What types of water heaters are there?
Four types cover almost every Florida home: standard storage tanks, tankless (on-demand) units, and hybrid heat-pump water heaters — each available in electric or, where gas exists, gas versions.
Storage tank
The most common type — a 40–50+ gallon tank keeps a reservoir of hot water ready. Lower up-front cost and simple to service.
Tankless (on-demand)
Heats water only as you use it, so you never run out — though flow rate limits how many fixtures run at once. Compact and longer-lived.
Hybrid heat-pump water heater
Uses heat-pump technology to be highly efficient. Needs adequate space and air flow (often a garage) and a bigger up-front investment.
Deciding between the two most common options? Our tank vs. tankless comparison breaks down the trade-offs.
How long does a water heater last?
Plan on roughly 8–12 years for a tank water heater and 15–20 years for a tankless unit. Maintenance and water quality move you toward the top or bottom of those ranges.
Once a tank passes the 10-year mark, it's wise to start budgeting for replacement — especially if you've never flushed it. Planning ahead beats an emergency swap after the tank lets go and soaks the floor, garage, or closet around it.
How does Florida water affect a water heater?
Florida is well known for hard water — water with a high mineral content. Those minerals settle as sediment in a tank and as scale inside tankless units, cutting efficiency and shortening lifespan.
What hard water does
Sediment insulates the burner or element (wasting energy), causes that telltale popping sound, and accelerates corrosion. For tankless units, scale restricts flow and triggers error codes. A water softener or filtration system, plus regular flushing, are the best defenses — ask us to test your water if you're unsure.
What are the warning signs it's failing?
Most water heaters give plenty of warning before they quit. Call a plumber if you notice:
- Rusty, cloudy, or metallic-smelling hot water.
- Running out of hot water faster than it used to.
- Water pooling, dampness, or corrosion around the base.
- Popping or rumbling while it heats.
- It's more than 10 years old and slowing down.
How can I extend its life?
A little maintenance goes a long way, particularly in hard water:
- Flush the tank yearly to clear sediment (descale tankless units on schedule).
- Have the anode rod checked — it's the sacrificial part that fights corrosion.
- Set the temperature around 120°F to balance comfort, safety, and energy.
- Address small leaks and consider water treatment if your water is hard.
