Fargo winters put a lot of strain on a water heater
Your water heater runs from September through May, nine months a year, and on winter nights that average 3°F it has to work harder to keep the tank at temperature. That kind of steady demand is what wears out a heating element or burner assembly before its time, and it is why a water heater that has been fine for years can start struggling in the coldest stretch of winter.
Cass County has also seen 68 winter storms and 172 damaging wind events over the past ten years, and statewide, 7 percent of households lost power for 24 hours or more in 2024. If the power drops, a standard electric water heater will not heat until it is back on.

A new water heater would cut about $260 a year off hot water for a typical North Dakota 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 reason is that the tank itself has corroded through and is failing. Sediment builds up at the bottom of the tank over years, and it eats away at the lining from the inside until a small hole forms. Water can also drip down from a loose fitting or a failing valve higher up on the tank, so it is worth drying everything off and checking where the water first appears. If the leak is coming from the tank itself, the tank needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- This is usually the thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep the gas flowing. When it wears out or gets coated in soot, it stops sensing the flame and the valve shuts the gas off. A dirty or misaligned pilot orifice can cause the same problem by keeping the flame too small or too far from the thermocouple. Either way, a contractor can test the thermocouple and replace it if it is bad.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is a common issue, especially since tankless units heat water on demand and scale can restrict flow over time. Igniters, flow sensors, and venting problems can also be diagnosed and fixed without replacing the whole unit. A contractor can flush the system or replace the specific part that has failed.
