ISITMAXHydronic underfloor heating and pipe system supply: project and wholesale
Pipe, manifolds, insulation panels, valves and fittings for wet underfloor heating and water networks — quoted in coils and cartons against your project's material list. For installers, contractors and distributors.
What we supply
- Underfloor heating pipe — PE-RT (3, 5 or 6 layer, Ø16 mm), PEX-A (DIN EN ISO 15875 / DIN 4726, Ø16–40 mm), PEX-B (Ø16–32 mm, max 95 °C, 10 bar); oxygen barrier or non-barrier, bare or sleeved; 240–600 m coils.
- Manifolds — valved, flow-meter and thermostatic bodies, 2–14 ports; complete manifold sets; manifold cabinets 40/60/80 cm; adaptors, end caps, automatic air vents, brackets.
- Insulation panels — castellated EPS panels, plain or foil-faced, 22–30 kg/m³ density grades.
- Valves — ball valves with butterfly handle ½"–1¼", angle valves, mini manifold valves.
- Fixings — staples for hand and tacker installation, pipe clips 16–32 mm, rails, bend supports.
- Thread sealant — three anaerobic grades, 15–250 ml.
How much material does a project need?
Short answer: pipe per m² follows the pipe spacing — about 10 m at 10 cm spacing, 6.7 m at 15 cm and 5 m at 20 cm. A Ø16 mm circuit is usually kept within 80–100 m, and the manifold needs one port per circuit.
| Pipe spacing | Pipe per m² | Pipe for 100 m² | Area per circuit (100 m pipe) |
|---|---|---|---|
| 10 cm | ≈ 10 m | ≈ 1,000 m | ≈ 10 m² |
| 15 cm | ≈ 6.7 m | ≈ 670 m | ≈ 15 m² |
| 20 cm | ≈ 5 m | ≈ 500 m | ≈ 20 m² |
Add the flow and return runs to the manifold, choose coil lengths (240–600 m) so circuits need no joints, and allow about 5% waste on insulation panels. Exact quantities come from the layout drawing — send the floor plan and we prepare the list.
Water network and HDPE fittings
The same supply covers HDPE water and gas distribution lines: electrofusion couplers, elbows, tees, reducers, end caps, tapping saddles, repair saddles and service tees; injection-moulded and fabricated butt-fusion fittings (elbows 11°–90°, equal and reducing tees, crosses, Y-branches, stub ends); steel, PP-coated steel and blind flanges; PE-to-brass (MS 58) and PE-to-steel transition fittings.
How a quote works
Send the material list — item, diameter, quantity or length — plus the delivery country and the date the site needs it. If there is no list yet, a drawing or the heated area is enough to start. Several product groups go on one quote. Prices are per project: they depend on quantities, packing and freight, so no list prices are published.
Prefer to send the list by e-mail.
Electric alternative for small areas
For single rooms, bathrooms and renovations where the floor cannot be raised, a wet system is rarely worth it. See electric underfloor heating: mats, cable and film, manufactured by ISITMAX.
