Underfloor Heating
Brass Underfloor Heating Manifold — 2 to 8 Ports, Low-Lead
A manufacturer of complete underfloor heating systems, producing since 1993. Brass manifolds in 2 to 8 ports, with a flow-meter version for easy balancing — engineered to work as one system with our PEX-B pipe, electrothermal actuators and thermostats. ISO 9001, ISO 14001, CE & SGS certified.
We supply importers, wholesalers and projects — trade and project quantities only. We do not sell single manifolds to consumers.
I. The Range Da 2 a 8 vie
Brass Manifolds From 2 to 8 Ports — One Port Per Heating Loop
Every underfloor heating loop needs one supply and one return outlet — so the number of ports you order is simply the number of floor circuits the manifold will feed.
One Body, Six Sizes
Scale the Outlets, Keep the Proven Body
Our brass manifolds are built as a full range from 2 to 8 ports, so a compact apartment and a full villa floor run on the same machined body — you scale the outlet count, not the quality. End caps, mounting brackets, air vents and drain valves come as a matched set, and every size is dimensioned for our PEX-B pipe, actuators and thermostats out of the box.
For wholesalers, one body across six sizes keeps the SKU count and reordering simple; for installers, every size mounts, connects and balances the same way.
See the full underfloor heating system| Ports | Heating Loops Served | Typical Layout | Flow-Meter Option | Dimensions & Centre Distance |
|---|---|---|---|---|
| 2 ports | Up to 2 loops | Single-room extension, small bathroom zone | Available | on the datasheet |
| 3 ports | Up to 3 loops | Studio or one-bedroom apartment | Available | on the datasheet |
| 4 ports | Up to 4 loops | Small apartment | Available | on the datasheet |
| 5 ports | Up to 5 loops | Larger apartment | Available | on the datasheet |
| 6 ports | Up to 6 loops | Family house floor | Available | on the datasheet |
| 8 ports | Up to 8 loops | Villa floor, large open-plan level | Available | on the datasheet |
Typical layouts are general sizing guidance — count the actual loops on your plan and round up to the next port size. Dimensions, flow range and brass grade: confirmed on the datasheet.
Count Your Loops
One PEX circuit per room or zone. Total loops = ports needed — each loop takes one supply and one return outlet.
Pick the Port Count
Round up to the next size — 2, 3, 4, 5, 6 or 8 ports — for spare capacity on future zones.
Plain or Flow-Meter
Choose the flow-meter version whenever loops differ in length, so the system balances by eye.
Confirm on the Datasheet
Dimensions, flow range and brass grade are confirmed on the datasheet before you order.
II. Flow-Meter Version
The Flow-Meter Version — Balance Every Loop by Eye
A visual flow gauge on every supply outlet turns hydronic balancing from a calculation into a glance.
When a short bathroom loop and a long living-room loop share one manifold, the short loop steals the flow and the big room stays cold. The flow-meter version puts a gauge on every supply outlet, so the installer sets the litres-per-minute of each loop and reads it directly — no calculation, no guesswork, even floor temperatures. Fewer cold spots means fewer callbacks for your installers, and fewer warranty complaints back up the chain.
III. Material & Build Certified brass
Machined From Brass, Third-Party Certified, Producing Since 1993
The manifold is the hydronic heart of an underfloor system — it runs hot water for decades, so the body material is not a detail to cut corners on.
Our manifolds are machined from brass for corrosion resistance and dimensional stability under thermal cycling, on our own machining lines, by a manufacturer building piping systems since 1993. Every batch is made under ISO 9001 quality and ISO 14001 environmental management, and the wider system carries ISO 45001, EU CE and Swiss SGS certification — production runs to DIN 8077 / DIN 8078 and GB/T 18742.2-2017, and every item is checked against its specification before it leaves the plant. Those are the credentials project buyers and Gulf-market importers look for on a submittal, because a reviewer can check them without taking our word for anything. Certificate numbers: available on request.
| Item | Value | Detail |
|---|---|---|
| Body material | Brass | Exact alloy grade: confirmed on the datasheet |
| Pressure / temperature rating | available on request | PN and working temperature confirmed on the datasheet |
| Production | Own machining lines — manufacturer, not trader | Manufacturing piping systems since 1993 |
| Certifications | ISO 9001:2015 · ISO 14001:2015 · ISO 45001:2018 | EU CE · Swiss SGS · Russian PT — certificate numbers available on request |
IV. One System
Compatible With PEX Pipe, Actuators and Thermostats — From One Supplier
A manifold on its own is half a system. Ours is engineered as part of a complete WARMHAUS underfloor heating set, so the pieces fit without adapters or surprises.
