Thermal Imaging in Facilities Maintenance

Early fault detection is fundamental to maintaining any building and its systems. One of the most effective, non-destructive tools for spotting hidden issues is thermal imaging. By detecting temperature changes in equipment, pipework, and building structures, thermal imaging allows facilities teams to identify faults before they become a serious issue.  

What is Predictive Maintenance? 

Predictive maintenance uses thermal cameras to monitor equipment's heat signatures, allowing early detection of potential issues before major failures occur. This allows repairs to be scheduled earlier, reducing disruption and avoiding emergency callouts.  

Unlike routine maintenance, predictive maintenance is based on real-time data, which means you only take action when it's needed. This saves time and money and helps prevent bigger issues later on. 

How Thermal Imaging Works 

Thermal imaging cameras detect heat and show it visually, highlighting areas where temperatures are higher or lower than normal. These temperature differences often point to problems like overheating machinery, electrical faults, insulation gaps or leaks that wouldn't be visible otherwise.  

At Thermascan, our trained engineers carry out detailed thermal imaging surveys using advanced FLIR cameras. We analyse the images to identify faults and advise you on the best next steps.  

This approach makes it easier to: 

  • Spot faults early and fix them before they cause failure 

  • Plan maintenance during scheduled downtime, not in emergencies 

  • Improve safety by reducing the risk of equipment overheating or failing 

  • Avoid energy waste by insulation or heating issues 

  • Protect your equipment and extend its working life

Where Thermal Imaging Can Help 

Thermal imaging supports issues that create heat before they cause failure. Thermal imaging can detect:  

Electrical Systems 

  • Loose or damaged connections 

  • Overloaded circuits 

  • Worn components in fuse boxes or switchboards 

Catching these early can prevent power outages, equipment failure or even fire risks. 

Mechanical Systems 

In factories, offices or commercial buildings, thermal imaging helps identify: 

  • Overheating motors or bearings 

  • Misaligned machinery 

  • Lack of lubrication 

These issues can reduce performance or cause breakdowns if not fixed quickly.  

Plumbing and Heating 

Thermal cameras can be useful for finding hidden problems in plumbing systems, including: 

  • Leaks in pipes or valves 

  • Blocked or inefficient radiators 

  • Underfloor heating faults 

They help locate the exact area to fix, reducing disruption and saving time.  

Building Inspections 

Thermal imaging is ideal for checking the condition of a building, especially for: 

  • Heat loss through poor insulation 

  • Air leaks in windows or doors 

  • Damp or moisture problems 

  • Flat roof leaks  

Bold Iine thickness helps spot issues without damaging walls or ceilings, making it quicker and easier to maintain the building's performance.

what to expect from a Thermascan Survey 

We aim to make the process simple and straightforward, whether you're managing a large commercial site or a single property.  

  • Site planning – We communicate with all our clients in advance to understand your needs. In some cases, we might even arrange a pre-visit to plan the best approach. 

  • Risk and method statements – Before getting started, we will provide a clear explanation of the process, including a site-specific risk assessment. 

  • High-quality thermal and digital images – Our reports include clear, accurate visuals that make it easy to understand any faults as we use the most up to date infrared cameras from FLIR.  

  • Engineer insights and recommendations – You'll receive a full report with findings from our certified engineers, including practical advice on what to do next.  

  • Thermal trend reporting – If you choose regular surveys, we'll track changes over time to help you make better maintenance decisions.
