Salus auto balancing actuators….. on manifolded rads

[HughF]

I’m proposing manifolding my new rad installation for various reasons (mostly I don’t like hidden fittings) and that got me thinking, would I be mad to ditch the lock shield at the rad and just throw a salus self balancing actuator on each manifold port?

 

They’re programmed for dT7, which would be spot on for my ashp install.

Dt7 is for a flow temperature over 30 degs, then dt4 below that.

 

Would make the job of balancing easy.

One less thing for meddling fingers to fiddle with too.... the rad circuit is being sized for 45 degree flow (I'm already unpopular with the rad sizing at that temp) so dT7 it is then. I didn't know they auto switched to dT4 below 30. What a genius device.

In order to apply a blanket dT across all radiators, doesn't it assume that each radiator is perfectly sized for the room it's fitted in? Similar to UFH pipe spacing etc. Otherwise won't you risk having a dT 4 or 7, depending on the flow temp, but that not resulting in a comfortable room temp?
