What a Rowan County water heater has to handle
Winters here average 31°F, and the heating season runs seven months, October through April. That is most of the year that a water heater is working against cold incoming water.
Storms are part of living here too. Rowan County has seen 7 winter storms and 101 damaging wind events over the last 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 keeps making hot water through an outage. An electric one comes back on by itself once the power is restored. Whichever type goes in, it has to meet the federal minimum efficiency set for its size, which is figured separately by tank volume and draw pattern rather than as one number for every heater.

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?
- Check the data plate for the manufacture date first, since most tank water heaters wear out after so many years of daily use. If the tank is leaking at the base, that's the tank itself failing, not a part, and it means replacement, not repair. Rusty or metallic-smelling hot water, a pilot or igniter that keeps failing, or hot water that runs out faster than it used to are all signs the tank is on its way out. A contractor can tell you whether what you're seeing is worth repairing or whether the unit is at the end of its life.
- 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 only as you use it, so you don't run out during a long shower or back to back loads of laundry, and it takes up far less space than a tank. Switching usually means changes to the gas line, venting, or electrical circuit, since a tankless unit draws more heavily at the moment of use than a tank does. A contractor can look at your gas line and venting and tell you what the switch would involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made on demand instead of stored ahead of time. That means the gas line and venting often need to be resized, since a tankless unit calls for more gas flow in the moment than a tank does. The unit itself mounts on a wall rather than sitting on the floor, which frees up the space where the old tank stood. Electrical work may also be needed depending on the model. A contractor can walk through your gas, venting, and electrical setup and tell you exactly what has to change.
