Long winters and outages put extra strain on your water heater here
Water heaters here work against cold incoming groundwater from September through May, nine months of the year. The colder that water is, the longer the burner or heating element has to run to bring it up to temperature, and that extra runtime wears on igniters, thermocouples, and heating elements sooner than it would in a milder place.
Winter here also brings the risk of losing power. In Wisconsin, 18% of households went at least 24 hours without power in 2024, and Outagamie County has seen 22 winter storms and 79 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition will not light again until power is back. If your water heater is struggling to keep up or will not fire at all, it is worth having someone look at it before the next cold snap.

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 once that happens the tank needs to be replaced, not patched. The leak can also come from a drain valve that isn't sealed tight, or from a fitting where a pipe connects into the top of the tank, with water running down the outside to pool at the bottom. A licensed contractor can tell you in a few minutes which one it is, but if the tank is rusted through, that water heater is done.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small part 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 sense the flame properly, so the valve shuts the gas off and the pilot goes out. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it from lighting fully. A standing pilot doesn't use electricity, so a power outage isn't the cause here.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. A failed igniter, a clogged inlet filter, a buildup of scale on the heat exchanger, or a sensor error are all things a licensed contractor can diagnose and fix without replacing the unit. Bring up any error code shown on the display, since that's usually what points to which part is causing the trouble.
