Blaine winters push your water heater harder
Groundwater coming into your house is already cold when it arrives. From December through February, with nights averaging 9°F, it comes in colder still. Your water heater has to work harder to bring it up to temperature, and it does that work nine months a year, September through May. A gas burner cycles more to keep up. An electric element stays on longer each time.
Anoka County has seen 28 winter storms and 40 damaging wind events over the past ten years. Statewide, 13% of households lost power for at least 24 hours in 2024. A water heater with a standing pilot keeps making hot water through an outage like that. One with electric ignition or an electric heating element does not. It needs the power back before it heats water again.

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, and that means replacement rather than repair. Sediment builds up at the bottom of the tank over years, and it wears through the lining from the inside. A leak can also come from a loose drain valve or a fitting where a pipe connects, and those can be repaired. A contractor can tell you which one you have by looking at where the water is actually coming from.
- 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 the flame is lit. When it wears out, it fails to signal that, and the gas valve shuts the pilot off as a safety measure. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it from reading right. A contractor can test the thermocouple and replace it if it's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is common and is cleared by flushing the system, especially important if the house has hard water. Igniter failures, sensor errors, and venting issues are also things a contractor can diagnose and fix without replacing the unit. Replacement usually only comes up when the heat exchanger itself has failed.
