[QUOTE="Evans Electric, post: 490493, member: 1408"] Don't bother with the EICR ...concentrate on the tripping problem . First thing to do is to run tests on the RCD to ensure it's not "Nuisance " tripping . Then identify the level of current flowing to earth across ALL those circuits protected. I see from your picture you have two circuits switched out ( That garden pump could have been high on the list !) Then you have no less than five ring mains PLUS the UFH to check . All need to be ruled out . I think there may be some earth leakage / damp , on your heating mats when cold ..possibly... which disappears when warm ... insulation readings when COLD , then WARM will be interesting . [/QUOTE]
