What to Do When Your Commercial Heater Stops Working

A broken commercial heating system can quickly escalate from a minor inconvenience to a serious problem. Whether you’re running a busy warehouse, workshop, or any commercial space, a lack of heating affects not just employee comfort, but sometimes compliance too.

At Combat, we understand how frustrating unexpected heating issues can be. In this practical guide, we’ll teach you to respond quickly and get your system back up and running.

1. Check the Basics

It might sound obvious, but start with the simplest checks. Ask yourself:

• Is there power to the system? Has a circuit tripped?
• Are any emergency stop buttons activated?
• Have time clocks or thermostats been adjusted recently?

Sometimes the issue isn’t with the heater itself but with the settings or supply, and if that’s the case, it’s an easy 5-minute fix!

2. Identify the Problem

If it’s not something simple, try to pinpoint any obvious faults.

• Are there warning lights or fault codes displayed?
• Are there strange noises, smells, or visible damage?

Take note of any error codes and cross reference these with your Combat manual. This information can help our engineers diagnose the problem faster and get the issue resolved.

Never attempt to open or repair heating equipment yourself unless you’re qualified to do so. It’s not just risky, it could invalidate your warranty or insurance too.

3. Contact Us

If a reset hasn’t solved the issue, it’s time to call an engineer. At Combat, our team specialises in diagnosing and repairing the commercial heating systems that we design and install.

We’ll provide clear advice, quickly, and can offer reliable repairs to get you back up and running with minimal disruption.

4. Plan for the Future

One breakdown is frustrating but repeated breakdowns are a sign it’s time to take a closer look at your heating system. Make sure to implement regular maintenance to extend the lifespan of your equipment - this can be as simple as regular cleaning and a pre-winter check up once per year.

5. Consider an Upgrade

If breakdowns are becoming more frequent or your system is outdated, it might be time to think about upgrading. Modern heating solutions are more efficient, more controllable, and more cost-effective to run.

We can help you assess whether a repair, replacement, or upgrade makes the most sense for your business.
