Do I Need a Manifold for Underfloor Heating?

What is an underfloor heating manifold?

An underfloor heating (UFH) manifold is the central hub that distributes warm water to different circuits of a hydronic UFH system. It ensures balanced water flow and temperature control across different heating zones.

Is a manifold necessary for water underfloor heating?

Yes, a manifold is essential for wet underfloor heating systems. It regulates water distribution, ensures even heating, and allows independent control of each zone. Without a manifold, balancing the system would be extremely difficult, leading to inefficiencies.

Can I install underfloor heating without a manifold?

Technically, you could install a very basic system without one, but it would lack efficiency, precise control, and even heat distribution. In nearly all UK installations, a manifold is a must-have.

What type of manifolds are available?

• Standard manifolds: Simple distribution units with manual flow controls.
• Thermostatic manifolds: Offer automatic flow regulation for better efficiency.
• Pre-assembled pump and manifold kits: Include integrated pumps for simplified installation.

How do I choose the right manifold?

Factors to consider:

• Size – Based on the number of heating zones.
• Material – Nickel Plated Brass offers the best combination of durability and Energy Saving.
• Control options – Manual or automatic balancing.
• Flow meters – Help monitor system performance.
