For one rad it isn't necessary, but you should add another dose every couple of years ideally anyway. Use Fernox, Sentinel, Aqueous Logic, Kamco,... ie not a very cheap one.

Dear ChrisR
I wondered if you worked near Wimbledon as I need a new combi boiler in the next couple of weeks before a kitchen is put in which starts on May 21st. Someone else on this site recommended you but I do not know how to obtain your email address from the profile. Carrie.
