Any plumbers answer my question?
If boiler's constantly calling for heat for either central heating OR hot water (not turned on at same time) could that be cos of sludge in the heating system? Bath water is clear no sludge in that? My mate thinks it's sludge!
What controls the call for heat? Potterton suprima (not combi) boiler & Grundfos 15-50 130 Pump.
