Mandan winters put a lot of strain on a water heater
Groundwater coming into your house is cold most of the year here, with heat needed September through May. That means your water heater works harder and longer to get water up to temperature, and the burner or heating element cycles more to keep up. That extra cycling wears on the thermostat and the heating element in an electric tank, or the burner assembly in a gas one.
Winter nights averaging 6°F also mean a water heater in a garage or unheated space loses heat faster than it would in milder weather, so it runs even more to make up for it. And with 29 winter storms and 114 damaging wind events across the county over the past ten years, power interruptions happen. Most electric water heaters come back on by themselves once power returns, but a storm that knocks things around can also trip a breaker or loosen a connection that needs a look.

A new water heater would cut about $50 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?
- Most of the time this means the tank itself has rusted through and is starting to fail. Sediment builds up in the bottom of the tank over years, and it holds moisture against the steel until it corrodes and opens a small hole. A leak could also come from a fitting, the drain valve, or the temperature and pressure relief valve rather than the tank itself, and those can sometimes be repaired. A contractor can tell you which one it is, but once the tank itself is leaking, it needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn out 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, it fails to sense the flame fast enough and shuts the gas off. A dirty pilot orifice or a draft blowing the flame around can cause the same problem. This is a gas control issue, so it is worth having a contractor look at it rather than relighting it over and over.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. A failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or a bad flow sensor are all things a contractor can fix or replace without swapping out the whole unit. Tankless units also run diagnostic codes on a display or through a series of flashes, which point straight to the part that is failing. Full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
