Project & Spec Piping Supply — One Certified System for MEP & Developers
Spec Hitze into your project and source the whole water path from one accountable German brand: PEX, PEX-AL-PEX multilayer and PE-RT pipe with matched fittings and underfloor-heating manifolds.
Submittal-grade DoP and TDS data, BIM support, a system-level warranty and delivery phased to your construction program. Certified to cUPC, NSF-61, DVGW, WRAS and CE (with DoP), for projects across North America and Europe.
Trade & project supply only — MEP consultants, developers, contractors and distributors. Not a retail storefront.
cUPC · NSF-61 · DVGW · WRAS · CE + DoPThe System, On the Project
One Brand From the Extrusion Line to the Riser
Pipe, fittings and manifolds engineered, certified and shipped as one system — from our production floor to your submittal package and your construction program.
Single-Source System
Spec One System, Not Three Vendors — Pipe, Fittings & Manifolds Under One Brand
Split the piping package across suppliers and you own the interface risk. Specify one certified system and one source is accountable for the whole water path.
Hitze supplies the complete potable and hydronic water path as a single, matched system: multilayer PEX-AL-PEX and PE-RT pipe with an EVOH oxygen barrier per DIN 4726, PEX for heating and potable, press / push-fit / compression / brass fittings matched to the pipe, and underfloor-heating manifolds. Because every component shares the same brand, the same jaw profiles (TH / U / F / M) and the same certification family, compatibility is designed in — not something your installer discovers on site. Lead-free / DZR brass (CW724R / CW511L / CW602N) meets potable requirements — see our lead-free brass press fittings — and the whole system is certified to cUPC, NSF-61, DVGW, WRAS and CE with DoP.
| System component | Line | Standards | Role in the water path |
|---|---|---|---|
| Multilayer PEX-AL-PEX pipe | Multilayer PEX-AL-PEX | EN ISO 21003, ASTM F1281/F1282 | Heating + potable risers/mains |
| PEX pipe | PEX Pipe | EN ISO 15875, ASTM F876/F877 | Heating + potable distribution |
| PE-RT underfloor heating pipe | PE-RT UFH Pipe | DIN 4726 (O₂ barrier) | Hydronic radiant loops |
| Press / push-fit / compression / brass fittings | Press Fittings | NSF/ANSI 61, lead-free / DZR brass | Joints, transitions, isolation |
| Underfloor heating manifolds | UFH Manifolds | Matched to system pipe | Loop distribution + balancing |
Submittal-Grade Data
BIM Objects, DoP & TDS You Can Drop Into the Spec
A brochure doesn’t clear a submittal. MEP consultants get modeling and compliance data built to go straight into the design and the approval package.
For the design stage, Hitze provides BIM objects so pipe, fittings and manifolds load into your Revit or IFC model without rebuilding families by hand. For the submittal, every product carries a Declaration of Performance (DoP) — backed by held CE certification — and a Technical Data Sheet (TDS) with pressure/temperature ratings, dimensions, tolerances and standards, so you cite real numbers in the spec instead of chasing a rep for a datasheet before deadline. Certification references (cUPC / IAPMO, NSF-61, DVGW, WRAS, CE + DoP) accompany the package; certificate and listing numbers are provided in the Hitze Cert Pack and are verifiable at source.
| Submittal asset | Format / basis | Status |
|---|---|---|
| BIM objects (pipe / fittings / manifolds) | Revit .rfa / IFC — format & coverage detailed in the technical data sheet | Available on request |
| Declaration of Performance (DoP) | CE + DoP (held) | Available — DoP number on request |
| Technical Data Sheet (TDS) | Pressure/temp, dimensions, tolerance, standards | Available per line |
| Certification references | cUPC / NSF-61 / DVGW / WRAS / CE | Held — numbers in the Hitze Cert Pack, verifiable at source |

System Warranty
One System, One Warranty — Coverage on the Assembly, Not Just the Pipe
A pipe warranty is worthless if the leak is at a fitting from another brand. Specify a matched system and the warranty covers how the parts perform together.
