The UFH pipe is connected via a dedicated EuroCone adaptor (either push-fit or compression type depending on the adaptor chosen), which threads onto the manifold port. It is a very secure connection suited to permanent installations, and is the preferred connection method in professional UFH systems. It differs from push-fit in that the adaptor engages with the male thread before the pipe is pushed in — providing a more robust and auditable connection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003ch3\u003eCan I use this manifold with 12mm Overlay pipe?\u003c\/h3\u003e\n\u003cp\u003eYes, but you will need to purchase UFH12EC EuroCone adaptor packs separately. Each pack contains 2 adaptors, so you need one pack per port (e.g. a 4-port manifold needs 2 packs of UFH12EC). The adaptors fit onto the G¾\" port and convert the connection to accept 12mm pipe as used in the Polypipe Overlay and Overlay Lite systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003ch3\u003eDo I need a larger manifold if I have a larger room?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily — the port count is determined by the number of separate pipe circuits, not room size. A single large room may require two or more pipe circuits (and therefore two or more ports) depending on the floor area, pipe spacing, and design heat loss. Conversely, a small room may be served by a single circuit on a single port. Always base port count on your UFH system design plan, not on room count alone.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003ch3\u003eWhy does this manifold not come with isolation valves?\u003c\/h3\u003e\n\u003cp\u003eIsolation valves for the supply connections are sold and specified separately because there are different valve types suitable for different installation configurations (e.g. with or without a blending valve unit, with or without a pump). Polypipe supply a range of compatible isolation valve assemblies and pump\/blending stations to suit different system designs, and including one type as standard would not suit all installations. Your UFH installer or system designer will specify the correct valve assembly for your configuration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003ch3\u003eCan two smaller manifolds be used instead of one large one?\u003c\/h3\u003e\n\u003cp\u003eYes — in larger systems it is common practice to use two manifolds in different locations (e.g. one manifold per floor of a property) rather than running all circuits to a single central manifold. This reduces pipe run lengths and is often more practical.

Central heating systems run at 70–80°C; underfloor heating requires water at 30–60°C maximum, with many systems operating most efficiently at 35–45°C for the majority of the heating season. Without temperature regulation, excessively hot water running through underfloor circuits can damage flooring, cause discomfort, and waste energy.\u003c\/p\u003e\n  \u003cp\u003eThe manifold control pack is the device that blends boiler-temperature water with cooler return water from the circuits — using the UFCH mixing valve — to produce the correct flow temperature for the underfloor system.

Vent the pump and manifold circuits thoroughly before energising. Set the mixing valve to the lowest temperature initially and increase in 5°C increments over the first few days of operation when commissioning solid floor systems — this allows screeded floors to warm up gradually without cracking. For other floor types, set the mixing valve to the system design temperature directly.\u003c\/p\u003e\n\n  \u003cdiv class=\"pp-callout\"\u003e\n    \u003ch3\u003e💡 Commissioning Tip — Solid Floors\u003c\/h3\u003e\n    \u003cp\u003eIf commissioning a solid floor (screeded) system, do not run the system at full temperature immediately.

While the Clip Rail uses separate rails to position the pipe, the Red Panel provides a complete pre-formed grid that the pipe is guided through directly. The castellated knobs in the panel surface grip and hold the pipe at the pre-determined spacing, eliminating the need for separate clips, measuring, or chalked guidelines. The result is faster, more consistent pipe spacing — particularly beneficial for spiral (snail) configurations where precise, even spacing is important for uniform heat distribution.\u003c\/p\u003e\n  \u003cp\u003eA key performance advantage of the red panel system is that the castellated surface lifts the pipe slightly above the insulation boards beneath. This allows screed to flow underneath the pipe as well as above it, fully enveloping the pipe in the screed mass. Full pipe encapsulation improves heat transfer between the heated water and the screed, and increases the thermal mass effect of the system. Additionally, once screeded, the panels displace approximately 15% of the screed volume, slightly reducing the amount of screed material needed.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n  \u003cdiv class=\"pp-grid\"\u003e\n    \u003cdiv class=\"pp-card\"\u003e\n\u003cstrong\u003e🔴 Precise Pipe Positioning — No Measuring\u003c\/strong\u003eCastellated knobs guide and grip pipe at 100mm, 200mm, or 300mm centres automatically.

