Cold like this is hard on a water heater
Groundwater coming into your house is already cold before winter even starts, and from December through February your nights average 4°F. The tank has to work harder and longer to make up that difference, and the burner or element runs more to hold temperature. That extra run time wears on the thermostat and the heating element or gas valve faster than it would somewhere milder.
Power outages add to it. Across North Dakota, 7% of households lost power for at least 24 hours in 2024, and Williams County has seen 23 winter storms and 84 damaging wind events over the past ten years. When the power drops in weather this cold, a tank that was already working hard just stops, and the water goes cold fast. Most units come back on their own once power returns, but if yours does not, that points to a problem worth having someone look at.

- Why is my water heater leaking from the bottom?
- The tank itself is likely rusted through and holding water is failing at a seam or fitting. Sediment builds up at the bottom of the tank over years and corrodes the steel from the inside, and once it leaks there, the tank is done. A loose drain valve or a fitting can also leak and look the same at first, so a contractor should check those before condemning the tank. If it is the tank itself, repair is not an option, only replacement.
- Why won't the pilot light on my water heater stay lit?
- A weak or dirty thermocouple is the most common reason a pilot won't stay lit. The thermocouple senses the flame and holds the gas valve open, and once it wears out or gets coated in soot it can't read the flame right, so the valve closes and the pilot goes out. A clogged pilot tube or a draft pulling on the flame can cause the same thing. A contractor can test the thermocouple's output and replace it if it's reading low.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Igniters, flow sensors, and heat exchangers can all be replaced without swapping out the whole unit. Error codes on the display usually point a contractor straight to the failed part. Mineral buildup in the heat exchanger is common with hard water and is cleared with a descaling flush rather than a replacement.
