District Energy & Buried Heat Loop Survey by drone.

Buried hot-water and steam distribution mapped by thermal drone — line losses, failed insulation, and active leaks on district energy systems, hospital and university campuses, found from the air in a single evening flight.

How the investigation runs

  1. 1

    Network mapping

    Routing drawings and operating temperatures define the loop. Where drawings are stale, the first flight itself recovers the true alignment — buried hot lines trace themselves thermally.

  2. 2

    Contrast-window flight

    Flown on cool evenings when the ground has shed solar gain: supply and return lines appear as clean linear signatures, and anomalies — hot spots, plumes, lateral spread — stand out against them.

  3. 3

    Anomaly classification

    Uniform warmth is normal line loss. Localised intensity, asymmetric spread, or surface wetness signatures are classified as insulation failure or active leakage and ranked by severity.

  4. 4

    Dig-sheet report

    Each actionable anomaly delivered with RTK coordinates, thermal evidence, and severity ranking — the document your mechanical contractor digs from, first time, right spot.

Aerial screening + ground confirmation, one company

The aerial survey ranks where the problems are; Leak.ca's ground crews — the same team pinpointing BC leaks since 1999 — confirm them with acoustic correlation, moisture probing, and flood testing where the finding warrants it. One accountable report from first flight to repair-ready coordinates, instead of two vendors pointing at each other.

Frequently asked

How well does thermal imaging work on buried heating lines?

It is the single best application of aerial thermography on buried utilities. A line running 60–120 °C under a metre of soil produces a clear, continuous surface signature in the right window — and a breach or failed insulation section produces an unmistakable local intensification. We routinely recover the routing of loops whose drawings were lost decades ago, then rank every anomaly along them.

What does a leak cost a district energy operator compared to this survey?

A buried heat-loop leak wastes treated, chemically dosed, heated water continuously — energy, make-up water, and treatment, around the clock. Operators typically find a single confirmed leak repays the survey many times over within a season, before counting the avoided excavation of wrong-spot exploratory digs.

When should campuses fly this survey?

Late fall through early spring, on cool, dry evenings — peak season for both thermal contrast and heating load. An annual flight in the same conditions builds a year-over-year baseline, so the question shifts from 'do we have leaks?' to 'what changed since last year?' — the cheapest maintenance posture there is.

Can you also check our buildings while you're flying?

Efficiently, yes — campus surveys commonly bundle the heat loop with roof moisture screening and envelope passes on priority buildings in the same mobilisation. One flight program, several maintenance answers. Ask for the campus bundle when you call.
