Stainless Steel Underfloor Heating Manifold 2 to 12 Port Options

This premium range of stainless steel underfloor heating manifolds is designed to provide efficient distribution, control, and balancing of warm water flow in underfloor heating manifold systems. Heating manifold available with 2 to 12 ports, these pre-assembled manifolds offer flexibility to suit projects of varying sizes — from small residential zones to larger commercial installations.

Each heating manifold assembly features dual manifold bars (flow and return), precision-engineered stainless steel construction for corrosion resistance and durability, and fully integrated components for durable, reliable performance. They are compatible with 12mm and 16mm pipework systems, and designed to meet or exceed BS EN 1264-4 standards and UK building regulations.

What’s Included

• Dual manifold body with 2 to 12 ports (flow and return)
• Lockshield valves with integrated flow meters on all flow ports for individual circuit balancing
• Ball isolation valves fitted with temperature gauges on return ports for temperature monitoring
• Automatic air vents on both flow and return manifolds to purge trapped air
• Drain and fill valves with blanking caps for convenient system filling and maintenance
• Eurocone pipe connectors compatible with 12mm and 16mm multilayer pipes
• Adjustable, corrosion-resistant metal mounting brackets for secure wall or cabinet installation
• Comprehensive installation and balancing guide documentation

Key Features

• Robust high-grade stainless steel construction (typically SUS304) for long-term durability and corrosion resistance
• Pre-assembled plug-and-play manifold system reducing installation time and complexity
• Individual flow meters on all ports with a range commonly 0 to 5 L/min for precise flow balancing
• Integrated temperature gauges for easy manual temperature monitoring and system commissioning
• Automatic air vents ensure optimum system efficiency by removing trapped air
• Valve actuators compatible for upgrade to automated control systems
• Working pressure up to 10 bar (1000 kPa) and temperature rating up to 100°C (some variants up to 105°C)
• Compact and modular design with varying manifold lengths increasing with the number of ports
• Suitable for hot water/glycol mixtures commonly used in underfloor heating
