Manifolds & Mixing Units

Essential Components of Underfloor Heating Systems

Underfloor heating manifolds are pivotal components within the heating system, responsible for controlling and distributing the heated water that circulates through the underfloor pipes. These manifold systems act as centralized hubs, regulating the flow and temperature of the water to ensure consistent warmth throughout the designated spaces. Being the heart of the system, it is crucial to have a top-of-the-line manifold in place, and the Tio manifold is indicative of just that.

Manifolds & Pump Sets

Tio’s premium 304 stainless steel manifold is a pre assembled unit designed for use in underfloor heating and wall hung radiator systems. Supplied complete with an auto air vent, pressure gauge, flow meters and fill and drain valves, it provides accurate control and straightforward long term maintenance. Compatible with pipe sizes up to 20mm.

Pump sets and mixing units play a vital role in underfloor heating systems, ensuring water is circulated evenly and efficiently throughout the pipe network. By maintaining consistent flow and pressure, they help deliver stable temperatures across the floor while supporting system performance and energy efficiency.

Mixing Unit

The mixing unit regulates the temperature of water entering the underfloor heating loops by blending hot water from the heat source with cooler return water. As underfloor systems operate at much lower temperatures than traditional radiators, this process ensures safe, comfortable heat delivery while protecting flooring materials and improving overall efficiency.

When combined with the pump set, the mixing unit forms the control hub of the system. Together, they maintain the correct temperature and flow rate, delivering stable room conditions while safeguarding both the heating system and building fabric.
