What a water heater in Maury County has to deal with
Winter nights here average 30°F from December through February, and that is the water coming into the tank right when the house is asking the most of it. A new water heater has to recover from cold water like that every day, all winter, not just on the odd hard morning.
Power doesn't always stay on to do that work. 20% of Tennessee households went at least 24 hours without power in 2024, and the state has seen 9 winter storms and 104 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 an igniter won't light until the power is back.
The federal efficiency minimum for storage water heaters isn't one number. It's set by a formula tied to the tank's rated volume, applied separately across four different draw patterns. Two tanks of the same type but different sizes can be held to different minimums, so the right figure depends on the size of the tank going in.

A heat pump water heater would save about $280 a year to run in Tennessee compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age, and a contractor can tell you where your unit stands once they see the tank and its rating plate. Water pooling around the base usually means the tank itself is failing, and no part can fix that. Rusty hot water, a tank that's noisy when it heats, or hot water that runs out faster than it used to are also signs the tank is wearing out rather than having one bad part. If the problem is something specific, like no hot water or a pilot that won't stay lit, and the tank isn't old, that's usually a repair, not a replacement.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on anything specific to your area. A tankless unit heats water as you use it instead of storing a tankful, so you don't run out of hot water partway through a shower, and it takes up much less space than a tank. It costs more upfront and needs different venting and gas line sizing than a tank, so it's a bigger change to the plumbing and venting in your home than a straight tank swap. If your current tank still has good years left, there's no rush. If you're replacing it anyway, it's worth asking a contractor whether your gas line and venting can support tankless before you decide.
- What changes when you install a tankless water heater?
- The venting changes first. Tankless units need their own venting sized for the unit, and that's usually different from what a tank used, so the old vent pipe typically can't just be reused. Gas line sizing often changes too, since a tankless unit can draw more gas at once than a tank does, even though it only fires when you're using hot water. The unit itself mounts on a wall instead of sitting on the floor, so you gain floor space where the old tank stood. A contractor will need to check your home's existing gas line and venting to know what has to be upgraded before installation.
