A range of water-based underfloor heating manifolds from 2 to 12 ports. Manifold acts as a central hub for controlling warm water supply to individual zones for the underfloor heating system. Our stainless steel manifolds are supplied with the flowmeters that allow you to configure the flow rate for each circuit to provide optimum heating for each zone, auto-air vents that allow any trapped air in the system to escape and temperature gauges to measure the flow and return temperature to ensure the underfloor heating system is functioning correctly.
