I. The Complete System Un’unica fonte italiana
One PPR System: Pipes, Fittings & Valves From a Single Italian Source
Distributors lose sales over one missing fitting. WARMHAUS supplies the entire PPR cold and hot water line as one same-material system, so your customers never have to source a coupling elsewhere.
Interim photo · CC BY-SAFittings Range La gamma di raccordi
Every joint in the line, one catalogue
Elbows, tees, reducers, male and female threaded adapters, unions, crossover bends, flanges and pipe clips — the complete companion range to our PPR pipes, engineered to the same sizing so pipe and fitting always match on site.
Because pipes and fittings share the same PP-R material, every joint is hot-melt welded into a single homogeneous body — no glue, no threads, no leak points at the fitting.

PPR Pipes — Cold & Hot Water
Cold and hot water supply pipes produced across the PN series, matched to the pipe class your drawings specify — with the standard reference and Made-in-Italy origin printed on the pipe body.
View PPR PipesPPR Fittings — Elbows to Flanges
Elbows, tees, reducers, male/female threaded adapters, unions, crossover bends, flanges and clips — the full connection range in the same PP-R material as the pipe.
View PPR FittingsPPR Valves — Weld-in Shutoff
PPR ball valves and stop valves — same-material shutoff that welds directly into the line, keeping the whole run one homogeneous system from riser to tap point.

PN Pressure & Temperature Ratings for Cold and Hot Water
Project procurement buys to the drawing. WARMHAUS PPR is produced in a PN series engineered for both cold and hot water supply, so each run matches the pipe class your MEP specification calls out.

IV. Certifications Certificazioni tedesche
Material Grade & German-Certified Quality
The moat of Made in Italy is not the flag — it is verifiable quality. WARMHAUS PPR is produced from random-copolymer polypropylene (PP-R) selected for consistent long-term pressure performance, and carries the marks that open engineering tenders and retail shelves across the Gulf, North Africa and Europe.
PP-R raw-material grade / source and drinking-water hygiene approvals: Coming soon. Certificate numbers and issuing bodies are confirmed on request.
V. On Site Saldatura a caldo
A Hot-Melt Weldable System — No Glue, No Leaks at the Joint
For installers, every leak at a joint is money out of their own pocket on rework. A same-material system removes the weak point entirely.
Interim photo · CC BY-SAOne Material Un corpo unico
Joints as strong as the pipe itself
Because WARMHAUS pipes, fittings and valves are all the same PP-R material, they fuse by hot-melt welding into one continuous body — no solvent glue, no threaded seals, no O-rings to fail at the connection.
One system means one welding process on site, consistent sizing across pipe and fitting, and a joint that is as strong as the pipe itself. We also supply the matching PPR welding machines, so your installers work with tooling proven on our own system.
