Laredo doesn't ask much of a water heater, until the power goes out
Winters here are short and mild. Homes only need heat from December through February, and even then nighttime temperatures average 47°F. A new water heater in Laredo isn't working against the kind of cold or long heating season that wears one out further north.
The bigger question is what happens when the power drops. A third of Texas households went at least 24 hours without power in 2024, and Webb County has logged 31 damaging wind events over the past ten years alongside 2 winter storms. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electronic ignition will not, until power is back. Whatever size or type you choose, it also has to meet the federal minimum efficiency for its class, set by a formula tied to the tank's rated volume rather than one number for every heater.

A heat pump water heater would save about $290 a year to run in Texas compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check, and a contractor can tell you where your unit stands for its type. Once a tank is old, a repair is just a delay before the next problem. Look for rust colored water from the hot side, a tank that's damp or wet around the base, or water that never gets quite as hot as it used to. A tank that's actually leaking from the tank itself, not a fitting, needs to be replaced, not repaired, because that means the steel has failed.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water as it flows through, so it doesn't run out the way a tank does when several showers happen back to back. It also takes up less space than a tank. Whether it's worth it for your house is something a contractor can walk through with you, since the right size depends on how much hot water your home actually uses at once.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, so it doesn't run out during back to back showers. Tankless units also need more gas flow or electrical capacity than a tank did, so the gas line or the electrical circuit sometimes has to be upgraded to feed it. Venting is different too, since a tankless unit vents differently than a tank and that often means new venting has to be run. A contractor can look at your gas line, electrical panel, and where the unit will go before quoting the job, since those details decide what else needs to change.
