Cold winters make your water heater work harder
From December through February, nights here average 30°F, and the water coming into the tank runs colder with them. Your heater has to work longer to bring it up to temperature, and that extra work falls on the same burner or element every time. A unit that was already struggling in warmer months often can't keep up once winter sets in, and that shows up as water that never gets fully hot, or a tank that takes longer to recover between uses.
Power loss is also part of living here. In New Mexico, 13% of households went at least 24 hours without power in 2024. Most water heaters come back on by themselves once power returns, but a unit with a pilot light needs it relit by hand, and until then there is no hot water at all.

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 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 corrodes until it gives way. A leak from the bottom can also come from a loose drain valve or a fitting, which a contractor can check before assuming the tank itself is bad. Once the tank is actually 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 thermocouple that has worn out and no longer signals the gas valve to stay open. A weak pilot flame, a draft blowing across it, or a clogged pilot orifice can also keep it from staying lit. If the flame won't hold even after relighting it a few times, the part needs to be replaced rather than adjusted.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a buildup of scale on the heat exchanger, a bad igniter, or an error code pointing to a sensor. A contractor can flush the unit, replace the failed part, or clear the fault depending on what's wrong. It's only when the heat exchanger itself has failed that replacement usually makes more sense than repair.
