Everything You Need to Know About Your Water Heater (Before It Surprises You!)

Your water heater works hard behind the scenes to keep showers hot, dishes clean, and daily routines or business operations running smoothly–until it doesn’t.

Ignoring it can lead to wasted energy, higher bills, and sudden cold showers (no one wants that!). Good news: a little care goes a long way.

Let’s talk about how to keep your system in top shape, and what to consider if it’s time to swap it out.

How to Maintain Your Water Heater

A few easy habits can keep your water heater humming and help you avoid messy (and expensive) surprises.

For tank-style water heaters

• Flush annually to clear out sediment.
• Check or replace the anode rod every 2–3 years.
• Test the temperature and pressure relief valve each year.
• Look for rust or leaks.

For tankless water heaters

• Descale or flush once a year (more often if you have hard water).
• Clean air and water filters.
• Keep an eye out for error codes or warning lights.

In Florida’s hard water zones, mineral buildup can happen fast—so stay on top of it.

When Maintenance Isn’t Enough: Signs It’s Time to Replace

• Age: 8–12 years (tank) or 15–20 years (tankless).
• Rusty or discolored hot water
• Weird noises or rumbling.
• Leaks or pooling water.
• Inconsistent hot water.

Time for an Upgrade? Re-Evaluate Your Size and Type

Think about size

Your hot water needs might have changed. More family members, new bathrooms, or busy business operations can all mean your old system is too small. Sizing right avoids hot water shortages and wasted energy.

Consider going tankless

Tankless heaters give you endless hot water and save space, but they cost more upfront and may require system upgrades. Businesses like salons, gyms, or restaurants that need lots of hot water might benefit from multiple units or a commercial setup.

Costs and Efficiency

Newer water heaters are more energy efficient and can help cut down your utility bills. Tankless options are more expensive, but may pay off over time. You might even qualify for rebates or tax breaks.

DIY or Call a Pro?

Flushing your tank can be a good DIY project. But when it comes to anode rods, descaling, or anything involving gas or electrical work—call in a pro.

Permits Matter

In Miami-Dade, Broward, and Palm Beach counties, you need a permit to replace a water heater. This keeps you safe and up to code. Always check local rules or work with a licensed professional.
