Product Guide
How to Control the Flow Rate
The water flow in your underfloor heating system is managed by the adjustable valves located on each individual manifold loop. This allows for precise temperature control in every room.
Manual Operation Steps
You can easily adjust the settings by turning the handwheel (red or green valve cap) on each port:
Turn Clockwise (Right): Closes the valve to reduce flow rate and lower the temperature in that specific zone.
Turn Counter-Clockwise (Left): Opens the valve to increase flow rate and boost the heating output for that area.
Visual Precision Guide
To ensure accurate adjustment, each valve features a clear visual indicator with red and blue directional arrows. This intuitive design helps users and installers identify the correct rotation path at a glance, preventing errors and ensuring perfect zone balancing.
Parallel Connection: A Modern Alternative to T-Piece Systems
Our manifold system utilizes a parallel connection design, which offers significant performance upgrades over traditional "T-piece" plumbing. By providing dedicated lines to every outlet, we ensure a more stable and reliable water supply.
a. Total Flow Independence
In a parallel system, every water point—such as the toilet, shower, or washbasin—has its own independent supply pipe. This means adjusting the flow rate on one branch will not cause sudden pressure drops or interference in other areas of the building.
b. No More "Water Competition"
We eliminate the common frustration of "water stealing." For example, if someone is washing dishes, the person in the shower won't experience a sudden loss of cold water or a dangerous temperature spike. Each outlet receives a consistent, dedicated flow.
c. Balanced Water Distribution
Our manifold ensures even water distribution across the entire property. This balance not only improves user comfort but also stabilizes internal pressure, significantly reducing the risk of pipe bursts caused by sudden hydraulic shocks.
d. Enhanced System Safety
By centralizing all connections at the manifold, there are fewer hidden joints behind walls or under floors. This leak-proof approach simplifies maintenance and protects the structural integrity of the home.
Technical Standards for Long-term System Stability
To ensure the peak performance and longevity of your HVAC installation, all flow adjustments must adhere to the following technical protocols:
a. Gradual Adjustment (Anti-Water Hammer Protection)
Always rotate the valve handwheels slowly and smoothly. Rapid changes in flow rate can trigger Hydraulic Shock (Water Hammer), causing sudden pressure spikes that stress the pipework. Controlled adjustments protect the structural integrity of the entire system.
b. Operational Pressure Limits
While our manifolds are engineered to withstand a Maximum Working Pressure of 10 Bar, we recommend following standard safety margins during site testing. For routine system pressure tests
c. Media Compatibility & Performance
Our flow adjustment mechanism is precision-engineered for diverse heating fluids. It maintains 100% operational stability in:
Pure Water systems.
Water-Glycol Solutions (up to a 30% concentration).
The internal seals and valves are specifically treated to resist chemical degradation from common UK heating inhibitors and anti-freeze additives.
Ensuring Maximum Hardware Performance
The precision of your flow control depends on the condition of the system hardware. Following these simple maintenance steps will guarantee long-term reliability and accuracy.
a. Routine Flexibility Checks (Anti-Sticking)
To ensure your system is always ready for adjustment or emergency shut-off, we recommend a quick manual check of the valve handwheels once a month. Regularly rotating the knobs prevents mineral buildup and ensures the internal pins never become "stuck," maintaining smooth operational flexibility.
b. Annual System Flushing
At the end of every heating season, a professional system flush is highly recommended. Removing sludge, limescale, and debris protects the precision of the flow meters and balancing valves. A clean system ensures that your flow rate remains within the designed technical range and prevents blockages.
c. Essential Frost Protection
In extreme cold (below 0°C), if the heating system is not in operation, the manifold must be completely drained. Stagnant water can freeze and expand, leading to manifold cracking and permanent damage to the flow control components. Proper drainage is the best way to avoid costly winter repairs.
d. Centralized Water Management
By utilizing our centralized manifold arrangement, property owners can achieve precise hydraulic balancing or execute an emergency shutdown of the entire building’s water system within minutes. This professional-grade engineering ensures efficient, safe, and stress-free water management for any modern project.
Factory Engineering & Design Excellence
A: Precision Engineering & Material Excellence (The XF25289B Series)
Our XF25289B Series is the result of advanced metallurgical standards and precision manufacturing. We distinguish ourselves through two core pillars:
a. High-Grade Forged Nickel-Plated Brass
Unlike standard "cast" alternatives, the main body of our manifold is crafted from high-density forged brass.
Superior Density: The forging process eliminates internal porosities (air bubbles) and structural weak points, ensuring a much higher resistance to pressure.
Anti-Corrosion Finish: Every unit is finished with professional nickel plating, which adds an extra layer of protection against oxidation and chemical treatments commonly found in heating systems.
Maximum Durability: This robust construction allows the manifold to handle a 10 Bar working pressure with a significant safety margin.
b. Premium EPDM Sealing Technology
To ensure a 100% leak-proof system, we utilize EPDM (Ethylene Propylene Diene Monomer) for all internal seals and gaskets.
Thermal Stability: EPDM is specifically chosen for its ability to maintain elasticity under high temperatures (up to 90°C).
Chemical Resistance: It remains stable and does not degrade when exposed to the 30% glycol solutions or chemical inhibitors used in modern hydronic systems.
Long-Term Performance: These seals prevent hardening or cracking over decades of use, guaranteeing consistent sealing stability and lower maintenance costs for the end-user.
A: Professional Commissioning & Pressure Safety Protocols
We strongly recommend conducting a thorough internal pressure test immediately after the pipework has been laid and before the final floor screed is poured. While Sunfly manifolds are engineered for extreme durability, protecting the integrity of the entire system—especially the UFH pipes—is our priority.
Safe Pressure Recommendations
To ensure a secure installation without compromising system longevity, we advise the following:
Optimal Testing Limit: We recommend that the system pressure test should not exceed 0.8 MPa (8 Bar).
Protection of Pipework: Although our manifolds can withstand much higher pressures, 0.8 MPa is the ideal "sweet spot" for detecting leaks while preventing irreversible structural damage or excessive stress on the underfloor heating pipes and connection joints.
System Integrity: This safety margin ensures that the expansion and contraction limits of the polymer pipes are respected, guaranteeing a leak-free foundation for the building's heating infrastructure.
Key Features
Parallel Distribution: Stability & Security
Our manifold system employs a parallel connection design, providing a superior alternative to traditional plumbing. By centralizing water distribution, we enhance both daily comfort and long-term safety.
Dedicated Branch Independence
Every water outlet—including toilets, washbasins, and showers—is supplied by a dedicated pipe directly from the manifold. This individual piping ensures that each branch operates independently.
The Benefit: No more "water competition." For example, someone can wash dishes in the kitchen without causing a sudden temperature drop or loss of cold water for someone else in the shower.
Balanced Flow & Burst Protection
The parallel layout guarantees even water distribution across the entire property. By stabilizing internal pressure and reducing hydraulic surges, this design significantly minimizes the risk of pipe bursts, ensuring the structural integrity of the plumbing system for decades.
Centralized Emergency Control
All critical engineering valves are arranged in one centralized location. This ergonomic layout allows users or maintenance teams to identify and perform an emergency shut-off for any specific zone—or the entire building—within minutes. This quick-response capability is a vital safety feature for modern high-end residential projects.
