What needs to be clarified
Examine thermal conditions, hydraulics and controls together; establish whether the cool zone repeats and whether a technical explanation is possible before opening the floor.
Materials to prepare
- Circuit design, installation photographs and as-built plan
- Manifold, actuator and controller specifications and settings
- Manifold access and a warm-up temperature log
What to compare
Compare temperature patterns with pipes, finishes and furniture. Record supply/return temperatures, available flow readings, controller commands and actuator positions. Repeat observations once conditions stabilize, verify circuit labels against actual rooms, and identify inaccessible floor areas.
Possible outcome of the analysis
An integrated observation plan may support explanations involving finishes, flow or controls; insufficient evidence leads to targeted further measurements and local inspection.
Limits of the conclusions
One thermogram does not reveal a pipe's condition directly. Unstable warm-up, different finishes and furniture-covered areas can limit conclusions about the cool strip.
