What a Grants winter asks of your water heater
Grants gets cold at night, down to 18°F on average from December through February, and homes here run their heat from October through May. Eight months of cold groundwater feeding into the tank means it works harder to bring water up to temperature than it would in a milder place.
Winters in this area also bring storms, 36 of them over the last ten years, along with 89 damaging wind events. Power loss is not rare in New Mexico, where 13% of households went at least a day without it in 2024. A gas water heater with a standing pilot will keep making hot water through an outage. One that runs on electricity to ignite or operate will not come back on until the power does, though most start up again by themselves once it's restored. Either way, a new installation is worth planning around what happens here when the power drops.
New storage water heaters also have to meet a federal minimum efficiency, and that minimum is not one number. It is set by a formula tied to the tank's size and to how the home draws hot water, so two tanks of different sizes can face different requirements even if they are the same type.

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, most tank water heaters have a limited run of years before failure becomes a matter of when, not if. Rusty water from the hot tap, a tank that's damp or rusted at the base, or water that never gets quite as hot as it used to are all signs the tank is on its way out. If a contractor is already telling you the tank has a leak, that one is not worth repairing. A leaking tank means the steel has failed inside, and that only gets worse.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is failing. A tankless unit heats water only when you turn on a hot tap, so you're not paying to keep a tank of water hot all day. It also won't run out of hot water partway through a shower the way a tank can when several people use it back to back. What it won't do is deliver hot water instantly at the tap, there's still a short wait for the water in the pipe between the heater and the fixture to heat up. A contractor can look at your gas line, venting, and water use and tell you whether tankless makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is what's on the wall. A tankless unit is small and mounts flat, instead of the tall tank taking up floor space in a closet or utility room. Gas tankless units usually need a bigger gas line than a tank water heater used, because they draw more fuel to heat water on demand, and they need their own venting to the outside. Electric tankless units instead need enough amperage on the electrical panel to run them. Any of these can mean extra work beyond just swapping one unit for another, so it's worth having a contractor check your gas line, vent path, or panel capacity before you decide.
