It has to feed 17 radiators over quite a long run of pipe work and the furthest ones away are not producing the heat they should. The system is balanced and working fine
My central heating pump needs to be replaced.
The one fitted is a WILO SMART PUMP but I'm not sure this was up to the job. My system has 17 rads.
Can anyone suggest what brand, type, spec, pump I should replace it with
