Prime Design Underfloor Heating Manifold Set

Prime Design Stainless Steel Underfloor Heating Manifold Set

Designed for the efficient distribution, isolation, and hydraulic balancing of warm water underfloor heating systems, this manifold complies with BS EN 1264-4. Each heating circuit’s flow rate can be precisely adjusted between 1 and 5 litres per minute using the integrated flow meters on the upper flow manifold. Individual circuits can be manually isolated using the shut-off caps on the lower return manifold.

Key Features

• Universal M30 × 1.5 Valve Connection – Compatible with standard thermal actuators.

• Precise Flow Rate Control – Enables accurate circuit balancing and reliable flow adjustment, including at higher flow rates.

• Premium EPDM O-Ring Seals – Provide effective sealing, smooth operation, and long-term reliability.

• 1″ Male Flat-Sealing Connections – Ensure secure and dependable connections to the heat source.

• 3/4″ Eurocone Circuit Connections – Allow straightforward installation using compatible compression fittings.

• Integrated Filling and Flushing Assembly – Includes a 3/4″ swivel connection to facilitate system filling, draining, flushing, and isolation.

• Pre-Fitted Wall-Mounting Bracket – Supplied with low-noise pipe clamps designed to meet DIN 4109 acoustic requirements, supporting quiet operation and convenient integration with pump groups, hydraulic control units, heat interface units, and other compatible heating equipment.

Package Contents

• Upper flow manifold with integrated flow meters.

• Lower return manifold with removable manual isolation caps.

• Integrated filling valve and automatic air vent.

• Integrated drain valve and pressure gauge.

• Pre-fitted mounting bracket with low-noise pipe clamps.
