What cold winters and hard freezes do to a water heater in Portales
Roosevelt County sees winter nights average 26°F from December through February, and the ground water coming into the tank is cold for the seven months homes here run heat, October through April. Your water heater has to work harder to bring that water up to temperature, and it runs more often to do it. That extra cycling wears on the heating element or the burner, and on the thermostat that tells it when to fire.
Winter storms also bring power loss. Across New Mexico, 13% of households went at least 24 hours without power in 2024, and Roosevelt County has recorded 6 winter storms over the past ten years. An electric water heater won't heat while the power is out, and when it comes back on, it has a full tank of cold water to bring back up to temperature. That's when a weak element or a failing thermostat tends to show itself, with water that never gets as hot as it used to, or runs out fast.

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 tank itself has likely rusted through and is starting to fail. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath rusts and eventually leaks. A leak can also come from a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the gas valve shuts off the pilot as a safety measure. A weak gas supply or a draft near the pilot can also blow it out. A contractor can test the thermocouple and replace it if that is the problem, since it is not something to force back into place.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a clogged inlet filter, a buildup of mineral scale on the heat exchanger, or a failed igniter, and each of those can be cleaned or replaced. The unit's error code usually points a contractor straight to the part at fault. Scale buildup is worth watching for since it reduces how well the unit heats water over time.
