A Wilo Gold RS60 is a bit over spec for my system, but would there be any problems in fitting this instead of an RS50?

I just wondered if it would be a problem in principle, but here goes:as you have told us nothing about your system............
I am not sure if my existing RS50 is performing up to par (it is running at speed 3). I could swap it out for an identical model but, having possible flow problems, I wondered if the RS60 might help (only £6 quid more). Would there be any problem with this?With nine rads and a condensing boiler the RS50 should be fine.

Thanks for noticing that! Yes, it was running at speed 3. Is it normal to run pumps at their highest speed?IIRC from your other thread, your system worked properly before your current problems started.
If the pump has failed, replace it with the same model.

The pump runs continuously while the system is switched on, and runs for about 15 minutes after it switches off. Is that called 'pump-over'?Unless you're getting pump-over, leave it on the highest speed while you're sorting your system out. Once it's all working properly you can see if it would be ok on speed 2.
So, with 9 rads, the RS50 is working near its upper limit? If I have more bends and junctions than usual, then speed 3 might be necessary?thank you for the relevant spec.
yes a 15/50 should be ok on your system I would only specify a 15/60 over 10 rads or 3 floors
the size of system you have would normally circulate on setting 2

my installer said to me that a T-junction on the return might have the joining pipe pushed into the straight pipe a bit to far, restricting the flow
My vent pipe is behind the pump - not that it makes much difference for pumping over. The Y-Plans I have seen have it in front.Pumping over is when water is pumped up the vent pipe, and then cascades into the f&e cistern.

I have already been stung for over £250 on boiler bits!This needs checking out before replacing lots of expensive parts!
