A published flow against a self-cleaning mechanism
A measured saving, or nozzles that clear themselves?
These two answer different questions. One is the only rain head in this catalogue to publish a flow rate with its reference pressure. The other is the only one in the whole catalogue with a moving self-cleaning mechanism rather than a surface you rub.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
Take the WENKO if a lower hot water bill is the reason for the purchase. Under 8 l/min at 3 bar is a specification rather than a percentage, and it is the only one on this shelf you can check against your existing head.
Take the RONVIE in a hard-water house. A 28 cm face on brass fittings, with a mechanism that clears its own outlets every time the water goes off, addresses the failure that actually happens — nobody wipes the nozzles.
Because flow rises with pressure. "8 litres a minute" describes nothing on its own; "under 8 l/min at 3 bar" is a measurement you can compare against another head and against your own supply. Only one of these two publishes it.
The maker describes a rod that lifts under flow and drops when the water stops, pushing limescale out of the outlet. It is a mechanical action rather than a claim about a coating. What it also is, is a moving part inside a wet fitting, and no maintenance or spare is described for it.
Rain head · Ø 22.5 cm round · ABS with brass ball joint · under 8 l/min at 3 bar stated · ½ in universal · ceiling mountable
The only rain head in this hub that publishes its flow WITH the pressure — under 8 litres a minute at 3 bar — and the only one whose saving can therefore be checked.
Best for: A household that wants a measurable reduction in hot water rather than a claim about one.

Rain head · 28 cm round (11 in) · self-cleaning rod mechanism · brass nut and brass ball joint · G1/2
