Radiant heating design and installation — manifolds, PEX circuits, controls, screed and commissioning.

Low installed cost with high running cost, against the reverse. A side-by-side on total floor build-up including insulation, heat output, controls and the retrofit limits that decide it before cost does.

One process step separates them: PE-RT is not cross-linked, PEX is. Side by side on jointing, the ISO 10508 class table, coil handling and where the two standards genuinely diverge.

One search term, two products that are not interchangeable. Compared on ports, valves, accessories and sizing — plus the G, R, NPT and eurocone thread designations you need to quote.

Bare PEX lets oxygen diffuse into the water, and in a sealed loop that corrodes the pump and heat exchanger. The EVOH layer, the EN 1264-4 limit, crosslinking minima and ISO 10508 classes.

The letters record how the polyethylene was cross-linked, not a quality grade. The three methods compared, with the minimum degree of cross-linking each must clear, plus fittings and cost.

The loop pipe is the one part you cannot replace without breaking concrete. Cross-linking minimums, the DIN 4726 oxygen barrier limit, ISO 10508 Class 4, sizing and six specification errors.

Yes, but only in three narrow cases. A decision table by configuration, the loop length and floor area one circuit can cover, and the four functions you lose without a manifold.

What to fix before you send a manifold RFQ into the Gulf: a 15-line specification table, the G / R / Rp / NPT thread codes, and which conformity scheme each Gulf state runs.

The mixing valve setting is a calculation, not a preference: flow temperature bands by floor build-up, the EN 1264 / ISO 11855 surface limits that cap every setting, and the ISO 10508 pipe class.

Pitch sets the output, loop length sets the flow. Spacing by room type, loop length by pipe diameter, area per loop worked from the pitch arithmetic, the pipe take-off and six errors that surface after the screed.
