What commissioning records matter for underfloor heating systems?

Why commissioning counts

Underfloor heating changes how a building responds to heat input. Buyers may worry about leaks, floor coverings, and maximum floor temperatures.

What to keep

Flow temperature limits and manifold settings: as left by the installer.

Pressure test evidence: for wet systems after install.

Floor covering limits: manufacturer limits for carpets or vinyl above the system.

Service history: any flush, inhibitor top-up, or repair notes.

Store photos of manifold locations to speed up surveys.
