Leak detection using aerial thermal imaging
Aerial thermal imaging is a method used to detect leaks in district heating networks by measuring heat radiation from the air using advanced thermal imaging cameras. Depending on the size and conditions of the area, we conduct inspections using either drones or aircraft.
The technology makes it possible to quickly identify temperature anomalies that reveal hidden leaks. The result is a clear overview of the condition of the network, helping you plan maintenance measures, reduce energy losses, and avoid costly downtime.
AI-driven analysis for
safer leak detection
We use machine learning to analyze the thermal images collected during aerial thermal inspections of district heating networks. By using AI, the system can quickly identify patterns and temperature anomalies that indicate leaks with greater accuracy than manual interpretation.
The AI helps us distinguish actual leaks from natural heat sources, saving time and providing a more reliable basis for decision-making. The result is faster reporting, fewer false positives, and more dependable leak detection using drones or aircraft.
Aerial thermal imaging – step by step
1
Quotation
We review your request and provide a cost estimate based on the size of the network, the area to be inspected, and the preferred inspection method.
2
Meeting
We review the scope of the project, potential challenges, and site conditions. Flight planning, scheduling, and communication procedures are established at this stage.
3
Flight operation
We carry out the flight under suitable weather conditions. The inspection is conducted at night using a high-resolution thermal imaging camera.
4
Delivery
You receive a detailed report including suspected leaks, map visuals, and a review of the results in our proprietary software.
Efficient leak detection with
aerial thermal imaging
High precision
With aerial thermal imaging, we can detect leaks at an early stage using thermal imaging cameras in environments ranging from densely populated areas to challenging terrain.
Fast and large-scale
Aerial thermal imaging enables efficient inspection of large areas in a short amount of time, with rapid analysis supported by AI.
Detailed results
You receive a visual report with thermal images that make it easy to identify and prioritize potential leaks, along with advanced software designed to detect changes and support the leak detection process.

Niklas Robledo is responsible for our aerial thermal imaging services. Schedule a meeting to discuss opportunities, project setup, and the conditions for leak detection in your district heating network. Niklas will help you find the solution and method best suited to your specific needs.
The price varies depending on the size of the network, the inspection method (drone or aircraft), and the geographical conditions of the area. Contact us for a quotation.
Drone-based aerial thermal imaging provides very high resolution and can detect even small leaks, especially in urban areas and smaller networks.
Flights are best carried out during cold, clear nights in autumn, winter, or early spring, when heat leakage is most visible in thermal images.
Reports, map data, and software access are typically delivered within 1–2 weeks after the completed flight operation.
