Ashland asks a lot of a water heater
Winter nights here average 26°F from December through February, and the house needs heat from October through April, seven months of the year. A water heater is working right alongside the furnace through most of the year, not just a few cold weeks.
Power doesn't always stay on to run it. Kentucky saw 24% of households lose power for at least 24 hours in 2024, and the area has logged 12 winter storms and 49 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition won't light until the power is back. Whatever gets installed here should be sized and set up with that in mind, and it has to meet the federal minimum efficiency for its tank size, a figure set separately by size and draw pattern rather than as one number for every heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Most tank water heaters last around 10 to 12 years, and once you're past that, a repair is often just a delay before the next one. Watch for rusty water coming from the hot tap, a tank that's damp or rusted at the seams, or popping and rumbling sounds as sediment builds up on the bottom. If you're not getting hot water the way you used to, or a puddle shows up under the tank, that unit is telling you it's done. A contractor can look at the tank and tell you whether it's worth repairing or whether replacement is the better call.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, but there are real trade-offs either way. A tankless unit heats water on demand instead of holding a tank full of it, so you don't run out of hot water partway through a shower with the dishwasher running. It also takes up much less space than a tank. On the other side, tankless units cost more upfront to install, and if your home runs on gas, some models need a larger gas line or a different vent than what's there now. A contractor can look at your home's setup, your gas line, your venting, your hot water use, and tell you whether tankless makes sense for your house specifically.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets heated as you use it instead of stored ahead of time. That means no standby tank losing heat, and in most cases, an endless supply of hot water as long as the unit can keep up with demand. It usually means new venting, since tankless units vent differently than a tank does, and in some cases a bigger gas line to supply enough fuel for the burner. The unit itself mounts on a wall and takes up a fraction of the floor space a tank does. Because the installation involves gas line and venting work, it needs a permit and inspection from the local building office, same as any water heater installation here.
