What a new water heater has to handle here
Winter nights in Bernalillo County average 23°F from December through February, and homes here run their heat from October through April. A water heater sits through that same cold, especially if it's in a garage or an unconditioned space, and the incoming water it has to warm is colder for those seven months than the rest of the year.
Power doesn't always stay on through a storm. The area has logged 79 winter storms and 155 damaging wind events over the past ten years, and statewide, 13% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One that depends on power to ignite will not, and won't come back on until power is restored.
Every new storage water heater has to meet a federal minimum efficiency rating, and that minimum is set by the tank's size and how it's used, not one number for every unit. Two tanks of the same type can have different minimums to meet depending on their rated volume.

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 water pooling around the base of the tank. That means the tank itself is failing, not a fitting or valve, and it will not get better. Rust-colored water, a tank that's making rumbling or popping sounds, or water that won't get hot anymore are the other signs worth acting on. If your water heater is over 10 years old and giving you any of these problems, replacing it makes more sense than repairing it. A contractor can look at the specific unit and tell you whether it's a repair or a replacement.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water on demand instead of storing it, so you don't run out of hot water partway through a shower, and it doesn't sit there keeping a tank of water hot all day when nobody's using it. What it won't do is deliver hot water instantly at the tap. It still has to fire up and heat the water as it flows, so there's a short wait, similar to what you have now. Whether the switch is worth it depends on your household's hot water use and the layout of your home, which is something a contractor needs to look at in person.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as you use it. That means no standby losses from a tank sitting full of hot water between uses. It also usually means different venting and gas line requirements than your old tank had, since a tankless unit needs enough gas flow to heat water fast, and the venting has to match the unit. Some homes need upgrades to the gas line or electrical to support it. A contractor can walk through your home's setup and tell you what's needed for yours.
