When you’re running a business, hot water isn’t optional — it’s essential. Whether you own a restaurant, manage a gym, or operate a hotel, your commercial water heater plays a major role in daily operations. But like any hardworking piece of equipment, it doesn’t run perfectly forever. Regular maintenance isn’t just a “nice to have” — it’s a must.
If you’re not already maintaining your commercial water heater, you could be setting your business up for unexpected costs, downtime, or even health code violations. Here’s why regular upkeep is crucial and how it protects your bottom line.
Why Maintenance Matters
Commercial water heaters work harder than residential units, often supplying hot water 24/7. Over time, sediment builds up, parts wear down, and efficiency drops. If left unchecked, small issues can turn into major breakdowns — usually at the worst possible time.
Routine maintenance helps you:
Prevent unexpected breakdowns
Increase energy efficiency
Extend the life of your unit
Stay compliant with safety and health regulations
Avoid costly emergency repairs or replacements
The Real Cost of Skipping Maintenance
You might think skipping a scheduled inspection saves money, but it often leads to higher costs in the long run. For example, sediment buildup in the tank forces your commercial water heater to work harder to heat the same amount of water, increasing your utility bills. Over time, that buildup can also corrode the tank from the inside, leading to leaks or full system failure.
And then there’s the cost of downtime. If your water heater goes out in the middle of a busy day, it could mean closing your doors temporarily — or worse, failing a health inspection.
A single missed maintenance visit might save a few bucks now, but it can easily cost thousands later.
What Regular Maintenance Looks Like
Proper maintenance of a commercial water heater isn’t just about flushing the tank. Here’s what a professional service visit usually includes:
Inspection of all components – valves, thermostats, burner assemblies, anode rods, and more.
Tank flushing – to remove sediment buildup that lowers efficiency.
Checking for leaks or corrosion – especially in high-demand systems.
Testing safety controls and temperature settings – to ensure compliance and avoid scalding or bacteria risks.
Evaluating system pressure and flow rates – for consistent hot water delivery.
These small checks can prevent major failures — and extend the life of your equipment by years.
Industry-Specific Risks
Depending on your industry, the impact of a failed commercial water heater could be even more severe.
Restaurants: You can’t operate without hot water. A failed heater could mean shutting down service and disappointing customers.
Gyms & Fitness Centers: Showers without hot water? Not acceptable.
Hotels: One cold shower is all it takes for a guest to leave a bad review.
Healthcare Facilities: Sanitation is non-negotiable, and water temperature matters.
In any of these settings, downtime isn’t just an inconvenience — it’s a liability.
How Often Should Maintenance Be Done?
Most manufacturers, such as Bradford White, recommend professional maintenance at least once a year, but high-demand systems may need check-ups every six months. The right schedule depends on factors like your water usage, water quality, and the age of the unit.
If your business relies heavily on hot water, don’t wait for a problem. Preventative service is always cheaper than emergency repair.

It’s Not Just About Longevity — It’s About Efficiency
A neglected commercial water heater works harder and uses more energy. With energy prices climbing, businesses are feeling the pressure to reduce operating costs. Well-maintained systems heat water faster, use less fuel or electricity, and reduce overall wear on components.
In some cases, regular maintenance alone can lead to 10–20% lower energy bills, which adds up quickly in a commercial setting.
The Bottom Line
When it comes to running a business, you already have a lot on your plate. Your commercial water heater shouldn’t be something you have to worry about. With regular maintenance, you can ensure reliable hot water, avoid expensive breakdowns, and keep your operations running without interruption.
If it’s been a while since your last inspection — or if you’re not sure when it was — now’s the time to schedule service. A small investment in maintenance today could save you thousands tomorrow.
