What a Dallas County water heater has to deal with

Winter nights here average 38°F from December through February, and incoming water runs cold right along with them. A water heater has to make up that difference before it ever reaches your tap, and it does that work five months a year when homes here need heat, November through March.

Power is the bigger risk. A third of Texas households went at least 24 hours without power in 2024, and Dallas County has logged 22 winter storms and 145 damaging wind events over the last ten years. A gas water heater with a standing pilot keeps running through an outage. One with electronic ignition won't light until the power is back on. A new installation also has to meet a federal efficiency minimum that scales with the tank's size, so the exact standard depends on how many gallons it holds.

How do I know it's time to replace my water heater?
Water pooling around the base or rust-colored water from the hot tap is the clearest sign. So is a tank that's making rumbling or popping sounds, which usually means sediment has built up on the bottom and is starting to burn through the metal. Once a tank starts leaking from the tank itself rather than a fitting or valve, it needs to be replaced, not repaired. If yours is getting old and the water isn't heating like it used to, have a contractor look at it before it fails and floods the area around it.
Should I switch to a tankless water heater?
It depends on what you want out of it, not just on replacing what failed. A tankless unit heats water only when you're running a tap, so you don't pay to keep a tank of water hot all day, and you don't run out of hot water partway through a shower. Against that, a tankless unit costs more upfront and needs a contractor to check whether your gas line, venting, and electrical can support it. If your current tank is still working fine, this is a decision to make on your own timeline. If it just failed, a contractor can tell you whether your home is set up for tankless or whether a storage tank makes more sense right now.
What changes when you install a tankless water heater?
The biggest change is that a tankless unit hangs on the wall instead of taking up floor space, since there's no tank to hold. It also needs a larger gas line in most cases, because it has to heat water fast enough to keep up with a running faucet or shower, and it needs its own vent designed for that higher heat output. The venting and gas line work is why this isn't a straight swap for your existing tank. A licensed contractor has to check both before installation, not after, to make sure the unit gets enough gas and vents correctly.
