Elk River winters push your water heater hard
Cold nights here average 8°F from December through February, and that means the water coming into your tank is colder too. The burner or heating element has to work longer to bring it up to temperature, and it does this for nine months of the year, September through May. That extra runtime wears on the thermocouple and the heating element sooner than it would somewhere milder.
Minnesota also sees its share of power interruptions, with 13% of households losing power for at least a day in 2024, and Sherburne County has logged 23 winter storms and 27 damaging wind events over the past ten years. If your water heater runs on electricity, an outage means no hot water until power is back. If it has a standing pilot, it will relight on its own, but an electronic ignition system needs a working outlet to start back up.

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?
- The most common cause is the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over years and eats away at the lining, and once the steel underneath starts to corrode, water finds its way out. It can also be a loose drain valve or a fitting that has failed, which a contractor can check in a few minutes. If the tank itself is the source, the water heater needs to be replaced, since a rusted tank cannot be patched or sealed.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer telling the gas valve the pilot is lit, so the valve shuts the gas off. A weak or dirty pilot flame can cause the same problem, and so can a draft in the area around the water heater pulling the flame away from the thermocouple. A contractor can test the thermocouple and replace it if it is reading low. Do not keep relighting the pilot over and over if it will not hold. That points to a part that needs replacing, not a fluke.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues include a clogged inlet filter, a buildup of scale on the heat exchanger, a failed igniter, or an error code from a sensor, and a contractor can diagnose which one you have and replace the part. Tankless units also have more electronics than a tank model, so the exact repair depends on what the diagnostic code points to. A contractor will need to look at the unit itself to say what it needs.
