Sanford doesn't ask much of your water heater, until the power goes out
Winters here are mild. Nights average 51°F even in the coldest months, and most homes only need real heat in December and January. A water heater in Seminole County isn't fighting the cold most of the year.
The bigger risk is the storms. The county has logged 30 damaging wind events over the last ten years, and statewide, 38% of households lost power for at least 24 hours in 2024. If you're choosing between a tank and a tankless unit, or between gas and electric, that outage risk is worth weighing alongside everything else. Whatever you install has to meet the federal minimum efficiency for its size and type, since the rules are set separately for each tank volume.

A heat pump water heater would save about $240 a year to run in Florida compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age, since a tank water heater weakens from the inside as it gets older and eventually the tank itself starts to fail. Rust colored water, a tank that's damp or wet at the base, or water that runs lukewarm no matter how you adjust it are signs of a failing tank rather than something you can repair. A popping or rumbling sound means sediment has built up on the bottom, and while that alone doesn't mean replacement, it's worth having someone look at the unit and tell you which situation you're in.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water only when you run a tap, so you don't pay to keep a tank of water hot all day, and you won't run out of hot water partway through back to back showers. Switching from a tank usually means changes to the gas line, venting, or electrical circuit, since tankless units draw more power at the moment they fire than a tank does. A contractor can look at your current setup and tell you what that switch would involve in your house.
- What changes when you install a tankless water heater?
- The unit itself is the biggest change. It mounts on a wall instead of sitting on the floor, and it's roughly the size of a suitcase rather than a large tank, so it frees up floor space. Because it heats water on demand instead of storing it, it usually needs a larger gas line or a dedicated electrical circuit than the old tank used, along with venting rated for its higher heat output. Whether your home's existing gas line, electrical panel, or venting can support that without upgrades is something a contractor has to check at the house.
