How to prevent water heater breakdowns this winter

February 10th, 2025

Winter is a critical time for your water heater. A breakdown in freezing temperatures can quickly become a nightmare, depriving your home of hot water when you need it most. Fortunately, you can prevent these inconveniences by adopting a few good maintenance practices. Here are Plomberie Lalonde’s tips to extend the lifespan of your water heater and avoid unpleasant surprises this winter.

Perform annual maintenance

Regular maintenance of your water heater is essential to ensure its proper functioning. It is recommended to call Plomberie Lalonde at least once a year to inspect and clean the unit. This maintenance includes checking the sacrificial anode, which prevents tank corrosion, and the thermostat, which should be properly calibrated to avoid overheating or a lack of hot water. A thorough inspection helps detect signs of deterioration before they become major problems.

Descale your water heater

Over time, limescale deposits can accumulate inside your water heater, reducing their efficiency and increasing energy consumption. Regular descaling is therefore necessary, especially if you live in an area with hard water. To do this, drain the tank and use a diluted white vinegar solution to dissolve the deposits. If you are not comfortable performing this task, Plomberie Lalonde can handle the descaling and ensure your water heater operates at peak efficiency.

Check key components

Certain parts of your water heater should be inspected regularly to prevent malfunctions.

• The safety valve: This component prevents excess pressure inside the tank. Make sure it functions properly by purging it from time to time.
• The electric heating elements or gas burner: These components are essential for heating water efficiently. A worn-out heating element or a clogged burner can cause a sudden breakdown.
• Water heater insulation: A poorly insulated water heater consumes more energy and is more likely to fail. Consider adding an insulation blanket around the tank to improve its efficiency.

Monitor water pressure

Excessive water pressure can damage your water heater and shorten its lifespan. Ideally, the pressure should be between 3 and 5 bars. If it is too high, installing a pressure reducer can prevent premature wear and tears.

Conclusion

Taking care of your water heater during winter helps you avoid unnecessary stress and ensures optimal comfort. By performing annual maintenance, descaling, and monitoring key components, you reduce the risk of breakdowns and extend the lifespan of your unit. Don’t wait for a problem to occur, contact Plomberie Lalonde for preventive maintenance and enjoy a worry-free winter!
