What a new water heater needs to handle in Dunn
Winter nights in Dunn average 33°F from December through February, and the heating season here runs October through March, six months a year. Your water heater works harder through those months, warming water that starts out colder for longer stretches of the year.
Power doesn't always stay on when it's needed most. Harnett County has seen 5 winter storms and 76 damaging wind events over the past ten years, and a quarter of North Carolina households went at least 24 hours without power in 2024. A gas water heater with a standing pilot will keep making hot water through an outage. One with electric ignition or an electric tank won't fire back up until the power does, though most start again on their own once it's back. Either way, a new installation is worth planning around that risk.
Federal efficiency minimums for storage water heaters aren't one number. They're set by a formula tied to the tank's rated volume, and that formula is applied differently across four draw patterns. Two tanks of the same type but different sizes can face different minimums, so the right efficiency standard depends on the unit going in, not a single rule for all of them.

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?
- Look at how it's failing, not just its age. Rust colored water, a tank that's rusting on the outside, water pooling underneath, or a pilot that won't stay lit are all signs the tank itself is going, not just a part. A leak from the tank means replacement, since a leaking tank can't be patched. If the tank looks fine and the problem is something like a heating element or thermostat, a contractor can tell you whether a repair is enough or whether you're better off replacing it now.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. Tankless units heat water on demand instead of storing it, so you don't run out partway through a shower, and they don't sit there keeping a tank of water hot all day. They also take up much less space than a storage tank. The tradeoff is that a tankless unit usually needs different venting and gas line sizing than what's already in place, so switching isn't a straight swap. A contractor can look at your gas line, venting, and water use and tell you whether tankless fits your house.
- What changes when you install a tankless water heater?
- The unit itself is much smaller, so it usually mounts on a wall instead of standing on the floor. Gas fired tankless units need enough gas flow to fire at full output, which often means checking or upsizing the gas line. Venting is different too, since tankless units vent differently than a standard tank and the existing vent usually can't be reused as is. None of this rules out switching, but it means the installation involves more than disconnecting the old tank and hooking up the new one. A contractor can walk through what your specific house would need.
