Underfloor Heating & Cooling Manifold Systems

Experience Leak-Free Heating - Uponor Manifolds Are the Solution

  • Seamless Radiant Heating

  • Unleash the Power of UFH Manifolds!

Underfloor heating (UFH) manifolds cover all radiant heating and cooling applications

The Uponor underfloor heating manifold range has been developed for the use in all domestic, commercial, and industrial radiant heating and cooling systems.

Our UFH manifold systems provide joint-free pipes that run from a centrally positioned manifold to each radiator valve, tap or water outlet. With joints only at the manifold and the radiator/taps, the risk of leakage is considerably reduced as there are no connections within the walls or floors.

The systems can be designed with one single pipe dimension, making design and installation that much easier.

What Are Underfloor Heating (UFH) Manifold Systems and Why Are They Important?

Underfloor heating (UFH) manifold systems are essential components of radiant heating and cooling applications. They serve as central distribution hubs that deliver warm water to each individual radiator valve, tap, or water outlet in your heating system. 

The significance of UFH manifolds lies in their joint-free design, which significantly reduces the risk of leakage and enhances system reliability. Whether for domestic, commercial, or industrial settings, UFH manifolds ensure efficient and even distribution of warmth, providing enhanced comfort and energy efficiency.

How Do Underfloor Heating (UFH) Manifold Systems Work?

UFH manifolds operate by directing heated water from a heat source, such as a boiler, through a centrally positioned manifold. From there, the warm water flows through joint-free pipes to the radiators or taps in each area of your property.

The precise control and distribution of heat allow for individual ambient temperature adjustments, ensuring optimal comfort in every room. This system's efficiency results in reduced energy consumption and lower heating costs compared to traditional radiator heating methods.

How to Install UFH and Where to Install It

UFH manifolds are typically installed in a central location, conveniently placed to distribute heated water evenly throughout your property. Ideal locations include utility rooms, basements, or dedicated service areas. 

During installation, careful consideration is given to the layout and design of the pipes, ensuring seamless integration into the floor or wall structure. It's essential to plan the system's layout, considering the specific heating needs of each area and the optimal positioning for the manifold to achieve efficient heat distribution.

What are the Essential Manifold Components

A UFH manifold consists of various essential components that work together to ensure smooth operation and efficient heat distribution:

  • Supply and Return Manifolds: These serve as the main distribution points for warm water supply and the return of cooler water back to the heat source.
  • Flow Meters: Optional flow meters provide precise control over the flow rate of water in each circuit, allowing for fine-tuned adjustments.
  • Lock Shield Valves: These valves enable balancing of the system, ensuring that each radiator or tap receives an equal amount of warm water.
  • Loop Connections: Loop connections link the manifold to individual radiators or taps, facilitating the distribution of heat throughout the property.
  • G3/4" Eurocone and G1" Connections: These standardised connections ensure compatibility and ease of installation with other plumbing components.
  • Modular Design: UFH manifolds come in modular designs, allowing for flexibility and adaptability to different heating circuit requirements.
By understanding the importance, functionality, and installation process of UFH manifolds, you can create an efficient and comfortable heating system tailored to your specific needs and preferences.

FAQs Regarding (UFH) manifolds

Q: What types of materials are used to construct underfloor heating manifold systems?
A: Materials such as stainless steel, glass fiber-reinforced polyamide, and brass are commonly used for constructing manifold systems.

Q: How do underfloor heating and cooling manifold systems ensure efficient heat distribution?
A: The manifold systems regulate the flow of water to each loop of pipes, ensuring balanced and even heat distribution across the floor.

Q: Are underfloor heating manifold systems energy-efficient compared to traditional heating methods? 
A: Yes, underfloor heating systems are generally more energy-efficient, as they operate at lower water temperatures, reducing energy consumption.

Q: Do underfloor heating manifold systems support zoned heating and cooling?
A: Yes, these systems can be divided into zones, allowing for independent temperature control in different areas of the building.
