What Round Rock asks of a water heater
Winter nights here average 40°F from December through February, and homes only need heat from November through March. A water heater in this county isn't fighting hard cold most of the year, but the storms that come through can still take the power out. Williamson County has seen 10 winter storms and 58 damaging wind events over the past ten years, and across Texas a third of households lost power for at least 24 hours in 2024. If your water heater runs on electricity, an outage that long means no hot water until it's back.
New storage water heaters also have to meet a federal efficiency minimum, and that minimum isn't one number. It's set by a formula tied to the tank's rated volume, applied separately across four draw patterns. Two tanks of the same type but different sizes can face different minimums, so the right model depends on the size of the tank and how the household draws hot water, not just the type of 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 age. Most tank water heaters last about a decade, and past that point the tank itself is more likely to fail than any part inside it. Watch for water pooling around the base, which usually means the tank is rusting from the inside out and won't be fixed with a repair. Rusty water from the hot tap, a pilot that won't stay lit, or hot water that runs out faster than it used to are all signs the tank is wearing down rather than having a one-off problem. If your unit is still fairly new and the issue is something like a faulty thermostat or heating element, a repair may still make sense, and a contractor can tell you which situation you're in.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water supply. A tankless unit heats water as it's used instead of storing a tankful, so you don't run out partway through a shower, and it takes up much less space than a tank. It's a bigger job than a straight tank swap, since it often means changes to the gas line, venting, and sometimes the electrical to meet what the tankless unit needs. A contractor can look at your current setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, so where it sits in your home usually changes. Because it heats water on demand rather than storing it, it often needs a larger gas line to deliver enough fuel in the moment, and its venting is different from a tank's, sometimes requiring new venting runs entirely. Some models also need a dedicated electrical circuit to run their controls, which a standard tank water heater doesn't require. All of this means the installation involves more than swapping one unit for another, and a contractor will need to look at your gas line, venting, and electrical to tell you what's needed in your specific home.
