What a water heater in Henderson County has to handle
Winter nights here average 28 degrees from December through February, and homes run their heat from October through April, seven months of the year. A water heater is working the rest of the year too, and cold months put more demand on it.
Power is not something to count on. In Kentucky, 24% of households went at least 24 hours without power in 2024, and the county has seen 10 winter storms and 82 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on power to ignite will not, until the power comes back.
The federal minimum efficiency for a storage water heater is not one number. It is set by the tank's rated volume, so the right standard for a new one depends on the size it needs to be.

- How do I know it's time to replace my water heater?
- Water pooling at the base of the tank means it is failing and needs to come out. Rusty hot water, an older tank, or water that never gets as hot as it used to are all signs the heater is on its way out. If the tank itself is rusting on the outside or you hear rumbling from sediment built up inside, replacing it before it leaks is the safer call. A contractor can look at the age and condition of your unit and tell you whether repair still makes sense or whether replacement is the better move.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you do not run out during back to back showers, and it takes up far less space than a tank. Switching usually means changes to the gas line, venting, or electrical service, since tankless units draw more power at the moment they fire than a storage tank does. A contractor can look at your gas line size, venting path, and where the unit would go and tell you what the switch would actually involve in your house.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, which is the change most people notice first. Behind that wall, the gas line often needs to be a larger diameter to supply the burner at the rate a tankless unit demands, and the venting is different from what a tank uses. Tankless units also need access for periodic descaling, since minerals in the water build up inside the heat exchanger over time. A contractor can walk through what your home already has in place and what would need to change to support the new unit.
