Underfloor Heating Manifolds
Our underfloor heating manifolds regulate and balance water flow across multiple zones, ensuring your system runs efficiently and evenly.
Whether you’re managing a single-room setup or a complex multi-zone installation, these manifolds deliver consistent results and smooth performance.
Each unit features premium-grade brass construction, pre-fitted flow meters, return valves, isolation ball valves, and automatic air vents. These components make installation quick, reduce maintenance, and allow precise control over every circuit.
We offer configurations from 2 to 12 ports, all with standard ¾” Eurocone outlets. These manifolds suit 16mm and 20mm pipework, making them ideal for both new builds and retrofit systems. Pre-mounted brackets and noise-reducing supports allow for fast, secure fitting to walls or cabinets.
Trusted by installers across the UK, our manifolds combine durability, ease of use, and system compatibility. Choose a component that helps you deliver professional results every time — with fast delivery and full support from our expert team.
