Travis County winters are short, but the power isn't always on
Water heaters here work through a short, mild season. Homes only need heat November through March, and winter nights average 40°F, so the tank itself is not fighting hard weather most of the year.
The bigger risk is what happens around it. Texas saw a third of households lose power for 24 hours or more in 2024, and Travis County has logged 9 winter storms and 103 damaging wind events over the last ten years. A gas water heater with a standing pilot keeps making hot water when the power drops. One that relies on electronic ignition will not, until the power comes back. Whatever you install, it has to meet the federal minimum efficiency for its size and type, which is set separately for each tank volume rather than as 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?
- The clearest sign is water pooling around the base of the tank. That usually means the tank itself is leaking, and a leaking tank can't be repaired. Rusty or metallic-tasting hot water, water that won't get as hot as it used to, or popping and rumbling sounds from sediment buildup are all signs the tank is failing. A licensed contractor can check the anode rod and the tank's condition and tell you whether a repair still makes sense or whether replacing it is the better move.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says tankless is better. A tankless unit heats water only when you're running a tap, so you're not paying to keep a tank of water hot all day, and it won't run out partway through back-to-back showers. What it won't do is deliver hot water instantly at the tap. It still has to heat the water as it flows, so there's a short wait at the fixture just like with a tank. Whether switching is worth it comes down to your household's hot water use and what your home can support, and that's something a contractor should look at directly.
- What changes when you install a tankless water heater?
- The biggest change is venting and gas supply. A tankless unit needs its own dedicated venting, sized differently than a tank's, and often needs a larger gas line because it heats water on demand at a higher rate than a tank does. Electrical requirements can change too, since some tankless units need power for ignition and controls even on a gas model. Space changes as well, since a tankless unit mounts on the wall and frees up the floor space a tank used to take. Because the venting, gas line and mounting location all depend on the house, a contractor needs to look at it before saying exactly what the install involves.
