i brought a gainsborough e50 shower exclusive to b and q (which is bull to start with as you can buy it anywhere) after paying plumber and electrician to fit it ,, its the worst thing i have ever brought ,when in cold weather you need it hotter it will only come out luke warm and or the overheat pressure lights come on and the chucks out cold water ,i paid the plumber to come back as the book talks about low pressure ,he has adjusted the pressures and makes no difference ,and further in the book it states in cold weather your shower maybe just warm ,,more like bloody freezing ,,its in cold weather you want it warmer and the worst thing i brought it a while back and dont have the reciept which is not there fault but i have shelled out about 300 to have it fitted and for them to come back to adjust it and now i will have to pay again to have it removed and a different one fitted and refuse to have this model so it will be have to all be changed to around to have something else fitted and pay again i reckon with a different shower and new fitting i will be into £1000
