Same with mine, cold pressure good but as you turn up the heat it plummets, have a pump driven mains shower in other bathroom thats great, shower screen dropped to bits last week hence using other bathroom and shower. Guess just need to pull my finger out and fix it
I have the 12KW Mira sport and the pressure isn't great when making hot water. Plumber recommend it though. Mine has been in 3 years. Makes good pressure when putting out tepid/cold water though.
aha that's why your called smartguy1 8)
Depends on how the cable is installed and what the length of the cable run is. 6mm cable is rated up to 47amps so would be fine providing the cable is clipped. It would require a 40 amp fuse and is highly unlikely to trip even unless used at full temp which in my experience of using showers I have never had to put one on full heat. Most houses already wired with 6mm will already have a 40 amp fuse fitted and will be fine. When I installed my electric shower, prior to part P, I had conflicting opinions given and ran 10mm cable to feed a 9.5kw shower. The shower broke (£200 Mira sport) after about 10 years, and was placed with a cheaper Mira, similar to the one posted at 10.8kw. It still has the original 40 amp fuse fitted and never tripped.
I have a mira sport and the pressures awful, house just bought and never had an electric shower before, is poor pressure to be exoected
