What Rio Rancho winters do to a water heater
Your water heater works harder from October through May, when incoming water runs cold and the tank has to make up more ground to hit temperature. On nights that average 19°F, a unit in a garage or an outdoor closet loses heat faster than one indoors, and the burner or element cycles more to keep up. That extra cycling wears on the thermostat and the heating element or gas valve over time.
Sandoval County has logged 134 winter storms and 121 damaging wind events over the past ten years, and storms like these knock out power. If yours does, a gas water heater with a standing pilot keeps working, but an electric one or a gas unit with an electronic ignition will sit cold until power comes back and may need the pilot relit by hand.

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 once that happens the tank needs to be replaced, not patched. Water at the bottom can also come from loose drain valve, a leaking cold water inlet fitting, or a pressure relief valve doing its job because pressure inside the tank is too high. A contractor can tell the difference quickly by drying the area and watching where the water shows up first. If it is the tank itself, shut off the water and power to the unit until it can be replaced.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually a thermocouple that has worn out and stopped sending the signal that tells the gas valve it is safe to keep the flame on. It can also mean a draft is blowing the flame out, or the gas valve itself is failing. A thermocouple is a simple, inexpensive part to swap out, so that is where a contractor will check first. If it keeps happening after a new thermocouple, the gas valve is the next thing to look at.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, a clogged inlet filter, and error codes from the flow sensor are all things a contractor can diagnose and fix without replacing the unit. Tankless units run for many years when the heat exchanger is flushed on a regular schedule, since hard water buildup is what causes most of the failures. A contractor can check the error code on the display and go from there.
