What a Boone County winter asks of your water heater
Winter nights here average 26°F from December through February, and the incoming water your heater has to warm starts out cold for months at a stretch. That is a longer, harder stretch than a water heater in a warmer climate ever has to work through.
Power is the other piece. Nearly a quarter of Kentucky households went at least 24 hours without power in 2024, and the region has logged 86 damaging wind events and 14 winter storms over the past ten years. A storage tank holds hot water through an outage. A tankless unit needs power to fire up, so it stops delivering hot water the moment the lights go out. Either way, when the power comes back on, most water heaters restart on their own without anyone resetting a switch.
Whatever size and type you install, it has to meet the federal minimum efficiency for that tank's rated volume. The minimum is not one number across the board. It is set separately for different draw patterns, so the right minimum depends on the size of the heater going in.

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 thing to check, and a contractor can tell you where yours stands against its expected life. Rust colored water, a tank leaking or sweating around the base, or water that won't get hot anymore are all signs the tank is failing. A heater that's noisy, especially rumbling or popping sounds, usually has sediment built up at the bottom, and that shortens what's left of its life. If you're calling for repairs more than once a year, replacing it is usually the better move over patching it again.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just what you have now. 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 warm around the clock. They also take up less space, since there's no tank to fit somewhere in the house. The tradeoff is that a tankless installation often means changes to the gas line, venting, or electrical setup, so it's not always a straight swap. A contractor can look at your house and tell you what that would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is what the unit needs to run, not just what it does. Tankless heaters draw more gas or electricity in short bursts than a tank does, so the gas line, electrical circuit, or venting may need to be upsized to handle it. They mount on a wall instead of sitting on the floor, which frees up space but means the location has to work for venting and water lines. Because this is new equipment, the local building office will require a permit and an inspection once the work is done, and a contractor can walk through what your specific house needs before the swap.