Lay the first red floor panel with the ½-castellation edge against the wall. Interlock subsequent panels — the ½-castellation of each panel overlaps the ¾-castellation of the previous. Continue to fill the room, cutting panels to fit at perimeter edges and around obstacles. Fit edge expansion strip around the room perimeter before laying pipe — this accommodates thermal expansion of the screed. Lay pipe from the outside of the coil, unrolling in the direction of travel. For spiral configurations, route the pipe through the castellations at the required spacing, using two castellations for a 90° bend and three for a 180°. Secure at bends and circuit ends with PB02911 pipe clips. Connect circuit tails to the manifold using conduit pipe (CPC1525 or CPC2225) to protect the pipe through the screed perimeter. Have the screed contractor pour after system pressure testing — leave the system pressurised during screeding to reveal any accidental damage.

For 12mm pipe installations — such as the Polypipe Overlay system — use the Overlay™ floor panel range (PB08570 \/ PB08571), which has grooves sized for 12mm pipe. Using 12mm pipe in the PB08576 castellations would not secure the pipe correctly or maintain the minimum bend radius.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"pp-faq-item\"\u003e\n    \u003ch3\u003eDo the panels need to be fixed to the insulation?\u003c\/h3\u003e\n    \u003cp\u003eThe panels sit on the insulation boards and are held in position by the weight of the screed and the interlocking panel joints. In most installations, no additional fixing of the panels to the insulation is required — the pipe tensioning and serpentine routing holds the panels flat.

The required insulation thickness depends on the floor type (ground floor, intermediate floor, over unheated space), the building's U-value target, and local Building Regulations requirements. A minimum of 50mm EPS is typical for ground floors; consult your UFH designer or Building Control for the specific requirement for your project.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"pp-faq-item\"\u003e\n    \u003ch3\u003eCan I use the panels with both spiral and serpentine layouts?\u003c\/h3\u003e\n    \u003cp\u003eYes — the red panel system supports both spiral (snail) and serpentine (boustrophedon) pipe layouts. Polypipe recommends the spiral configuration where possible, as it produces more even temperature distribution across the floor — each circuit has both the flow and return legs interleaved, preventing distinct hot and cool zones.

This makes it easy to run in straight lines but difficult to route through tight bends and complex patterns. Underfloor heating requires the opposite: pipe needs to be laid in continuous serpentine or spiral patterns with small-radius bends repeated dozens of times across the floor area.\u003c\/p\u003e\n  \u003cp\u003ePolypipe's UFH Ultra Flex pipe is specifically formulated for this application. It is significantly more flexible than standard plumbing grade barrier pipe, allowing easy routing through the castellations of the Red Floor Panel (PB08576), over the clip rail (CLIPRL), or across the floor with a staple gun, with minimal effort and without the pipe trying to spring back. When unrolling, take the pipe from the \u003cstrong\u003eoutside of the coil\u003c\/strong\u003e and unroll in the direction of travel — this prevents twisting and kinking. The Red Floor Panel guides ensure the minimum bend radius is automatically maintained, eliminating the risk of pipe deformation at bends.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n  \u003cdiv class=\"pp-grid\"\u003e\n    \u003cdiv class=\"pp-card\"\u003e\n\u003cstrong\u003e🔄 Ultra Flexible Polybutylene\u003c\/strong\u003eSignificantly more flexible than standard plumbing barrier pipe.

Applied as a 3mm bead along the top edge of each panel before laying, the expanding polyurethane foam cures to form a rigid, permanent bond between adjacent panel edges and between panels and the Overlay end returns (PB08573) — creating a monolithic, movement-free panel assembly that holds the 12mm pipe grooves in alignment across the full floor area.

