HVAC technicians who work around the clock!

Hot water is essential to keeping your business operations running smoothly, whether you’re managing a restaurant, hotel, or industrial facility. A failing water heater can disrupt workflows, escalate costs, and create unnecessary downtime. At LG Mechanical, we specialize in reliable HVAC solutions for commercial settings, ensuring your systems are always operating at peak performance.

Let’s explore 10 proven strategies to extend the lifespan of your commercial water heater—saving your business both time and money.

1. Prioritize Routine Maintenance

Your commercial water heater works hard to meet the high demand of your business. Regular maintenance is critical to identifying potential issues before they escalate. Schedule annual professional inspections to check for sediment buildup, leaks, or wear-and-tear.

Pro tip: Ensure your maintenance partner is an experienced HVAC provider, like LG Mechanical, to safeguard the efficiency of your water heating systems.

2. Flush the Tank Regularly

Hard water is common in many commercial areas, contributing to sediment accumulation in water heaters. Minerals such as calcium and magnesium form deposits, reducing the heater’s efficiency and lifespan. A commercial water heater should be flushed quarterly or semi-annually, depending on usage.

This proactive measure prevents clogs, enhances performance, and ensures your system can handle the heavy lifting required in a commercial setting.

3. Replace the Anode Rod

An often-overlooked component, the anode rod protects your tank from corrosion. In high-demand environments, this rod can wear out faster than expected. Replacing the anode rod every 2-3 years can significantly extend your system’s operational life.

If corrosion has already begun, call LG Mechanical—our experts will assess the damage and recommend cost-effective solutions.

4. Install a Water Softener for Hard Water Areas

For businesses in regions with hard water, a water softener is more than a convenience—it’s a necessity. Softened water minimizes limescale buildup, reducing strain on your water heater and other plumbing systems.

With less mineral residue in your equipment, you’ll experience fewer repairs and longer-lasting appliances, allowing your business to operate more efficiently.

5. Insulate the Heater and Pipes

Energy efficiency matters in commercial operations. Insulating your water heater and its pipes minimizes heat loss and prevents your system from overworking. This small investment can yield big returns by lowering energy bills and extending your heater’s lifespan.

For facilities in colder climates, insulation is particularly crucial. Consult LG Mechanical to install industry-standard insulation for your water heating systems.

6. Use an Expansion Tank

When water expands under heat, pressure increases inside the tank. In commercial systems, this pressure can damage internal components if not properly managed. Adding an expansion tank absorbs excess pressure, ensuring the longevity and safety of your system.

Not sure if your business needs an expansion tank? Our technicians can evaluate your setup and recommend the best solution.

7. Test the Pressure Relief Valve Annually

The pressure relief valve (T&P valve) is vital for safety in any water heater system. In commercial settings, where water usage is higher, a faulty valve poses significant risks. Test it annually to ensure it releases pressure effectively.

If you’re unsure how to test this feature, leave it to LG Mechanical—we’ll ensure your system meets safety standards.

8. Use Energy-Saving Modes During Off-Peak Hours

Commercial water heaters often include energy-saving features designed for businesses with fluctuating demand. Use these settings during non-operational hours to reduce strain and energy costs.

If your system doesn’t have these features, manually lowering the temperature during downtime is an effective alternative.

Commercial water heaters in Ontario often include energy-saving features designed for businesses with fluctuating demand. Use these settings during non-operational hours to reduce strain and energy costs.

If your system doesn’t have these features, manually lowering the temperature during downtime is an effective alternative.

9. Keep the Area Around the Heater Clear

A clutter-free environment around your water heater ensures optimal airflow and reduces fire hazards. In commercial buildings, keeping the surrounding space clear also allows for easier maintenance and faster troubleshooting.

Make this a routine check to prevent unnecessary interruptions to your operations.

10. Inspect Gas Lines and Electrical Connections

Commercial water heaters rely on either gas or electricity. Damaged gas lines or faulty electrical connections can compromise performance and safety. Schedule regular inspections by certified technicians to address issues before they become costly emergencies.
