The easiest way for a homeowner to check their likely corrosion ie sludge is when radiators are on there's cold.spots at the bottom of the radiator

A plumber could then do a water quality test to confirm and visually show you the quality of your water in the heating system"

"You should check Radiators stay partly cold
You should check boiler make noises
You should check any leakage if the pressure keep going down"

"All systems have some corrosion, we use an inhibitor in the system water to reduce this. However if you have excessive corrosion you will have black or dark system water in the radiators and reduced performance. Perhaps even cold spots in the middle bottom area of some rads..
Extreme corrosion stops the system from circulating but is not very common mostly due to inhibitor.
A magnet should not be attracted to any of the pipes (copper or plastic) if you find any attraction its because rust has settled and partially filled those pipes. Try a strong magnet on low down horizontal pipes. If the magnet sticks to areas on a copper or plastic pipe the the pipe is partly or fully blocked with rust and you need a powerflush with a machine and chemicals to resolve."

"Radiators may not warm up quickly or have cold spots."
