Wisconsin, 18% of households lost power for at least 24 hours in 2024, and Brown County has seen 22 winter storms and 78 damaging wind events over the past ten years. A gas water heater with electronic ignition will not relight on its own once power drops, and you will notice cold water at the tap until it is reset.

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 from the inside, and once that happens the tank can't be patched or sealed. It could also be the drain valve or a fitting that's loose or worn, which a contractor can replace without touching the tank. The only way to tell the difference is to have someone look at where the water is actually coming from. If it is the tank, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- A weak or failing thermocouple is the most common reason. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep sending gas. When it wears out, it stops sensing the flame properly and shuts the gas off, even though the pilot lit fine a moment ago. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be fixed without replacing the whole unit. Common issues are a clogged inlet filter, mineral buildup on the heat exchanger, or a sensor that's failing, all of which a contractor can service or replace on their own. The unit's error code usually points to which part is causing the trouble. A contractor can read that code and tell you whether it's a repair or something bigger.
