Can Hitze supply a complete radiant floor heating system, not just pipe?

Yes. Hitze supplies the full hydronic radiant system under one brand: oxygen-barrier (DIN 4726 / EVOH) PE-RT pipe, brass or stainless 2–12 port manifolds with flow meters, and matched connectors. Single-source means one supplier owns compatibility across the loop.

Why does a radiant heating loop need an oxygen barrier?

In a sealed hydronic loop, oxygen diffusing through non-barrier pipe corrodes the boiler, pump and steel manifold parts. An EVOH oxygen-barrier layer to DIN 4726 blocks that diffusion, protecting metal components over the system's life.

Q: Can delivery be phased to match a construction schedule?

Yes. For phased radiant projects Hitze can stage shipments — pipe for the slab pour first, manifolds and controls as each zone goes in — so material lands with the work instead of clogging the yard. Specific lead times are available on request.

One brand for the whole loop — oxygen-barrier PE-RT pipe, matched manifolds, and delivery phased to the build.

Hitze is a German brand of complete heating and potable-water piping systems. This case study shows how a Hitze radiant system comes together for a contractor.

Inside the Project

What a Single-Source Radiant System Looks Like on Site

From plant room to floor loop to commissioning — one matched system, one accountable supplier. (Site photography for authorized projects is being finalized; captioned frames show the shots on the way.)

Boiler, pump, expansion vessel and heating pipework in a hydronic plant room — Plant room — boiler, pump & heating pipe

Manifold install — brass / stainless manifold with per-loop flow meters, wall-mounted

Floor loop layout — PE-RT pipe serpentine on insulation, tied to the grid

Commissioning — loop pressure test with gauge before the slab pour

Phased delivery — pipe coils staged on site for the current pour

The Challenge

A Complete, Oxygen-Tight System — On the Site’s Schedule

The contractor faced three problems that decide whether a radiant floor job runs smoothly or turns into a callback.

A complete system, not parts from three suppliers. Pipe, manifolds and connectors had to be sourced together and guaranteed to fit — so one supplier, not the contractor, owns compatibility across the loop.
A fully oxygen-tight hydronic loop. In a sealed radiant loop, oxygen diffusing through non-barrier pipe corrodes the boiler, pump and steel manifold parts. The system needed a continuous oxygen barrier the mechanical engineer would sign off on.
On-time, phased delivery. Radiant work follows the slab pour and the floor-by-floor build. Everything arriving at once would clog the yard; material had to land with each phase.

Annotated diagram — three pain points: fragmented supply, oxygen ingress to boiler, one-shot delivery clogging the yard

Why the oxygen barrier matters (industry note): An EVOH oxygen-barrier layer to DIN 4726 blocks the oxygen diffusion that would otherwise rust ferrous components over the system’s life. It is not optional on hydronic loops with steel or cast-iron parts.

The Solution

One Compatible Radiant System, Delivered in Phases

Hitze scoped and supplied the entire loop as a single, matched system — then staged it to the build.

A Complete System: Pipe + Manifolds + Connectors

Hitze supplied oxygen-barrier PE-RT pipe (EVOH layer to DIN 4726) for the floor loops, paired with brass / stainless 2–12 port manifolds carrying per-loop flow meters, plus matched Euro-cone / compression connectors. The PE-RT radiant pipe and manifolds are engineered together, so the loop is oxygen-tight end to end — no mixing of barrier and non-barrier components.

Single-Source Compatibility & One Point of Responsibility

Because pipe and manifolds come from one brand, compatibility is designed in — pipe sizes (16 / 20 / 25 mm), fittings and manifold outlets all match, and Hitze — not the contractor — owns the interface. That collapses a multi-supplier bill of materials into one order, one spec pack and one accountable supplier. System warranty terms available on request.

Phased Delivery Aligned to the Build

Delivery was staged to the site: pipe for the slab pour first, manifolds and controls as each zone came online. Material landed with the work instead of sitting in the yard, keeping cash and space tied to progress. Specific batch nodes and lead times are available on request.

Phased to the Build

Material That Lands With the Work

Pipe for the Pour

Oxygen-barrier PE-RT coils ship first, laid on insulation and tied off before the slab pour of each zone.

Manifolds per Zone

Brass / stainless manifolds and controls follow as each zone comes online — matched to the pipe already down.

Commission & Repeat

Loops are pressure-tested and commissioned zone by zone; the next batch lands as the build advances.

Phased delivery timeline — pipe → manifolds → controls mapped to the pour schedule

On client references: Hitze does not publish named client quotes or measured results until a project is authorized for reference. A representative contractor priority for this kind of job is having pipe and manifolds from one brand — taking the compatibility risk off their desk — with phased delivery matched to the pour schedule.

FAQ

Radiant Heating Project FAQ — Contractors, GCs, MEP & Importers

Can I get pipe and manifolds from one supplier for a radiant job?

For the ContractorYes. Hitze supplies the complete hydronic loop under one brand: oxygen-barrier PE-RT pipe (DIN 4726 / EVOH), brass or stainless 2–12 port manifolds with flow meters, and matched 16/20/25 mm connectors. One supplier owns compatibility, so there are no mismatched fittings on site. See contractor supply.

Can delivery be phased to our construction schedule?

For the Developer / GCYes. For phased radiant projects Hitze stages shipments — pipe for the slab pour first, manifolds and controls as each zone goes in — so material lands with the work, not all at once in your yard. Specific lead times are available on request. Start at Plan Your Project.

How is the loop kept oxygen-tight, and to what standard?

For the MEP ConsultantEvery pipe carries an EVOH oxygen-barrier layer to DIN 4726, blocking the oxygen diffusion that corrodes boilers, pumps and steel manifold parts in a sealed hydronic loop. Manifolds are matched so the barrier is continuous. Full specs on the PE-RT pipe page.

Is a system like this repeatable at volume for my market?

For the Importer / DistributorYes. The products used — oxygen-barrier PE-RT pipe and matched manifolds — are standard Hitze lines certified to cUPC, NSF/ANSI 61, DVGW, WRAS and CE. MOQ is low and sample-friendly; certificate numbers and lead times are available on request. Request the Cert Pack to assess it.
