What a Plano water heater has to handle
Plano gets cold enough, December through February, that your water heater works harder pulling in tap water to heat. It's not the kind of cold that freezes pipes most years, but it adds to the load on the unit, especially during the five months homes here run their heat, November through March.
Power matters too. Statewide, a third of households went at least 24 hours without power in 2024, and Collin County has seen 22 winter storms and 86 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition does not, until the power comes back. Whichever type goes in, it has to meet the federal minimum efficiency for its size, since the standard is set separately for each tank volume.

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, so look at the data plate for the manufacture date and weigh that against what else it's telling you. If it's leaking from the tank itself, not a fitting or valve, that tank is done, since the steel has failed from the inside and it won't hold. Rusty hot water, a pilot that won't stay lit, or water heating slower than it used to are all signs the tank is near the end. A licensed contractor can check the anode rod and the tank condition and tell you whether repair still makes sense or whether you're better off replacing it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether a tank heater is somehow wrong. A tankless unit heats water on demand instead of storing it, so you don't run out partway through a shower with the dishwasher running. It also holds its efficiency better over time than a tank does, since there's no standing water losing heat while it sits. Against that, a tankless unit needs a gas line and venting sized for it, and not every home already has that in place. A contractor can look at your gas line, venting, and where the unit would go and tell you what installing one would actually involve in your house.
- What changes when you install a tankless water heater?
- The gas line and venting are usually what change most. A tankless unit fires at a much higher rate to heat water instantly, so it typically needs a larger gas line than a tank heater used, and venting rated for that unit specifically rather than a shared flue. It also mounts on a wall instead of sitting on the floor, which frees up floor space but means the location has to work for that. The federal efficiency minimum a water heater has to meet is set by its rated volume and draw pattern, so a tankless unit and the tank it replaces aren't held to the same number, and the rating on the new unit won't look like the one on the old tank. A contractor can size the gas line and venting correctly for the unit you're considering.