As the 12mm pipe is routed through the panel grooves and end returns, the entire floor assembly acts as a rigid substrate that must not shift, separate, or allow panel edges to lift during and after installation. Standard construction adhesives — PVA, grab adhesives, tile adhesive — do not provide the combination of properties required: fast tack, expanding fill to bridge minor panel edge gaps, compatibility with the expanded polystyrene or gypsum board panel materials, and sufficient bond strength to resist the tension of laid pipework.\u003c\/p\u003e\n  \u003cp\u003eThe PB776 polyurethane expanding foam adhesive provides all of these properties in a single product. The foaming action fills any minor surface irregularities between panel edges, maximising contact area and bond strength. The cured foam is rigid, lightweight, and compatible with all Overlay panel materials. Using PB776 — rather than a substitute adhesive — ensures the panel installation meets Polypipe's system requirements and prevents panel separation over the lifetime of the installation.\u003c\/p\u003e\n\n  \u003ch2\u003eStep-by-Step Application\u003c\/h2\u003e\n  \u003col class=\"pp-steps\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrepare panel edges.\u003c\/strong\u003e Clean the top edges of the panel to be glued — remove any dust, dirt, or debris.

The 22mm internal bore provides the clearance needed to sleeve a single 15mm UFH pipe run, allowing the pipe to move freely within the conduit at thermal expansion joints rather than bearing directly against the screed edge — which would cause localised stress and potential pipe damage over time.

Where a screed contains a structural expansion joint — a deliberate break in the screed to accommodate movement — any UFH pipe crossing the joint must be sleeved in conduit. The conduit allows the screed panels on either side of the joint to move independently without applying shear force to the bare UFH pipe.

In the clip rail system, rows of 1m clip rails (CLIPRL) are fixed across the insulation boards at 1m intervals using the PB02911 pipe clips, pushed through the clip rail openings and into the insulation. The UFH pipe is then clipped into the notches of the clip rail at the required spacing, traversing the floor in a serpentine pattern. At circuit ends, the pipe is bent through 180° within the clip notches, and PB02911 clips are additionally used to secure the pipe at bends and entry\/exit points.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFixes clip rail and pipe simultaneously\u003c\/strong\u003e — the clip is pushed through the clip rail body and into the insulation below, anchoring the rail flat and securing the pipe within the rail notch in a single operation\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatible with 15mm and 18mm pipe\u003c\/strong\u003e — the clip accommodates both standard UFH pipe sizes used in solid floor systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWRAS approved\u003c\/strong\u003e — the clip material is approved for contact with heating system water and components; no risk of contamination or material degradation in heating system environments\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBS EN ISO 9002 manufacture\u003c\/strong\u003e — produced under a BSI registered quality management system, ensuring consistent dimensional accuracy and clip strength across the pack\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHand-pressed — no special tools required\u003c\/strong\u003e — clips are pressed by hand into the insulation board through the clip rail, requiring no staple gun, nail gun, or power tools; suitable for all installer experience levels\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e250-clip packs — trade quantity\u003c\/strong\u003e — sized for efficient ordering on trade installations; one pack covers approximately 50m² at standard pipe density, making quantity calculation straightforward\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eInstallation Guide\u003c\/h2\u003e\n  \u003cp\u003eLay clip rails (CLIPRL) across the insulation at 1m intervals, perpendicular to the intended pipe run direction. Push PB02911 clips through the clip rail at 200mm centres to anchor each rail flat against the insulation. Continue fitting clip rails across the full floor area, leaving sufficient clearance at the room perimeter for pipe returns and circuit entry\/exit tails. Lay UFH pipe from the outside of the coil into the clip rail notches at the required spacing — 200mm centres for 15mm pipe, 200mm or 300mm centres for 18mm pipe. At the end of each serpentine row, bend the pipe through 180° and use additional PB02911 clips to secure the bend radius parallel to the adjacent circuit. Run pipe tails from the circuits back to the manifold position through conduit pipe (CPC1525) to protect the pipe through the floor perimeter.\u003c\/p\u003e\n\n  \u003cdiv class=\"pp-callout\"\u003e\n    \u003ch3\u003e📐 Quantity Calculation\u003c\/h3\u003e\n    \u003cp\u003eUse approximately \u003cstrong\u003e1m of clip rail per m² of floor area\u003c\/strong\u003e (i.e. one 1m CLIPRL per m²).