PEX-B Pipe (1216 / 1622)
Outlet connections sized for our PEX-B underfloor heating pipe — correct diameter from the same catalogue, no mixed-brand adapters between pipe and manifold.
Electrothermal Actuators
Designed for standard M30×1.5 valve thread — thread specification confirmed on the datasheet. Actuators seat directly on the manifold return bar for per-loop shut-off.
Room Thermostats
Wired to the actuators for per-room control — matched signal and voltage across the set, so zoning works the first time it is powered on.
Fittings & Accessories
Brass inserts, end sets, mounting brackets, air vents and drain valves from the same catalogue — one order, one delivery, one warranty for the whole loop.
Buying manifold, pipe, actuator and thermostat from one manufacturer removes the biggest failure point in imported heating projects — mismatched diameters, threads and control signals — and gives your customers one warranty for the whole system. With PPR, HDPE, PEX, PE-RT, brass fittings and valves and underfloor heating in a single catalogue — backed by three plants totalling 100,000 m² of building area and 2,000 tonnes a month of total output — the whole set can also travel in one mixed container.
V. Installation
Installing and Balancing the Manifold — The Short Version
The outline in four moves — the full step-by-step, with a balancing walk-through, lives in our installation guide.
The manifold mounts in a wall recess or cabinet above the floor loops, with the supply bar fed from the boiler or heat pump and the return bar carrying water back. On the flow-meter version, you balance by setting each loop’s gauge to its target litres-per-minute — longer loops open wider, shorter loops throttle down — until the floor heats evenly.
FAQ Common questions
Underfloor Heating Manifold — Frequently Asked Questions
One port per heating loop — count the PEX circuits leaving the manifold. Each room or zone is usually one loop, so a 4-port manifold suits a small apartment and an 8-port a larger floor. Round up to the next size for spare capacity; our brass manifolds run 2 to 8 ports.
Stock the mid-range — 4, 5 and 6-port bodies cover most residential jobs your installers ask for, with 2-port for small extensions and 8-port for villas. One brass body across the range keeps your SKU count and reordering simple.
A visual flow gauge on every outlet, so you set and read each loop’s litres-per-minute and balance the floor by eye — no calculation. It pays for itself on any job mixing long and short loops, and it makes balancing verifiable on commissioning — you can show each loop’s set flow at handover. Available across the 2-to-8-port range. Flow range: confirmed on the datasheet.
It is designed as one system with our PEX-B pipe (1216 / 1622), standard M30×1.5 electrothermal actuators and room thermostats — diameters, threads and signals match with no adapters. Mixing brands is where leaks and mis-fits start, so we recommend the matched set from one supplier. Actuator thread specification: confirmed on the datasheet.
The body is machined from brass for corrosion resistance and long hydronic life, on our own lines, by a manufacturer producing since 1993. It is covered by ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, EU CE, Swiss SGS and Russian PT — third-party credentials that clear project submittals and Gulf-market approvals. Certificate numbers are available on request. If your market requires an additional approval, ask us and we will confirm in writing exactly what we hold. Exact brass grade and PN rating: on the datasheet.
The like-for-like comparison is build (solid brass body), a full 2-to-8-port range, an integrated flow-meter version, and documented compliance — ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, EU CE, Swiss SGS and Russian PT — plus the matching PEX pipe, actuators and thermostats from the same manufacturer under one warranty, instead of assembling a system from several brands. Spec us on the certificates and the datasheet rather than on a brand story: the certificates are checkable, and that is what a tender reviewer actually reads. Ask for the datasheet to compare against your current line.
Yes. As a manufacturer we ship brass underfloor heating manifolds to importers, wholesalers and projects across the Gulf, North Africa, Southern and Eastern Europe and Latin America — and there is no minimum order quantity, so a first trial order can be sized to your market. Standard production lead time is 45 days from order confirmation, which is worth building into your stock planning. ISO 9001, ISO 14001, ISO 45001, EU CE, Swiss SGS and Russian PT certificates are what customs and tender committees ask for, and we supply the documents with the shipment. See Countries We Supply.
