What a Gallup winter asks of your water heater
Winter nights here average 18°F from December through February, and homes in McKinley County need heat eight months a year, October through May. Your water heater runs through that same cold, and through the rest of the year too.
Power is not always reliable here. Across New Mexico, 13% of households went at least a full day without power in 2024, and the county has seen 44 winter storms and 64 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition will not light until power is back. Whichever type goes in, it has to meet the federal minimum efficiency for its size, since that standard is set separately for each tank volume and draw pattern rather than as one number for every heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank. That means the tank itself is failing, and once it starts it does not stop. Rusty hot water, a burning smell from the burner area, or hot water that runs out faster than it used to are also signs the tank is near the end. Age matters too. Most storage water heaters last a decade or so, and once one passes that mark, a contractor can tell you whether it is worth repairing or time to plan a replacement.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your current tank failing. A tankless unit heats water on demand instead of storing it, so you do not run out of hot water partway through a shower, and it takes up less space than a tank. It also runs on different venting and gas or electrical requirements than a storage tank, so switching is a bigger job than a straight tank swap. A contractor can look at your home's gas line, venting, and electrical setup and tell you what switching would actually involve here.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of sitting on the floor, so it opens up space a tank used to take. It needs its own venting, sized for the unit, and often a larger gas line or a dedicated electrical circuit than what fed the old tank. There is no standing pilot and no reservoir of hot water waiting, so the unit fires up each time you open a hot tap rather than keeping a tank warm around the clock. A contractor will check your home's existing gas line, vent path, and electrical panel to see what needs to change to support one.
