Hi everyone
Looking for some advice please
I have Worcester Bosch green star 38cdi classic HB combi boiler.
It’s only a few years old and has a magni clean thingy fitted to collect the metal etc.
I have bled all radiators most rads bar 2 small ones 400mm x 400mm (old) are all brand new 2 panel 1 convector, all pipe work is 15mm no microbore
The upstairs rads get extremely hot almost too hot too touch, most the downstairs ones do as well apart from about 3 - I have turned all locksheilds down to virtually off about a quarter a turn open and these still get red hot. This improved the downstairs ones that were cool but still hasn’t solved the issue. Im wondering if I need a bigger pump fitted?
The rads have been taken off and flushed out there is no sludge issue here the boiler is only about 4 years old.
Does anyone have any suggestions or what it may be.
Thanks in advance
