Underfloor Heating Manifold Pump Kit with Mixing Valve

Stainless Steel Underfloor Heating Manifolds

Our Stainless Steel Underfloor Heating Manifolds provide the central distribution point for water-based underfloor heating systems. Available in three manifold types and configurations from 2 to 12 ports, the range can accommodate systems of different sizes and numbers of heating zones.

The manifold receives warm water from a compatible heat source, such as a boiler or heat pump, and distributes it through the individual pipe circuits installed beneath the floor. Once the water has travelled through each circuit, the cooler return water flows back through the manifold and is directed to the heat source for reheating.

Integrated flow meters provide clear visibility of the water flow through each circuit and allow the system to be balanced for consistent heating. When combined with compatible thermostats and actuators, the manifold also enables individual rooms or zones to be controlled according to their heating requirements.

Key Benefits

• Central distribution point for hydronic underfloor heating systems
• Durable stainless steel construction
• Available in three manifold types
• Options available from 2 to 12 ports
• Suitable for systems with multiple rooms or heating zones
• Integrated flow meters for clear flow-rate visibility
• Allows individual circuits to be balanced
• Supports room-by-room temperature control
• Compatible with suitable thermostats and actuators
• Helps maintain consistent and efficient heat distribution
• Suitable for boilers and heat pumps when installed as part of a compatible system

How It Works

1. Warm water enters the manifold from the boiler, heat pump or other compatible heat source.
2. The manifold distributes the water across the connected underfloor heating circuits.
3. Flow meters allow each circuit to be adjusted and balanced according to its requirements.
4. Thermostats and actuators can regulate individual circuits for zoned temperature control.
5. Cooler return water travels back to the manifold before being sent to the heat source for reheating.

Typical Applications

• Residential underfloor heating systems
• Commercial heating installations
• Multi-room and multi-zone systems
• New-build properties
• Renovation and retrofit projects
• Boiler-fed underfloor heating
• Heat-pump underfloor heating systems

Available Configurations

Please note: The correct manifold size should be selected according to the number of underfloor heating circuits rather than the number of rooms alone. System design, compatibility, commissioning and pressure testing should be completed by a suitably qualified installer.
