Hello all
Need help, or at least guidance
My circulation pump on my boiler is knackered and I need a new pump head.
The marking on it states "GRUNDFOS UP 15-50 AO B/BC" followed by a part number (59945503)
Looking around the net I can find many Grundfos 15/50 pumps but they are nearly all UPS, not UP
Does anyone know the difference as to what these two abbreviations mean ?
As a 'very' rough guess, are the UPS pumps selectable speed ?
In essence, I need to know whether of not it matters between buying a UPS or a UP type pump - are they at all interchangable.
My system is a Vokera Compact powering DHW & 5 radiators
Thanks in advance, any guidance / help / suggestions appreciated
