1. Recognize the Importance of Prompt Water Heater Maintenance and Troubleshooting

Commercial water heaters work much harder than residential ones, serving multiple outlets and often operating continuously. With increased usage comes a greater need for maintenance and prompt troubleshooting. Recognizing signs of issues early and acting fast can prevent costly repairs and downtime.

a. Prevent Service Interruptions

A faulty water heater can interrupt business operations, impacting everything from customer comfort to cleaning processes. Troubleshooting and repairing issues promptly ensures continuous access to hot water.

b. Minimize Energy Costs

A malfunctioning water heater may consume more energy, increasing operating costs. Addressing issues can improve efficiency and reduce monthly energy bills.

c. Extend Water Heater Lifespan

Regular troubleshooting and maintenance help prevent wear and tear on the system, extending its lifespan and delaying the need for a costly replacement.

2. Identify Common Water Heater Problems

Understanding the symptoms of common water heater problems is the first step in troubleshooting. Each symptom can indicate specific issues within the system, making it easier to pinpoint the problem and take corrective action.

a. Inconsistent Water Temperature

If water temperature fluctuates or fails to reach the desired level, the thermostat or heating element may be at fault. Inconsistent temperature can result from a faulty thermostat, sediment buildup, or a malfunctioning heating element.

b. No Hot Water

When the heater provides no hot water, the problem could be related to the power supply, thermostat, or a failed heating element. For gas water heaters, check the pilot light and gas supply.

c. Unusual Noises

Banging, rumbling, or popping noises are typically caused by sediment buildup in the tank. As sediment heats and cools, it can cause these sounds, indicating that the tank may need flushing or descaling.

d. Leaking Water Heater

A leaking water heater can result from loose connections, a faulty valve, or tank corrosion. Addressing leaks promptly prevents water damage and further complications.

e. Discolored or Foul-Smelling Water

Rusty or foul-smelling water can indicate corrosion inside the tank or issues with the anode rod. Discolored water may also signify sediment buildup or bacterial growth in the tank.

3. Troubleshoot Water Heater Problems Before Calling a Plumber

There are basic troubleshooting steps that building maintenance personnel can try before calling a commercial plumber. While these steps are helpful, contacting a professional is often the best solution for persistent issues.

a. Check the Power Source

For electric water heaters, ensure the power supply is connected and the circuit breaker is on. For gas heaters, confirm that the gas valve is open and the pilot light is lit.

b. Inspect the Thermostat and Temperature Setting

The thermostat controls water temperature, so if the water is too hot or cold, adjusting the thermostat may solve the problem. Ensure the thermostat setting is between 120-140 degrees Fahrenheit.

c. Flush the Tank to Remove Sediment

Sediment buildup can reduce water heater efficiency and cause noise. Flushing the tank involves draining the water to remove any accumulated sediment. This process improves efficiency and extends the water heater’s lifespan.

d. Examine the Anode Rod

The anode rod prevents tank corrosion by attracting corrosive elements. If the rod is worn out, replacing it can prevent rusting and extend the water heater's life. An anode rod should be checked annually and replaced every 3-5 years.

4. Call a Commercial Plumber for Complex Issues

Some water heater issues are too complex or hazardous to resolve without professional help. A licensed commercial plumber has the expertise and tools to address these issues effectively and safely.

a. Diagnose Electrical Issues

Electric water heaters rely on proper wiring and voltage. A commercial plumber or electrician can check for any wiring issues, power supply problems, or faulty elements that may prevent the heater from functioning correctly.

b. Repair or Replace Heating Elements

Heating elements wear out over time, especially in high-demand commercial environments. A plumber can test and replace faulty heating elements, restoring the heater’s ability to produce hot water efficiently.

c. Fix Gas Supply Issues

Gas water heaters require a constant, safe gas supply. A commercial plumber can inspect the gas line, pilot light, and valves, addressing any issues that may disrupt gas flow or cause safety hazards.

d. Address Corrosion and Scale Buildup

If corrosion or scaling is affecting the water heater, a plumber can perform descaling treatments, replace corroded components, and recommend water treatment solutions to reduce future scaling.

5. Consider Upgrading the Water Heater System

If the water heater consistently fails or struggles to meet demand, it may be time for an upgrade. Commercial water heater upgrades can improve efficiency, meet higher demands, and offer greater reliability. Here’s how a plumber can help with upgrading the system.

a. Assess the Building’s Hot Water Demand

A commercial plumber can assess hot water usage to recommend the appropriate heater size and type. Upgrading to a larger or more advanced water heater ensures consistent hot water availability.

b. Consider Energy-Efficient Models

Modern water heaters offer greater energy efficiency. Upgrading to an energy-efficient model, such as a tankless water heater or a high-efficiency gas heater, can reduce energy bills while meeting commercial demands.

c. Explore Tankless Water Heaters

Tankless water heaters provide hot water on demand, which can be ideal for businesses with fluctuating hot water needs. These heaters are energy-efficient, space-saving, and reduce the risk of tank-related issues.

d. Consult on Smart Technology Upgrades

Smart water heaters with built-in sensors and Wi-Fi connectivity allow remote monitoring and temperature control. A plumber can advise on the best smart water heater options to improve efficiency and enable proactive maintenance.

6. Schedule Regular Water Heater Maintenance with a Plumber

Routine maintenance is essential to keep a commercial water heater operating efficiently and prevent unexpected breakdowns. Partnering with a professional plumber, such as ADS Wales, for routine maintenance can help extend the system's lifespan.

a. Annual Inspection and Cleaning

Annual maintenance, including an inspection and thorough cleaning, helps identify minor issues before they become major problems. A plumber will check components such as the thermostat, heating elements, and tank for signs of wear.

b. Flushing the Tank

Flushing the water heater tank annually removes sediment buildup, improves heating efficiency, and reduces wear on heating elements. Regular flushing is especially important in areas with hard water.

c. Check and Replace the Anode Rod

Inspecting the anode rod during maintenance and replacing it as needed prevents tank corrosion, helping to extend the water heater's lifespan. A professional plumber can ensure the rod is replaced correctly.

d. Monitor and Adjust Temperature Settings

During maintenance, a plumber can check the thermostat settings to ensure they meet the building’s hot water needs without wasting energy. Proper temperature settings reduce wear and enhance performance.

7. Recognize When Replacement is Necessary

While maintenance and repairs are often sufficient, some water heater issues indicate that replacement may be the best option. Working with a commercial plumber ensures that you select the right replacement model and that installation is completed safely and efficiently.

a. Frequent Repairs and High Maintenance Costs

If the water heater requires frequent repairs or maintenance, replacement can be a cost-effective solution. Modern water heaters are often more energy-efficient and reliable, reducing long-term costs.

b. Aging Water Heater (10+ Years)

Commercial water heaters typically last 10-15 years. If the heater is nearing this age, replacing it proactively can avoid breakdowns and provide a more efficient, reliable hot water supply.

c. Inability to Meet Hot Water Demand

If the water heater consistently fails to meet demand despite troubleshooting, an upgrade to a larger or more efficient model may be necessary to accommodate the building’s needs.

d. Visible Signs of Corrosion and Leaks

Corrosion on the tank or significant leaks often indicate that the water heater is beyond repair. A commercial plumber can help select a suitable replacement that meets both hot water and energy-efficiency requirements.
