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

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.

A wiring centre reconciles thermostats, actuator heads, the pump and the heat source at the manifold. A full terminal schedule, the channel-versus-loop counting problem, and the six wiring faults behind most commissioning callbacks.

A thermostat is chosen by switching voltage, output type, sensor configuration and back-box fit — not by its display. The selection table, why actuator starting current welds contacts, and the floor surface-temperature limits that set the probe.

Which manifold body belongs in your warehouse? Stainless steel and brass compared on corrosion, accessory fit and landed cost — plus the alloy designations to name in a purchase order and why CW617N is not a low-lead grade.
