In residential projects Nu-Heat supplies Alupex-18™ to link the flow and return Fastfit™ distributors to the main Optiflo™ manifolds. It incorporates an integral aluminium core as the oxygen proof layer, so it can be shaped by hand, with no joints or soldering.

Alupex-18™ meets all relevant European standards and is manufactured in the EEC to DIN 4726.

Alupex-18™ is also used in very large commercial/industrial underfloor heating projects.
