I have almost finished upgrading my c/ht system except new boiler
I have left some previous radiators and some plumbing in ,I am about to put in Sentinel x400 to remove any sludge etc,Old boiler still running ,will replace when system has been cleaned,
Do I need to put in central heating protector (fernox) at the same time as I have installed several new rads. to avoid any damage to them.
