Rated 4 out of 5 by from Better than the rest I have one blocked radiator on a 15 rad system and had already tried fernox f3 and sentinal x400, neither of which had any affect, tied of the draining of the system I used this central heating system cleaner as it didn't need to be flushed out like the other cleaners and whilst it didn't fully clear the blockage it did make a noticeable improvement after 4 or5 days. I plan to treat the system again when the item is back in stock and hopefully completely clear the issue
