Rated 4 out of 5 by Sealed system inhibitor Only recently started using this for sealed system and it's great. A bit pricey though. 16 Jan 2016
Rated 5 out of 5 by Great product. Unbelievably easy to use if you have a filling loop as I did. It was so quick to do that I thought it hadn't gone in at first, but the can had gone ice cold so it obviously had! 28 Oct 2015
Rated 5 out of 5 by Super easy. Really good product, coming from Fernox you know it's good quality. This product is so simple to use and the contents of the can are fed into the heating system really quickly. I used it via the filling loop, but there's also an adaptor to fil via a radiator. 1 Oct 2015
Rated 5 out of 5 by Great Stuff Without doubt a very easy way add inhibitor to my central heating system. Just connect to the pipe at the boiler, job done! I used the same product last year and when installing a new radiator in my home the drained water was clean with no sign of corrosion. Will certainly buy again. 20 Jul 2015
