A water heater in Miami-Dade runs every day, all year
There's no winter here to slow it down. Homes in the county need 0 months of heat a year, and winter nights only average 59°F. Your water heater doesn't get a season off. It heats water at the same pace in every month, which adds up to more running hours over its life than a unit further north ever sees.
Power loss is worth planning for too. Statewide, 38% of households went at least 24 hours without power in 2024, and the county has logged 80 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps running through an outage. One with electric ignition won't light until power is back, though most units restart on their own once it is.
When you install a new tank, it has to meet the federal minimum efficiency, and that minimum isn't a single number. It's set by the tank's size and by how a household draws hot water, so two tanks of different sizes can face different minimums on the same install.

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?
- Water pooling around the base or rust colored water from the hot tap means the tank is failing. A tank that makes rumbling or popping sounds is dealing with sediment buildup at the bottom, which makes it work harder and fail sooner. Age matters too. If yours is old and starting to act up, get it looked at before it lets go, since a burst tank can put a lot of water on the floor fast.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your climate here since winter nights rarely get cold enough to matter for this decision. A tankless unit heats water on demand instead of holding a tankful hot around the clock, so it can mean lower standby losses and it won't run out of hot water partway through a shower. Installing one 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 home's setup and tell you what switching 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 with a tank. Because it heats water only when a tap opens, it needs a gas line or electrical circuit sized for that burst of demand, which is often bigger than what the old tank used. Venting changes too, since tankless units vent differently than a standard tank. Any of this may mean modifying what's already run to that spot in the house, so a contractor needs to see the space before saying what the job involves.
