What a new water heater needs to handle here
Brownsville barely asks anything of a heating system. Homes here only need heat in December and January, and even then winter nights average 53°F. A water heater in this climate spends most of the year just keeping up with hot water use, not fighting off cold.
The bigger question is what happens when the power goes out. A third of Texas households lost power for 24 hours or more in 2024, and Cameron County has logged 95 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electric ignition or an electric heating element will not come back on until the power does, though most start back up on their own once it returns. Whatever the setup, a new installation has to meet the federal minimum efficiency for its tank size, since the standard is a formula that changes with how much hot water a household draws, not one number for every tank.

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 clearest sign. Most tank water heaters last about a decade, and once you're near or past that mark, a repair is often just a delay. Rusty water from the hot tap, a tank that's damp or rusted at the base, or water pooling underneath means the tank itself is failing, and that's not something a contractor can patch. If it's still running fine and well under that age, a repair may make more sense than a full replacement, so have a contractor check it before you decide either way.
- 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 on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry. It also takes up less space than a tank. Whether it fits your home comes down to your gas line, venting, and water use, and a contractor can walk through that with you.
- What changes when you install a tankless water heater?
- The biggest change is that hot water doesn't run out. A tank heater gives you a set amount before it needs time to recover, but a tankless unit heats water as it flows through, so it keeps up as long as the demand doesn't exceed what the unit can handle at once. That also means the gas line and vent, and sometimes the electrical hookup, may need to be upsized to match the unit, since it draws more at the moment it's running than a tank does. It also means losing the storage tank's footprint, since a tankless unit mounts on the wall and takes up a fraction of the space.
