Hitze Insights
Specification, certification and sourcing guides for wholesalers, contractors and private-label brands — written from the Hitze engineering desk.

Begin with the system overview, then use the latest technical articles for a specific decision.
What is PPR pipe? Understand PP-R materials, fusion, standards, sizes, ratings, potable-water checks, installation and project selection.
PEX-a vs PEX-b vs PEX-c by manufacturing method: crosslinking %, flexibility, kink repair and the one fitting rule that actually matters for your install.
PEX vs PEX-AL-PEX multilayer pipe, decided by the run: oxygen barrier, thermal expansion, jointing and best-for/not-for from a German-brand pipe maker.
Size an underfloor heating manifold by loop count and flow rate: ports, flow meters, brass vs stainless, and the interfaces that actually fit.
Press, compression or push-fit? A contractor's guide to which joint won't leak: code limits (ASSE 1061, IAPMO), jaw profiles and pipe-tolerance traps.
