Flomasta Central Heating Cleaner 500ml is rated 4.6 out of 5 by 10.
Rated 5 out of 5 by from Central Heating System cleaner Good for small systems. Started to make a difference after about an hour of adding to the system. Need to run for a few days and then I will power flush the system and fill again and add a protection additive to the system

Rated 5 out of 5 by from Great - Recommended Our central heating was pretty much useless - but after we'd fitted a filter and by using the cleaner in it's transformed the heating system We've a big system therefore I'd recommend putting a few bottles in and keep draining your filter once a week to check on the colour of the water Our system had not been cleaned in 15 years - and it's taken around 3 months for the water in the system to change from thick sludge to clear water so be patient Overall though .. we are absolutely delighted at how much muck as been shifted

Rated 5 out of 5 by from fantastic stuff Incredible stuff. Even though a had a magnaclean pro 2 filter installed on my system 3 years ago, I had some sludge recently stuck in my pipework and boiler somewhere which caused my boiler to start to overheat and cut out every couple of minutes. Within 2 hours of having dosed my system with this cleaner my boiler was working perfectly and my radiators went boiling hot, definitely hotter than before when it was working.

Rated 4 out of 5 by from Cheaper than others I guess this is pretty much the same stuff as the bigger brands' system cleaners and does much the same thing. Can't actually tell, although it did produce a fair bit of mucky water out of my system so that's a good sign. In which case, being about half the price of the big names, it's great! I bought it because my local branch didn't have two bottles of any other cleaner (big system, needs a double dose) and I'm pleased I spotted it.
