Portales winters put a real load on your water heater
December through February, nights here average 26°F. Cold water coming into the tank takes more energy to heat, and the burner or element runs longer to keep up. Over October through April, that is seven months of harder work every year.
Power does not always stay on through a winter storm. Roosevelt County has seen 6 winter storms and 53 damaging wind events over the past ten years, and statewide, 13% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition will not light until the power is back.
New water heaters 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 rated volume, and it is worked out separately for four different draw patterns. Two tanks of the same type but different size can face different minimums.

A heat pump water heater would save about $230 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?
- If it's leaking at the tank itself, replace it. That's rust working through the steel from the inside, and it doesn't stop or get patched. Other signs point the same way. Water that isn't as hot as it used to be. A tank making rumbling or popping sounds from sediment buildup. Rusty water coming from the hot tap only. A contractor can check the age and condition of your unit and tell you whether repair still makes sense or replacement is the better call.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water only when you run a tap, so you don't pay to keep a tank full of hot water sitting around all day. It also means you won't run out of hot water partway through a long shower or back to back loads of laundry, since it's not limited by tank size. The tradeoff is that tankless units usually need a gas line sized for their higher burner output, or for electric models, more amperage than a tank heater draws. A contractor can tell you whether your home's gas line or electrical panel can support the switch.
- What changes when you install a tankless water heater?
- The water heater itself changes from a tank to a wall-mounted unit about the size of a suitcase. Because it has no tank, it also needs no space for one, which opens up a closet or corner that used to hold the old heater. Venting changes too. Most tankless units are direct vent, using dedicated intake and exhaust pipes run to the outside, rather than sharing a flue with other appliances. The gas line or electrical circuit feeding it may need to be upsized, since a tankless unit calls for more power at the moment it's heating water than a tank does. A contractor can walk through what your specific setup will need.
