Cold groundwater and long winters wear on your water heater here
Your water heater runs harder in Baraboo than it would somewhere milder. Incoming water is cold most of the year, and with heat needed October through May, the tank is recovering more often, for longer stretches, than it would in a warmer county. That extra cycling wears on the heating element or burner assembly and on the thermostat that tells it when to fire.
Winter also brings the power out. Wisconsin saw 18% of households lose power for a full day or more in 2024, and Sauk County has logged 61 damaging wind events and 12 winter storms over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not restart on its own, and you will notice hot water not coming back even after the lights do.

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 failed. Water heaters rust from the inside out, and once a hole opens up in the tank, water works its way down and out the bottom. It can also be a loose drain valve or a fitting that's failed, which is a much simpler fix, so it's worth checking those before assuming the worst. A leaking tank won't stop on its own and needs to be replaced, not patched.
- 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's safe to keep the gas flowing. When it wears out, it can't hold that signal, so the valve shuts the gas off and the pilot goes dark. A dirty pilot orifice or a draft in the area can cause the same problem, but the thermocouple is where a contractor will usually check first. This part can be tested and replaced without replacing the whole unit.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues, and each of those can be cleaned or swapped out on its own. Tankless units also run diagnostic codes when something's wrong, which point a contractor straight to the part at fault. Whether repair makes sense for your unit depends on its age and what's actually failed, which a contractor can tell you once they've looked at it.
