What a Silver City winter asks of a water heater
Winter nights here average 27°F from December through February, and homes in Grant County need heat running October through April, seven months of the year. A new water heater has to bring cold water up to full heat through all of that, night after night, and how fast it recovers says a lot about how well it holds up here.
Power is worth planning for too. Across New Mexico, 13% of households lost power for 24 hours or more in 2024, and the area has logged 11 winter storms and 46 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage that would stop an electric one cold. The federal efficiency minimum for storage water heaters isn't one number either. It's set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so the minimum a given tank has to meet depends on its size.

A heat pump water heater would save about $340 a year to run in New Mexico compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age combined with trouble. Once a tank water heater is old, a unit that's slow to heat, rumbling from sediment, or leaking at the tank seams is telling you it's near the end. Water that runs lukewarm no matter how you adjust the thermostat, or rusty water from the hot tap only, points the same way. A leak at the tank itself, rather than a fitting or valve, means replacement, since a tank doesn't get patched. If your water heater sits in an unheated space, keep in mind winter nights here average 27°F, and a unit already struggling with sediment or a failing element has less margin in that cold.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry, and it takes up far less space than a tank. Switching usually means changes to the gas line, venting, or electrical circuit, since tankless units draw more power at the moment they fire than a standing tank does. A contractor can look at your home's gas supply and venting and tell you what the switch would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of standing on the floor, which frees up space in a closet or utility room. Because it heats water only when a tap opens, it needs a gas line sized for a larger, brief burst of demand than a tank ever asked for, and it needs its own vent run to the outside. Homes with a tankless unit lose stored hot water in a power outage, since the ignition and controls still need electricity even on a gas model. That's worth weighing here, where 13% of New Mexico households went at least 24 hours without power in 2024.
