10 Ways to Extend the Lifespan of Your Water Heater!

Ever been jolted by an ice-cold shower when all you wanted was a toasty, relaxing wake-up call? Yeah, not fun. Your water heater, the unsung hero of your cozy home, can quietly keep things running for years—until it doesn’t. So, what can you do to avoid being left in the cold?

At LG Home Comfort, your trusted HVAC experts in Ontario, we’re here to keep your water heater humming along for as long as possible. Let’s dive into 10 tried-and-true tips to extend the lifespan of your water heater. (Bonus: These can prevent your money going down the drain and any cold-shower shockers down the line!)

1. Routine Maintenance Is a Must

We get it. Life is busy, and your water heater probably isn’t top of mind until something goes wrong. But just like your car or your favorite gadget, regular maintenance can keep your water heater working longer and more efficiently. Annual check-ups help spot small problems (like leaks or sediment buildup) before they turn into bigger, pricier disasters.

Here’s a tip: every 6 to 12 months, give your water heater a good flush (more on this below). And if you’re unsure how to perform routine maintenance, don’t hesitate to call your friendly Ontario HVAC pros—us!

2. Flush the Tank Annually

Sediment is a sneaky culprit that can reduce the efficiency and lifespan of your water heater. Minerals like calcium and magnesium (especially in hard water areas, like parts of Ontario) settle at the bottom of the tank, creating a barrier between the burner and the water, making your heater work harder than it should.

How do you deal with this? Flush your water heater’s tank once a year! This simple task can be a game changer. Drain a few gallons of water to clear out the gunk, and you’ll see the difference in how your heater performs. It’s like giving your water heater a spa day!

3. Check (and Replace) the Anode Rod

If you’re thinking, “What in the world is an anode rod?” you’re not alone. It’s a crucial component that protects your tank from rust by attracting rust and corrosion. Over time, though, it corrodes itself (thanks, science!). When it’s about 50% gone, it’s time to replace it—an easy fix that can double the life of your heater.

Tip: Check your anode rod every 2 to 3 years. And don’t worry, it’s a lot less intimidating than it sounds. If you’re not sure how to do it—call us! we’ve got your back.

4. Install a Water Softener if You Have Hard Water

We already mentioned hard water being a troublemaker for your water heater, right? Well, if you live in areas with mineral-rich water, your water heater is at risk of accumulating limescale buildup, which can reduce its lifespan.

The solution? Installing a water softener! They filter out those pesky minerals (like calcium and magnesium), letting only soft water flow through. Think of it as giving your water heater a partner in heavy lifting, taking off the extra load while significantly improving the taste and texture of your water as well as extending the lifespan of your appliances.

5. Insulate Your Water Heater and Pipes

Here’s an energy-efficient move that’ll make your water heater last longer and keep your energy bills in check—insulating both your heater and its pipes. Not only does this help maintain water temperature, but it also reduces the workload on your heater, especially during those frosty Ontario winters.

Want a quick boost to your heater’s performance? Insulating the pipes can bump the water temperature by 2-4 degrees Celsius, keeping your home nice and toasty while extending the durability of your water heater.

6. Add an Expansion Tank

If you have a closed system (where water can’t flow back into the main supply), adding an expansion tank can save your heater from high pressure. You see, water expands when it’s heated, and without somewhere for the extra pressure to go, your water heater’s internal components can get damaged. An expansion tank absorbs that extra pressure, making sure your system doesn’t implode.

Not sure if you need an expansion tank? We’re here to help figure that out for you!

7. Test the Pressure Relief Valve

A pressure relief valve (also called a T&P valve) is a safety feature that prevents your heater from literally exploding when pressure gets too high. Yep, we’re talking potential water-heater-kaboom here.

Test the valve once a year. Simply lift the lever and let out a little water. If it doesn’t close back up right away, it’s time for a replacement. Don’t delay on this one—it’s about more than just longevity; it’s about safety.

8. Give Your Heater a Break with Vacation Mode

Taking a vacation? Your water heater deserves one too! Many modern heaters come with a handy-dandy vacation mode feature, which reduces the water temperature while you’re away. This saves energy and prevents the buildup of sediment while you’re not around.

No vacation mode? No problem! You can manually adjust the temperature to about 50°C (120°F) before you leave.

9. Clear the Area Around Your Heater

Give your water heater some breathing room! Keep the area around the tank free from clutter to ensure it can run efficiently and reduce the risk of fire hazards. Plus, clearing the space helps you easily spot leaks or issues early on.

Think of it like giving your water heater personal space. Nobody likes being crowded, right?

10. Inspect Gas Lines and Electrical Connections

If you have a gas-powered water heater, regularly checking the gas lines is essential for safety and longevity. Rusty, cracked, or leaking gas lines can not only affect your heater’s performance but also pose serious safety risks. For electric heaters, check the electrical connections to make sure everything is working correctly.

We strongly recommend calling in a professional for these inspections (that’s us again!) to ensure everything is in tip-top shape.
