Thermographic inspection of underfloor heating shows you where heat flows and where heat loss occurs. We at Ultrices Leak Detection locate groups, loops, manifold, supply, and return lines without any demolition or breaking.
Using IR thermography and a FLIR thermal imaging camera, we measure emissivity and delta T. We detect cold zones, leaks, blockages, air, and defective actuators under tiles, laminate, PVC, concrete, and screed.
You will receive a report with a pipe trace, pressure test, moisture measurement, and advice for efficiency and comfort. View our thermographic inspection underfloor heating reviews, Google reviews 5/5, and schedule your leak detection.

Thermographic inspection of underfloor heating explained
Thermographic inspection of underfloor heating involves mapping heat flows in your floor using an infrared camera so that we can see exactly where pipes run, where heat loss occurs, and where a leak or blockage is located. At Ultrices Leak Detection, we use thermal imaging cameras from brands such as Teledyne, FLIR, Testo, and Optris, and carefully adjust emissivity and reflectivity to the floor surface. The basis comes from the physics of thermal radiation—think of Planck and Stefan-Boltzmann—which make temperature differences visible as high-contrast patterns. This allows us to quickly determine, without any demolition work, whether your underfloor heating performs according to EN 1264 and where things go wrong in water-based or electric systems with a heat pump central heating boiler or district heating.
How underfloor heating thermographic inspection works
We combine thermography with pressure measurement, flow control, and knowledge of floor construction, such as anhydrite-sand-cement dry construction and insulation boards. As a result, the thermal image directly displays the flow direction of loops, the supply and return temperatures, and thermal anomalies such as cold zones or damp spots indicating leakage. Our process follows strict protocols and aligns with ISO 18434 and ASTM C1060 for building envelopes.
- Intake and diagnosisWe discuss issues such as pressure loss in cold zones or a pump that keeps running, and check the manifold and thermostat control.
- Preparing the systemWe set the installation to a stable temperature difference with a correctly set delta T and ensure sufficient flow rate.
- Thermal excitation: we heat or cool in a controlled manner so that pipes and defects stand out clearly in the thermal image.
- Infrared scan: using high-resolution IR cameras, we capture pipe traces, including hotspots, thermal bridges, and suspected moisture.
- Anomaly analysis: we interpret patterns taking into account emissivity, reflections, solar radiation, and floor finishes such as PVC tiles or parquet.
- Additional measurementsIf necessary, we perform a pressure test for underfloor heating leaks or locate them using tracer gas and acoustics for precision.
- Reporting and adviceYou will receive a comprehensive expert report with photos, conclusions, and repair recommendations within three days.

Types of systems and what thermography reveals
- Water-based underfloor heating: shows clear supply and return patterns of imbalance in the distributor and zones with possible air or sludge, causing a decrease in comfort.
- Electric underfloor heating: visualizes defective mats through interrupted heat traces and local hotspots at a cable break.
- Drywall and renovation: makes the thermal resistance of plates and bends visible so that we balance efficiently without demolition.
- Floor finishes: reveals the damping effect of wood and high-gloss tiles, allowing us to still achieve sharp localization using emissivity corrections.
- Source installations: checks whether the heat pump or central heating system and the mixing ratio at the manifold are correct for a stable temperature profile.
Applications for malfunctions and leaks
- Targeted leakage detection: thermal spots and escaping heat patterns reveal the exact leak point, after which a small, targeted repair action suffices.
- Pressure loss and airDeviating supply and return temperatures and irregular patterns indicate air in the loops or a poorly circulating pump.
- Blockage or kink: a suddenly cold section indicates silt or a kink, especially on long loops and poorly balanced distributors.
- Cold zones and comfort complaintsWe resolve inconsistent floor comfort by optimizing hydronic balance and flow rate settings based on the thermal image.
- Moisture and wet insulation: prolonged leakage causes diffuse cold spots due to evaporation and saturated insulation, which we classify thermally and in terms of building physics.

Our measurement method and protocols for reliable results
We work with calibrated FLIR and Testo cameras with high thermal sensitivity and resolution, and we check emissivity with reference tapes. We use measuring tapes, markers, and construction drawing overlays to reconstruct piping diagrams and loop lengths. For reflective tiles, we adjust the angle of incidence and polarization, and we document ambient temperature, relative humidity, and surface conditions. Our specialists are ITC trained and exclusively VCA VOL and NEN 3140 certified, ensuring safety and quality. All findings are included in a report accepted by insurers, including photos, conclusions, and prioritized repair recommendations.

Frequently asked questions
How does thermographic inspection of underfloor heating work and what do you see on the thermal image?
We heat your circuit in a controlled manner and scan the floor with a calibrated thermal imaging camera from, for example, FLIR or Testo. Infrared thermography makes temperature patterns visible, causing pipe routing, cold zones, leakage plumes, air bubbles, and blockages to stand out sharply. We work according to building physics principles from EN 13187 and take emissivity, reflection, and delta T into account.
The images show direct indications, such as a cold streak due to pressure loss or an overheated bend caused by a kink. Substrate and finish also play a role. Tile, PVC, laminate, or parquet requires a different heating strategy for each material. With our 15+ years of practical experience, you interpret the images not only beautifully but, more importantly, correctly for action-oriented repair advice through Ultrices leak detection.
Can thermography exactly locate a leak in my underfloor heating without any demolition work?
Yes. Thermographic leak detection is non-destructive and locates leaks to within a few centimeters in most cases. We combine thermal imaging with pressure measurement, flow control at the manifold, and, where necessary, additional methods such as ultrasonic listening or dye to confirm the exact location. This prevents unnecessary breaking open and limits damage and costs.
At Ultrices Leak Detection, we work with professional detection equipment and a proven protocol compliant with EN 1264 for underfloor heating. Our 99 percent success rate, no cure no pay promise, and 24-hour emergency service give you peace of mind. Need urgent assistance in a bathroom area where damage is mounting quickly?

Which signs indicate a leak or malfunction in underfloor heating and when should you schedule thermography?
Watch out for cold streaks in the floor, uneven heating of zones, bubbling noises caused by air, unexplained pressure loss on the manifold's pressure gauge, damp spots, or a rising energy bill. If you see such symptoms, a thermal imaging inspection is the fastest way to identify the cause and location without demolition work.
Schedule the inspection when we can create a sufficient temperature difference. Ideally, there should be a delta T of 10 to 15 degrees between the supply and the ambient temperature. The contrast is often better in the morning or evening.

What does a thermographic inspection of underfloor heating cost and do you receive an insurance-worthy report?
The price depends on the number of groups, accessibility, floor type, and the purpose of the investigation, such as pipe tracing or targeted leak detection. You will receive a clear quotation within 24 hours, and in urgent cases, we will be on-site within an hour. We work nationwide for private individuals and businesses and charge fairly, with a guarantee of coverage and 100 percent risk-free thanks to our "no solution, no payment" policy.
After the investigation, you will receive a comprehensive expert report within three days, including infrared images, visible light reference photos, measurement data, source analysis, and concrete repair recommendations.
