Elizabethton winters ask a lot of a water heater
Winter nights here average 27°F from December through February, and homes run their heat from October through May, eight months of the year. A water heater is working through most of that stretch too.
Power does not always stay on through a storm. Twenty percent of Tennessee households went at least 24 hours without power in 2024, and the area has logged 33 winter storms and 24 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps heating water through an outage. One that relies on an electric igniter will not light again until the power is back. Every new water heater has to meet a federal minimum efficiency, and that minimum is set by the tank's size.

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 combined with trouble. Once a tank is old, look for rust-colored water, a tank that's damp or wet around the base, or water that takes longer to heat than it used to. If a repair is going to cost close to a new unit, or the tank is actively leaking, replacement is the safer call. A leaking tank won't get better on its own, it will get worse.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on a rule that applies to every home. A tankless unit heats water on demand instead of storing it, so you don't run out during back to back showers, and it can run for many years past what a tank typically lasts. It does need enough gas supply or electrical capacity to fire fast, and venting suited to that specific unit, so a contractor needs to look at your home's setup before you decide. If your current tank is working fine, there's no rush. If you're replacing it anyway, it's worth asking what tankless would take in your house.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as you use it, so there's no tank to run out and no standby heat loss between uses. Because it heats on demand, it needs a burner strong enough to raise the water temperature fast, which usually means a bigger gas line or a dedicated electrical circuit depending on the unit. Venting is different too, tankless units vent through pipe sized and routed for that model, not the flue a tank used. Expect the install to touch the gas line, the vent, and sometimes the electrical panel, not just the spot where the old tank sat.
