What a water heater in Anderson County has to deal with
Winter nights here average 34°F from December through February, and homes need heat from November through March, five months a year. Through that stretch the water entering the tank runs cold, and a new water heater has to make up more of that difference before it reaches the shower or the dishwasher.
Power is the bigger issue. Across South Carolina, 45% of households went at least 24 hours without power in 2024, and the county has recorded 111 damaging wind events over the past ten years. Most tank water heaters with electric ignition come back on by themselves once power returns, but they will not run without it. A gas unit with a standing pilot keeps making hot water through an outage since it does not need power at all. Whatever type goes in, it has to meet a federal efficiency minimum that is not one fixed number. It is a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes can face two different minimums.

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 water pooling at the base of the tank. That means it has started to fail on the inside, and it will not seal itself back up. Rusty water from the hot tap, a tank that makes a rumbling or popping sound, or water that will not get hot anymore are the other signs to watch for. Age matters too, so if yours is old and starting to act up, replacing it before it fails outright means you get to choose the timing instead of dealing with a flooded closet.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you do not run out partway through a shower, and it does not sit there holding a tank of hot water when nobody is using it. Switching usually means changes to the gas line, the vent, or the electrical circuit, since tankless units have different requirements than a storage tank. A contractor can look at your home and tell you what that switch would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, but what changes around it depends on your home. Gas tankless units often need a larger gas line than a storage tank used, because they draw more gas in the moment to heat water fast. The venting is different too, usually a dedicated line to the outside rather than sharing a flue. Electric tankless units draw a lot of power at once, which can mean an upgrade to the circuit or panel. None of this means you cannot make the switch, it just means the installation involves more than swapping one unit for another, and a contractor will need to see your setup to know what's needed.
