What it is

The John Guest JGUFHMAN12/3 is a 12-port underfloor heating manifold manufactured by John Guest. It acts as the central distribution point in an underfloor heating system, connecting the heat source pipework to the individual underfloor heating circuits. Each of the twelve ports serves a separate circuit.

Before you order

  • Confirm the port count matches the number of underfloor heating circuits in the installation.
  • Check the manifold against the pipe sizes and connection types used in the system.
  • Verify the part number JGUFHMAN12/3 against the existing manifold or the system documentation.
