You can get barrier or Non barrier ( black writing on non barrier and its cheaper ) Non barrier lets oxygen molecule in and the inside of rads corrodes like mad !!!!!! Blocks 10mm pipe solid , the water looks like oil !
Flushed one last Friday , luckily 15mm pipe so brought it back to life used 3 litres of inhibitor on completion but no guarantee !
Never seen it before
the evidence is black water, cold spots on radiators and my combi boiler cuts out- heating and water don't work together, so either water or heating. when its heating, it will cut off after an hour- something to do with pressure or the sludge possibly.
not new system- it came with the house, 5 yr old new build. but recently added a large radiator from an extention.
the initial problem was fixing a valve- to controll 2 independent thermostats; one for living, one for sleeping. only one thermostat communicated with the boiler so only downstairs had heat and upstairs nothing.
Sounds like you would be better off long term repiping the lot
