Concord homes run their water heater hard, seven months of cooler weather a year
From October through April, incoming water runs colder and your water heater works harder to bring it up to temperature, with winter nights here averaging 32°F. That is seven months of steady demand on the tank and the burner or element inside it.
Power loss is a real factor here too. A quarter of North Carolina households went at least 24 hours without power in 2024, and Cabarrus County has logged 7 winter storms and 60 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition needs power to light, and most electric water heaters simply pick back up once power returns.
Any new storage water heater installed now has to meet the federal efficiency minimum, and that minimum is not one flat number. It is set by a formula tied to the tank's rated volume, applied separately across different draw patterns, so a larger tank and a smaller one of the same type answer to different minimums.

A heat pump water heater would save about $300 a year to run in North Carolina compared with an electric water heater.

- How do I know it's time to replace my water heater?
- If the water coming out runs rusty, if you hear rumbling or popping from the tank, or if you find water pooling at the base, the tank itself is failing rather than just one part. A leak at the tank means replacement, not repair, since the tank can't be patched. If none of that is happening and it's still heating water fine, a repair may be all it needs. 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 it, not on a rule that says everyone should switch. Tankless units heat water only when you turn on a tap, so they don't hold a standing supply that can run out during a long shower or back to back loads. They also take up less space than a tank and tend to last longer. Against that, they cost more to install and need a strong enough gas line or electrical circuit to run. A contractor can look at your home's setup and tell you what installing one would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. A tankless unit needs a gas line sized for its burner or an electrical circuit sized for its heating elements, and many homes need that line or circuit upgraded to meet it. Venting changes too, since tankless units vent differently than a tank and often need new venting run to the outside. Because there's no tank, the unit mounts on a wall instead of sitting on the floor, which frees up the space the old tank used. A contractor will look at your gas line, electrical panel, and venting to know what's needed for your house specifically.
