Shaun, I have referred to the manufacturers manual. The existing set up is as per the diagram in the manual except for pipe sizes. The set up for a fully pumped system is the usual pump + MV with the F/E and vent connected to the boiler. The purpose of my post was to enquire if other people had any experience of twin pump systems. I understand that these were popular some years ago and presumably used with the older cast iron boilers such as the one on the installation I am working on.
Many thanks for your reply and for the other very interesting posts you provide to other enquirers.
