Santa Fe County puts eight months of work on your water heater
Water heaters here run hard from October through May, when groundwater coming into the tank is already cold and the burner or element has to work longer to bring it up to temperature. On nights that average 20°F, a water heater in a garage or unconditioned space loses heat faster, so it cycles more just to hold the water where you set it. That extra cycling wears on the thermostat and the heating element or burner assembly over time.
Power loss adds to this. Statewide, 13% of households went at least 24 hours without power last year, and the county has logged 134 winter storms and 187 damaging wind events over the past ten years. A gas water heater with an electronic igniter will not relight itself after an outage, and you will notice cold water until someone resets it. An electric water heater usually comes back on by itself once power returns.

A new water heater would cut about $50 a year off hot water for a typical New Mexico 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 failing. Sediment builds up on the bottom of the tank over years, and it holds moisture against the steel until it corrodes and cracks. A loose drain valve or a fitting can also leak and look like it's coming from the bottom, so it's worth checking those first, but a crack in the tank means the water heater needs to be replaced, not repaired. A contractor can tell you which one you're dealing with in a few minutes.
- 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's safe to keep the gas flowing. When it wears out or gets coated in soot, it can't hold that signal and the gas shuts off even though the pilot lit fine a second ago. A weak gas supply or a draft blowing on the pilot can cause the same thing, so it's not always the thermocouple, but it's the most common cause by far. A contractor can test it and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Issues like error codes, ignition failure, or reduced hot water flow usually trace back to a part that can be replaced, such as the igniter or a sensor, or to mineral buildup on the heat exchanger from hard water. A contractor can diagnose the error code or symptom and tell you whether it's a repair or, in rare cases, something that calls for replacement.
