Water heaters in Jackson work through a long, cold season
Winter nights here average 32°F from December through February, and homes run their heat October through April, seven months a year. A water heater has to work through that same stretch, warming water that starts out colder for most of the year than it does in summer.
Madison County has seen 14 winter storms and 45 damaging wind events over the past ten years, and across Tennessee, 20% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps running through an outage. One with electric ignition will not light again until the power is back. Whatever you install, a new tank has to meet the federal minimum efficiency set for its size and type, so the right model depends on how many gallons you need, not just the brand.

- How do I know it's time to replace my water heater?
- Water pooling at the base of the tank means it's time, since that's usually the tank itself failing and not a fitting you can tighten. Rusty hot water, a tank that's old, or a unit that can't keep up with the hot water your house needs are the other signs. If the tank is leaking from the bottom, replacement is the only fix. A cracked tank can't be patched or resealed.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on any rule that says tankless is better. A tankless unit heats water as it flows through instead of storing it, so you get hot water for as long as you run it, but the flow rate at any moment is limited by the unit's size. If your household regularly runs out of hot water with a tank, that's the strongest reason to look at tankless. If a storage tank has kept up fine, there's less reason to change.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit needs a gas line, vent, or electrical circuit sized for it, and the ones running to your old water heater often aren't a match. A tankless unit draws more gas or more power at the moment it's heating water than a tank does, because it has to heat that water fast instead of ahead of time in storage. That's why installation usually means new venting, a larger gas line, or an upgraded circuit, not just swapping one unit for another. A contractor can look at what's already run to your water heater and tell you what needs to change for a tankless unit specifically.
