[QUOTE="batty, post: 35851, member: 66"] Mr S. they certainly are not easy to find on heating systems. I got called out to one a few weeks back. It was blowing the 5 amp fuse (oil boiler) as soon as you turned spur on. Insulation resistance was about 20meg. Boiler man was there but I could not figure it out as 20meg was not enough to blow fuse I thought any way he changed a part on boiler and this seemed to cure it but what I could not understand was why fuse went before boiler fired anyway have not been called back so assume this was what problem was.
