Hey I have a dumb question I can find the answer too, if you might oblige one, I think the answer is they are they are basically the same. But what's the different between an unvented direct cylinder (electric only) and an immersion heater. Here we don't see ones like the gadhill, but two ports on bottom and no need for expansion vessel. The gedhill seems a bit fancier with two elements.

The immersion heater is what is fitted in the cylinder to heat the water, gledhill make a version that has inbuilt expansion vessel in them I fitted one like 3 weeks ago.
