[QUOTE="Evans Electric, post: 26317, member: 1408"] Only just seen this one . I tend not to rely on res.reading on immersions , if they are backed up by a rewirable fuse and no RCD they tend not to blow. Heaters will split open in the water and even just two prongs, the rest having dropped off, still working but not very hot. Megger it to earth and /or try your clamp meter to see if the current matches the killowatts. Luke warm water usually means duff heater. [/QUOTE]
