For areas exceeding 100m of pipe, split into multiple circuits on the manifold.\u003c\/p\u003e\n\n  \u003ch2\u003eWhy Ultra Flexible?\u003c\/h2\u003e\n  \u003cp\u003eStandard polybutylene barrier pipe — as used in conventional plumbing — is designed to be self-supporting and relatively rigid. 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.

Choose the next coil size up. For example: a 15m² floor at 200mm centres needs 15 × 4.5 = 67.5m of pipe, plus 8m of tails = 75.5m total — specify the 80m coil. Avoid over-specifying; excess pipe that has been unrolled cannot be re-used in the system as a partial circuit of reduced length would create flow imbalance.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"pp-faq-item\"\u003e\n    \u003ch3\u003eCan I join two coils together in one circuit?\u003c\/h3\u003e\n    \u003cp\u003eNo. UFH circuits must be continuous runs of pipe with no joints within the floor structure. Joints in buried pipe create an unacceptable risk of leaks after screeding, which would require breaking out the screed to repair. Each circuit should be a single unjoined coil from manifold to manifold.

The Overlay floor panels and end returns are grooved for 12mm pipe only. The 15mm pipe is for solid screeded floor applications (panel system and clip rail system) where 15mm and 18mm pipe sizes are used. Using 15mm pipe in Overlay panels would prevent correct installation and panel joints from seating.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pp-infobox\"\u003e\n    \u003cstrong\u003eℹ️ Related products:\u003c\/strong\u003e PB08576 Red Floor Panel (pipe positioning for solid floors) · CLIPRL 1m Clip Rail (alternative pipe fixing method) · PB02911 Pipe Clip Pack of 250 (clip rail system fixings) · CPC1525 \/ CPC2225 Conduit Pipe Coil (protects pipe tails through screed edge and manifold connections)\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Polypipe","offers":[{"title":"50m","offer_id":63633548673373,"sku":"UFH5015B","price":99.0,"currency_code":"GBP","in_stock":true},{"title":"80m","offer_id":63633548706141,"sku":"UFH8015B","price":150.0,"currency_code":"GBP","in_stock":true},{"title":"100m","offer_id":63633548738909,"sku":"UFH10015B","price":190.0,"currency_code":"GBP","in_stock":true},{"title":"120m","offer_id":63633548771677,"sku":"UFH12015B","price":230.0,"currency_code":"GBP","in_stock":true},{"title":"150m","offer_id":63633548804445,"sku":"UFH15015B","price":290.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/PolypipeUFHUltraFlexibleBarrierPipeCoil15mmUnderfloorHeatingPipe50m_150m.jpg?v=1772127505","url":"https:\/\/qualityheating.co.uk\/products\/polypipe-ufh-ultra-flexible-barrier-pipe-coil-15mm-underfloor-heating-pipe-50m-150m","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