Whereas the Red Floor Panel uses a pre-formed castellated grid to position the pipe, the clip rail system uses slim plastic strips (the clip rails) fixed to the insulation at regular intervals, with the pipe clipped into the notches in the rail surface. This approach is generally considered the more traditional of the two methods, and offers some practical advantages: the clip rail system uses less material on site than floor panels, stores more compactly, and is slightly faster to install in regular rectangular rooms where the serpentine routing is straightforward.\u003c\/p\u003e\n  \u003cp\u003eClip rails are laid perpendicular to the intended pipe run direction, at 1m spacing across the insulation. The UFH pipe is then laid in a continuous serpentine pattern, clipped into the rail notches at 200mm spacing for 15–16mm pipe (200mm or 300mm for 18mm pipe), and bent through 180° at circuit ends using PB02911 clips to secure the bends.

Use PB02911 pipe clips to anchor each rail strip at 200mm intervals along its length, pressing the clips through the rail into the insulation. Continue laying rails until the full floor area is covered.

Route the pipe through the conduit sleeve (CPC1525) at the manifold tail position and across the floor in a serpentine pattern, clicking the pipe into the rail notches at 200mm centres. At each circuit end, bend the pipe through 180° — keeping the bend edge parallel to the adjacent circuit — and secure with PB02911 clips through the insulation. Return the pipe along the adjacent rail row in the opposite direction. Continue until the circuit is complete. Connect circuit tails back to the manifold. Pressure test before screeding.

Polypipe's 15mm UFH barrier pipe (UFH5015B etc.) can also be used in the clip rail system — the pipe will clip into the rail notches, which are sized to hold 15–18mm pipe securely. For 15mm pipe, use 200mm pipe centres. The important distinction is that if you are using 15mm pipe with the clip rail system, you are following the standard clip rail installation method — the Red Floor Panel (PB08576) is an alternative that provides 100mm spacing capability for higher-output applications.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"pp-faq-item\"\u003e\n    \u003ch3\u003eHow do I fix the clip rail to the insulation if it doesn't have its own adhesive?\u003c\/h3\u003e\n    \u003cp\u003eThe CLIPRL clip rail is fixed to the insulation using \u003cstrong\u003ePB02911 standard UFCH pipe clips\u003c\/strong\u003e — the same clips used to subsequently secure the UFH pipe within the rail. Push one clip through the clip rail body into the insulation at 200mm intervals along each rail length. The clip anchors the rail flat against the insulation and also creates the fixing point for the pipe when laid.

However, in practice, clip rail can be used in irregular or awkward areas of a floor (around columns, in narrow alcoves) where cutting floor panels would be wasteful, while panels are used in the main open floor area. This is an installer preference decision and does not affect system performance provided pipe spacing and circuit lengths remain within the specified limits.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pp-infobox\"\u003e\n    \u003cstrong\u003eℹ️ Related clip rail system products:\u003c\/strong\u003e \u003cstrong\u003ePB02911\u003c\/strong\u003e Standard UFCH Pipe Clip Pack of 250 (fixes rail to insulation and pipe to rail) · \u003cstrong\u003eUFH5015B–UFH15015B\u003c\/strong\u003e 15mm UFH Barrier Pipe Coils · \u003cstrong\u003eCPC1525\u003c\/strong\u003e 15mm Conduit Pipe Coil (manifold tails and bend former) · \u003cstrong\u003eCPC2225\u003c\/strong\u003e 22mm Conduit Pipe Coil (expansion joints) · \u003cstrong\u003ePB08576\u003c\/strong\u003e Red Floor Panel (alternative pipe positioning system for 100mm spacing or spiral layouts)\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Polypipe","offers":[{"title":"Default Title","offer_id":63633884152157,"sku":"CLIPRL","price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/1mtrLengthClipRailtofit16mm-18mmForUnderfloorHeating.jpg?v=1772129979"},{"product_id":"polypipe-zonal-regulation-unit-2-3-circuit-zru-complete-with-manifold","title":"Polypipe Zonal Regulation Unit 2\/3 Circuit ZRU Complete with Manifold","description":"\u003cstyle\u003e\n\/* ── Reset \u0026 Base ────────────────────────────────────────────────────── *\/\n.qh-pd, .qh-pd *::before, .qh-pd *::after { box-sizing: border-box;

