I'm struggling to find any suppliers of bits for hot water cylinders, so perhaps my terminology doesn't help.
I'm looking for a 28mm indirect coil to retro-fit inside a copper hot water cylinder. Is there a special name for this item and who sells them please?
Also... I know there is a special name for this item, but I can't remember what it is
I want to add a second immersion heater flange, I think these come as a solder fitting and a split flat that sort of folds up to get one part through the hole. Again I need the proper name and a potential supplier please?
Thanks for any help given
