One for Potty people

[ChrisR]

Ought to know this myself by now: What's the difference between the Suprima L range and the non-"L" range? They look the same but have many different parts. Were there far more of one than the other?

When Part L came in about 2001 i think it meant the boilers had to be slightly more efficient than they were only about 2-3% and to do this we had to change the fan speeds on differant models and stop them from being range rateable

The only differance parts wise are the fans and air pressure switches

Thanks Gaz. Heat exchangers are different too btw.
Are many of the "L" fans going yet? I'm stocking up and there are 5 of them...!

 

[gazthepottertonengineer]

i have never replaced one yet one of suprima stronger points

the standard air pressure switch seems to work on all of them as well to be honest

 

[ChrisR]

Never replaced an "L" fan or ANY suprima fan? Either way, blimey, I have, thoroughly worn out dry-bearing noisy ones. Not many though, I mean we aren't talking puma fans here...!

Same APS on all of them ?!!! Shame on you. SOme underpaid designer spent ages testing flow rates and you go and use any old thing which works! Which one - I'll make sure I've got one.. .?

And how is the "summer" setting achieved? That is on th earlier models which had it!

Wasn't that just the 120?
