Hi, we've got an ensuite bathroom which used to have a nice shower until the pump froze earlier in the year which did for the seals, cracked the casing and led to water cascading through our property for just over a week (we were away).
Insurance covered the majority of the damage though not the cause of the escape of water - the pump itself - so we've left sorting that until last!
Anyway enought of the woes! What I was after was advice on replacement - I'd like to have a rough idea of what I'm talking about before getting people in to do quotes etc.
Our house has gravity fed system with 2 x 36 gallon cold tanks in the loft and a large 28 gallon hot water cylinder (over night Econ7). These fed a Stu Turner 4.0 bar twin imp pump. Looking at website you could pump a small village with that thing - but I think reason it was 4.0 bar was prev. owners had 1 overhead and 4 bodyjets (a lovely bespoke job ). The ST pump was actually some distance from hot/cold tanks, was overhead the ensuite in loft and fed by 22mm piping.
I've been looking at the Grohe Grohtherm Wireless options - elsewhere on forums there are favourable comments regarding these.
I'm assuming I'll need pumped thermostatic version here (given gravity fed/loft tank system) - pressure needs to be between 0.1-1.0bar?

Other questions i had were:
Any advice on siting these - the Stu Turners were meant to be as close to hot water as possible (though ours wasn't). However, the Grohe ones don't mention this?
Loft would be ideal but am slightly nervous after previous experience! Can these be 'boxed' in with insulation surrounding (though obviously not touching) or will this cause overheat?
Will same pipework be ok - i.e. 22mm reduced down to 15mm for inlet to the Grohe?
Is there any chance input pressure will be greater than 1.0bar? If in loft it will be above top of hot water cylinder and at about same level as bottom third of the cold water tank. There is a high pressure variety but I really don't think this is appropriate for gravity fed?
Any views/advice much appreciated!
PS: We now turn the water off when going away...
