What a water heater in Georgetown County has to handle
Winters here are mild, down to about 38°F on winter nights, and homes only need heat November through March. A water heater doesn't face the workload it would further north. But it runs on the same power grid that storms in this county test hard. Georgetown County has recorded 45 damaging wind events over the past ten years, and in 2024 nearly half of South Carolina households lost power for 24 hours or more at some point. A gas water heater with a standing pilot comes back on by itself when the power returns. One with electric ignition needs power to relight.
When you install a new one, the tank size matters for more than fitting the space. Federal efficiency minimums for storage water heaters are set by a formula tied to the tank's rated volume, and that formula works differently across draw patterns, so two tanks of different sizes don't meet the same number. Whoever installs yours needs to size it to how much hot water your household actually uses, not just the footprint where the old one sat.

A heat pump water heater would save about $300 a year to run in South Carolina compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Most tanks last about a decade, and past that point the tank itself is more likely to fail than any part inside it. Look for rust-colored water, a tank that's damp or sweating at the base, or water pooling underneath it. If it's making popping or rumbling sounds, sediment has built up on the bottom and the heater is working harder to do the same job. A younger unit with none of these signs is usually worth repairing instead.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is failing. A tankless unit heats water on demand, so you don't run out during a long shower or back to back loads of laundry, and there's no tank of water sitting around losing heat between uses. It also takes a different setup than a tank, sometimes different venting or gas line sizing, so it's worth having a contractor look at your specific house before deciding.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes limited by flow rate instead of tank size. A tankless unit heats water as it passes through, so it won't run cold partway through a shower, but it also has a maximum number of gallons per minute it can heat at once, so running two showers and a dishwasher at the same time can stretch it thin. The install itself is different too. Tankless units often need venting rated for their exhaust temperature and, depending on the model, a gas line sized for their higher demand. A contractor can tell you what your house needs to make the switch.
