Multilayer PEX-AL-PEX pipe, press fittings, manifolds and the complete hydronic pipework system. AHHAC supplies the Italian Aquatechnik Group plumbing and heating range.
The pipework is the circulatory system of a hydronic install — and the quality of the pipe and fittings determines whether the system stays leak-free for 30+ years or becomes a maintenance headache. AHHAC specifies premium multilayer pipe and press-fit fittings on every system.
Our preferred pipework supplier is Aquatechnik Group s.p.a. — Italian-engineered multilayer (PEX-AL-PEX) pipe and the Safety-Pol / Fluxo press-fit fitting systems. Multilayer pipe combines the flexibility of PEX with the oxygen-barrier and shape-retention of an aluminium core, making it ideal for hydronic heating, cooling and potable water.
Multilayer PEX-AL-PEX won't corrode, scale or allow oxygen ingress (which protects steel components like radiators and pumps from rusting). The aluminium layer means the pipe holds its bent shape and expands far less than plain PEX. Press-fit fittings make a permanent, tested joint in seconds with no heat, flame or solvent — faster to install and impossible to under-tighten. AHHAC pressure-tests every circuit before handover.
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."
"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
