Servo Warm boilers

[combo]

Hi,
Does anyone have any experience of Servo Warm Elite boilers, the condensing version. It's a boiler that I never used to come across but on this new contract I've come across a few. 3 out of 4 have had the same problem, poor combustion and a blocked Heat Ex ( the lower one )...black soot and bright green and white deposits.....spent ages trying to clean one out today with a hacksaw blade, its rock hard. Is this a common fault ? I cant get much info on them.

I thought they'd stopped trading years ago!

Best guess is that they're another boiler in disguise tbh.

I think they have, my guess is these are 8-10 years old.

Your right, its a Malvern 1020.....badged as servowarm. Apparently, servowarm are now N-power.

Used to do install work for them back in the 70s, they did use Thorn boilers at one time, thought they closed down or sold out in the 90s, drive past a house quite often in Plymouth that still has a Servowarm boiler, (The one with the twin brown flue) must be over 30 years old.
