What a Moriarty winter asks of a water heater
Winter nights here average 21°F, and homes run their heat from October through May. A water heater sits in that same cold for eight months, working harder to bring tank water up to temperature when the incoming line runs cold too.
Torrance County sees its share of winter storms and wind events strong enough to knock out power, and across New Mexico about 13% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One that depends on electronics to ignite will not fire until power is back. Whatever gets installed, it has to meet the federal minimum efficiency for its size, which is set separately for each tank volume rather than as one flat number.

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?
- Watch for water that stays lukewarm, rust-colored water, or puddling at the base of the tank. Once a tank storage heater starts leaking from the tank itself, that's the tank rusting through from the inside, and it won't seal back up. Popping or rumbling sounds during heating point to sediment buildup at the bottom of the tank, which makes the burner work harder and can shorten what's left of its life. If the heater is original to the house and giving you any of these signs, it's worth having a contractor look at it before it fails outright.
- 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 and reheating a tank full, so you don't run out of hot water partway through back to back showers, and it doesn't sit there losing heat when nobody's using it. It won't heat water any faster per gallon, and it needs enough gas or electrical capacity to fire that hot on demand, which is something a contractor has to check for your house before swapping one in. If your current tank is working fine and just getting old, that's a reasonable time to have the conversation.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes limited by flow rate instead of tank size. You can run water as long as you want, but open enough fixtures at once and the unit may not keep up with all of them at full temperature. A tankless heater also needs a gas line sized for its burner, or a heavy electrical circuit if it's electric, and venting rated for its exhaust, which is often different from what the old tank used. Because of that, installing one is more than a swap, and a contractor will need to check the gas line, electrical panel, and venting in the house before sizing the unit.
