Asheville winters ask more of a new water heater
Buncombe County needs heat from October through April, seven months of the year, with winter nights averaging 28°F. A water heater runs through that same stretch, and whatever goes in has to hold up to it season after season.
The county has recorded 8 winter storms and 55 damaging wind events over the past ten years, and across North Carolina a quarter of households lost power for at least a day in 2024. A gas water heater with a standing pilot keeps making hot water when the power goes out. One with electric ignition will not, though most restart on their own once power is back. Whatever size or type goes in, it has to meet a federal minimum efficiency, and that minimum is set separately for the tank's size and how the home draws hot water.

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?
- The clearest sign is water pooling around the base of the tank, since that means it's leaking and won't be repaired. Rust-colored water, a tank that's rumbling or popping, or hot water that runs out faster than it used to are all signs the tank is wearing out inside. Most storage water heaters last a decade or so before problems like these show up. If yours is that old and starting to act up, get it looked at before it fails outright and floods the space around it.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry, but it needs enough gas supply or electrical capacity to fire at that rate, and venting suited to the unit. A contractor can look at your gas line, your electrical panel, and where the unit would go, and tell you whether your home is set up for it or what it would take to get there.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That usually means new venting, since tankless units vent differently than a tank does, and it may mean a larger gas line or a dedicated electrical circuit depending on the model. The unit itself is smaller and mounts on a wall, which frees up the floor space the old tank used. A contractor can walk through what your home's gas, power, and venting can support before deciding on a unit.
