Quick question for those in the game.Having old back boiler and tanks taken out and a new Vaillant fitted in the airing cupboard where the old hot water cylinder lived.Also having all eight radiators replaced and TRVs fitted.Been told that the system only needs cleaner adding and then emptying,no powerflush required,Is this correct as I've read Vaillant specify a powerflush to warrant the system for five years.Installer is on thier site as a approved installer.Thanks in advance for any assistance.
