What winter in Laurel County asks of a water heater
December through February, nights here average 28°F. Cold ground water means your water heater works harder to bring it up to temperature, and it does that work daily from October through April, seven months a year.
Power is part of the picture too. Across Kentucky, close to a quarter of households lost power for 24 hours or more in 2024, and Laurel County has logged 16 winter storms and 115 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One that depends on electronic ignition will not light until power is back. Whichever you install, it has to meet the federal minimum efficiency for its size and type, which is set separately for each tank volume 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?
- Age is the first sign, and if yours has been in service a long time, a repair may only buy you a little more time before the next problem shows up. Rust-colored water, a tank rusting on the outside, or water pooling underneath all point to the tank itself failing, and a tank can't be repaired, only replaced. If it's struggling to keep up with hot water or making rumbling or popping sounds, that's sediment built up inside, and it's wear adding up rather than one bad part. A contractor can look at it and tell you whether what you're seeing is fixable or the tank reaching the end of its life.
- Should I switch to a tankless water heater?
- That depends on what you want from it, not on any rule that says newer is better. A tankless unit heats water as you use it instead of storing it, so you get a steady supply without a tank running out partway through a shower, and it takes up less space since there's no cylinder to hold. But a tankless heater usually costs more to install, and depending on your home's setup, it may need changes to the gas line or venting to handle it. A contractor who's seen your water heater and your home's setup can tell you if the switch makes sense for your situation.
- What changes when you install a tankless water heater?
- The biggest change is that hot water is made as you use it instead of stored ahead of time. That means no tank sitting full of hot water waiting, and no running out if a shower runs long or two things need hot water at once. Because there's no tank, a tankless unit needs different venting and often a different gas or electric connection than what's already there, which is why the installation looks different from swapping in a new tank. Replacing a water heater needs a permit from the local building office and an inspection when the work is done, so a contractor will need to account for that as part of the job. A contractor can walk you through what your specific home will need to make the switch.
