i am going to replace my Heating circulator as the Wilo Gold has become very noisy and vibrates through the whole system.
upstairs my rads are on 15mm pipe i believe without measuring, but downstairs they are on microbore pipe. i have been told that a standard pump may struggle with the resistance of microbore and so i should buy for example the Grundfos superselectric as opposed to the selectric. (15/60 instead of 15/50) is this correct? or will a normal 15/50 selectric handle it ok?
i only have 7 rads in all. 4 up and 3 down on microbore.
