Hi all, been helping out a guy who's put a solid fuel boiler in his kitchen and want's to link it to his oil boiler - found him a link up system but not being any great solid fuel expert (and I told him this) have found we need to change over to a gravity system and install a gravity F&E tank but found out this needs to be made of copper plus the ball valve and the overflow and the expansion pipe - no problem found a supplier who can do that. Now the question is -- does the rest of the heating system ie all the house rads/cylinder primaries have to have copper pipe too because at the moment there not (owner put his own system in hep20). My gut feeling and after looking at the link up layout it will have to be, as when the boiler is up to full heat and the heat leak in the loft can take no more the panel "dumps" the heat to the system A second opinion would really be appreciated from someone who knows more than I do about installing these types of boilers - can't get a reply from link manu as on holiday... ps. told the guy he should have got Hetas in to do it but it's too late he's already done it
