Hi, I will be changing my trusty old Baxi back boiler for a combi in the next couple of weeks. I am competant to do the water side of the plumb and will employ someone to deal with gas and flue side.
I am carrying out some preparations prior to proceeding and just checking before I chop a pipe or 2.
The Radiators all run from a 15mm pipe with each spurred off in turn. The returns are congregated and appear to return to the boiler via a 22mm pipe. All pipes (very handily) go in front of the chosen location for the new boiler so diverting them will be an hour or so's work including a run off for the condensate (tank overflow)
I intend flushing through the system prior to fitment of a new boiler. What are the best additives to push through the system to preserve the radiators etc?
I have up until now removed the radiators 1 at a time annually and given them a good rinse with the garden hose but I would prefer to leave them be for a few years after the new system is fitted.
