Rated 4 out of 5 by from Simples! Easy enough for the home DIY'er to apply to header tank after draining the system, let it work, refill and redrain. Unfortunately it was too late for me to avoid a new pump install but have Fernox f1 inhibiter to put in the tank to help prevent future clog ups.

Rated 5 out of 5 by from Superb Cleaner I've had an extremely noisy heating system for the last year, put one bottle in and no result. drained down and put three bottles in, no result for three days and I finally slept through heating coming on in the morning. Brilliant product would recommend it to anyone.

Rated 5 out of 5 by from Good Cleaner I was surprised how clear the water was when I drained the system for the first time in years to change a valve. However, after running the system overnight with the cleaner I was pleased to see some discolouration when I drained the system for the 2nd time.
