What a Frankfort winter asks of a water heater
Winter nights here average 27°F from December through February, and the incoming water going into the tank is cold for most of the seven months homes run their heat, October through April. That is a long stretch of the year when a water heater is working from a colder starting point than it would in a milder climate.
Franklin County has also seen its share of hard weather, 10 winter storms and 51 damaging wind events over the past ten years, and 24% of Kentucky households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps working through an outage. One that depends on electronic ignition does not. Whatever is installed, it has to meet the federal minimum efficiency for its type and size, a standard that is set separately for each tank size rather than as one number across the board.

A heat pump water heater would save about $270 a year to run in Kentucky compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that no longer gets consistently hot, or a tank that's leaking from the bottom. Rust-colored water, a popping or rumbling sound from the tank, or water pooling around the base all point to a tank nearing the end of its life. Age matters too. Most storage tank water heaters last a decade or so, and once a unit gets past that point, a repair often just delays a replacement that's coming anyway. A leaking tank won't get better on its own, and it's worth having a contractor look at it before it fails outright.
- 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 back to back showers or laundry day. But installing one often means new venting and sometimes larger gas or electric supply lines, since tankless units draw more power at the moment they're heating. A contractor can look at your home's setup and tell you what changing over would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets heated as you use it instead of sitting ready in a tank. That means no standby heat loss, but it also means the unit needs to pull enough gas or electric supply to heat water fast, which can call for upgraded lines. Venting is different too. Tankless units typically need their own dedicated vent, sized and routed to match the unit, not the vent a tank heater used. Because of the venting and supply changes, this kind of swap usually needs a permit and an inspection from the local building office once the work is done.