It bridges the temperature gap between a radiator system (typically 70–80°C flow) and the lower temperatures required for underfloor heating (30–55°C) using a built-in thermostatic blending valve. A dedicated pump within the unit provides the correct flow rate for the UFH loops independently of the existing system pump. The PB970028 variant includes a built-in 2-circuit manifold as standard; a third circuit can be formed by adding two 15mm spigot elbows and two 15mm tees (sold separately).\n  \u003c\/p\u003e\n\n  \u003c!-- ── Key features ── --\u003e\n  \u003cdiv class=\"section-label\"\u003eKey Features\u003c\/div\u003e\n  \u003cul class=\"feat-list\"\u003e\n    \u003cli\u003eConnects single rooms or extensions up to 30 m² to any existing 2-pipe wet heating system\u003c\/li\u003e\n    \u003cli\u003eNo hydraulic or electrical alterations to the existing heating system required\u003c\/li\u003e\n    \u003cli\u003eBuilt-in thermostatic blending valve blends flow water to the correct UFH temperature (30–60°C)\u003c\/li\u003e\n    \u003cli\u003eDedicated integral pump boosts flow — UFH loops are not dependent on the existing system pump\u003c\/li\u003e\n    \u003cli\u003eBuilt-in pipe thermostat senses available heat — pump only runs when boiler water exceeds 45°C\u003c\/li\u003e\n    \u003cli\u003eOptional volt-free room thermostat or wireless sensor connection for precise air temperature control\u003c\/li\u003e\n    \u003cli\u003e2-circuit manifold built in as standard — expandable to 3 circuits with standard 15mm fittings\u003c\/li\u003e\n    \u003cli\u003eCan operate the UFH zone independently of the rest of the heating system when used with a zone valve\u003c\/li\u003e\n    \u003cli\u003eAlso suitable for low surface temperature (LST) radiator applications where water temperature control is needed\u003c\/li\u003e\n    \u003cli\u003eWall-mounted in the heated room or positioned elsewhere in the property — fully flexible siting\u003c\/li\u003e\n    \u003cli\u003eSuitable for domestic and commercial buildings\u003c\/li\u003e\n    \u003cli\u003eCompatible with all Polypipe UFH systems: Overlay™, Overlay™ Lite, MHP, solid screeded floors, and more\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003c!-- ── What's in the box ── --\u003e\n  \u003cdiv class=\"section-label\"\u003eWhat's Included\u003c\/div\u003e\n  \u003cdiv class=\"box-grid\"\u003e\n    \u003cdiv class=\"box-item\"\u003eZonal Regulation Unit body (pump, blending valve, pipe stat)\u003c\/div\u003e\n    \u003cdiv class=\"box-item\"\u003e2-circuit built-in manifold (flow \u0026amp; return)\u003c\/div\u003e\n    \u003cdiv class=\"box-item\"\u003eWiring module with terminal block\u003c\/div\u003e\n    \u003cdiv class=\"box-item\"\u003eWall fixing template \u0026amp; screws\u003c\/div\u003e\n    \u003cdiv class=\"box-item\"\u003eFixing plugs\u003c\/div\u003e\n    \u003cdiv class=\"box-item\"\u003eInstallation guide\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"callout callout-teal\"\u003e\n    ℹ️ \u003cstrong\u003e3rd circuit upgrade:\u003c\/strong\u003e To form a third heating circuit, add 2 × 15mm spigot elbows and 2 × 15mm tees to the ZRU manifold ports.

The built-in thermostatic blending valve reduces the flow temperature to between 30°C and 60°C before it reaches the UFH pipework.

The pipe thermostat within the unit detects when flow water reaches 45°C and only then starts the UFH pump. If the boiler is off, the ZRU pump will not run.