When pipe, fittings and manifolds come from one brand, tested and certified as a set, the warranty can cover the assembled system rather than a single component — which is what a developer actually needs on a build that has to perform for decades. Mixing brands at the joint is where responsibility fractures and where a claim gets denied. A same-brand Hitze system removes that gap: one accountable source stands behind the whole water path, backed by a 50-year warranty on the matched Hitze pipe-and-fitting system. Coverage terms are confirmed per project.
| Warranty point | Detail |
|---|---|
| Scope | Assembled same-brand system (pipe + fittings + manifolds) |
| Condition | Matched Hitze components, installed to spec |
| Warranty term | 50-year warranty on the matched Hitze pipe-and-fitting system |
| Coverage terms | Coverage, claim process and exclusions confirmed per project |
The matched Hitze pipe-and-fitting system carries a 50-year warranty; full coverage terms are confirmed per project — see the system-warranty page for the current program.
Phased Delivery
Material Lands When the Trade Needs It, Not Before
Everything on site at once clutters the build and ties up cash; late material stalls a trade. We plan releases against your construction program.
Rough-In
Distribution pipe released first so the plumbing trade can run the water path before walls close.
Manifolds
Underfloor-heating manifolds and matched fittings land as the loops go in — not sitting exposed on site early.
Fit-Out
Finish fittings and isolation components arrive at fit-out, so each trade gets its material on schedule.
Instead of one dump delivery, project supply can be released in phases tied to your program — rough-in pipe first, manifolds when the loops go in, fittings and finish components at fit-out — so material arrives when each trade needs it and doesn’t sit exposed on site. For importers and contractors buying by the container, mixed-SKU loads are planned for fill rate so you’re shipping product, not air — install crews can also work through our radiant heating supply for contractors & installers. Phasing schedule, lead time and shipping documentation are set at consultation.
| Logistics point | Detail |
|---|---|
| Delivery model | Phased releases tied to construction program |
| Typical phases | Rough-in → manifolds → fit-out (tailored per project) |
| Lead time | Confirmed at consultation against your construction program |
| Container loading | Mixed-SKU planned for fill rate (40HQ) |
| Shipping docs | Compliance set + Certificate of Origin + invoice / packing list / BoL |
Trade-only note: This page and its project pricing are for the trade — MEP consultants, developers, contractors, distributors and importers. Not a retail storefront; no consumer single-unit sales.
Warehouse & Supply
Stock on Pallets, Ready to Release to Your Program
Coiled pipe and branded fittings cartons staged on pallets in the warehouse — the same stock that ships in phases against your construction schedule.
How We Supply a Project
From Spec to Phased Delivery — How Hitze Backs a Build
Here is how a project engagement runs — from the first sample to phased delivery on the matched pipe, fitting and manifold system.
A project buyer typically starts with samples or a small trial order — Hitze has no MOQ, so you can validate the pipe, fittings and manifolds before committing to volume. From there the certified system is specified into the design with submittal-grade DoP and TDS data, then released in phases tied to the construction program. Whether you are a developer, MEP consultant or general contractor in North America or Europe, one accountable source stands behind the whole water path, backed by the 50-year system warranty.
| Engagement detail | How Hitze supports it |
|---|---|
| Buyer type | Developers, MEP consultants, general contractors, distributors and importers |
| Region | Projects across North America and Europe |
| Project type | Multi-unit residential, commercial hydronic and whole-house piping builds |
| System supplied | Matched pipe lines + fittings + underfloor-heating manifolds, one brand |
| First-order scope | No MOQ — start with samples or a small trial order, scale to container supply |
| Timeline | Spec-in with DoP/TDS → phased delivery to the construction program → 50-year system warranty |
A single-source system, submittal-grade DoP/TDS data and delivery phased to your program are built to take project risk out of the water path — one accountable brand from the extrusion line to the riser.How Hitze supports project & spec buyers
