Very good shower. I have one. Good pressure compared to most off a combi boiler where water pressure is generally low compared to a gravity system. Beware that the height of the overhead is fixed so make sure you measure to have at least 6 inches clearance above your tallest noggin, ottherwise you'll be showering on bended knee!
There is a Mira APT ERD for £137 on ebay. It is not the same as this Mira Atom, but from a glance online, they're fairly similar. I had bought from the ebay link, new but just a damaged box ebay.co.uk/itm/Mira-Thermostatic-Shower-Mixer-Apt-ERD-Diverter-Chrome-Rear-Fed-Exposed-/383902654129?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=710-127635-2958-0
Delivers 12.14Ltr per minute at 0.5 bar • Minimum pressure: 0.1 bar • Maximum pressure: 10 bar Compatible with any water system or pressure My reading there is it’s for high pressure for expected shower performance but interesting as it does reference 0.1 bar but does not list the flow rate at that pressure. I have gravity hot around 0.1 bar (tank in loft) and mains cold in bathroom. Although the manual suggests would normally like a nominally balanced pressures I wonder if this thermostatic valve would cope?
Had this shower for about 4 years now, no dribbling, replaced head, hose and bracket for holding the shower in place, new replacement cheaper plastic compared to older model. Sure screw fix we’re selling them off last year for £100 thought about one for spares but never bothered
Had this fitted a couple of weeks ago. Very good power. Lots of cheap plastic fittings though.
