The point to understand
Floor temperature can change with controls, flow and balancing. A cool area alone does not establish that a water-based heating loop is leaking.
Put it into practice
Bring manifold labels and previous heating findings. Describe any pressure loss separately from comfort or temperature concerns.
Keep the limits in view
A suitable loop investigation may use temperature patterns with other checks. Electrical heating and unrelated control work are different services.
