If it is a gunk problem then a quick flush and proper inhibitor should resolve it. First I would balance the flow/heat output of your radiators. That should compensate for moderate gunk problems or show if there is a serious gunk problem. The general advice is for a filter close to the boiler on the return side, so avoiding carpentry in your cellar.

Is your boiler down low or up high?
Out boiler is in the loft and the return, uphill, side of the house has cold radiators. I am told it is due to gunk collecting at the bottom of the loop and robbing heat from the water.
I need to install a filter apparently, but that means ripping out the carpentry in my cellar.
