WebbIn the 80’s and 90’s similar small bore, 10mm pipes were all the rage in underfloor heating. The concept of small bore pipes for UFH is not new. Admittedly, in the 90’s these were set into the screed, but the principle is the same, in that small areas, typically 10~12m2 were each heated by a small pipe, requiring 2~3 circuits for an typical room. WebbManifolds are essentially the control hubs for central heating systems, specifically underfloor heating (UFH).
