I've installed various undersink water heaters, mainly 3kw=15litres.
They come with 2 plastic(or similar) connectors which connect the 2 1/2'' fittings on heater to the flexy's im using.
The destructions say they are DIELECTRIC JUNCTIONS?

What is the reason for these? I,ve bought a couple of heaters of e-bay and the dielectric junc. are missing.

Who sells them? Part cen? Hargrieves? Screwfix? or toolstation?

they prevent an electrolytic reaction.

Probably have to get them from the manufacturer

They are designed to keep 'dissimilar metals' apart and keep corrosion problems to a minimum. If you are connecting the units by normal flexy's I wouldn't bother to much about it.
