Electric radiant floor heating in renovation

Coordinate electrical load, thermostat/sensor, substrate, membrane, finish and prohibited zones before covering cable or mat.

VERT / GREEN

Keep cable layout/photos and manufacturer-required test values before covering.

JAUNE / YELLOW

Changing finish, adding fixed furniture or drilling later can create overheating zones or damage concealed cable.

ROUGE / RED

Damaged cable, electrical fault, insufficient circuit or undocumented installation before close-in: qualified electrician/installer.

Interactive triage

Helps choose the next step; it does not replace design, permits or professional diagnosis.

Cable layout missing
Photograph and document before covering. Cable/mat damaged
Do not cover; test/repair per manufacturer and code. New thick floor finish
Check thermal limits and finish compatibility. Manufacturer tests archived
Keep test results, sensor and layout with home record.
