Help fitting an Eastbrook Hurley dual fuel towel radiator

[flatiron]

Hi everyone,

I have an Eastbrook Hurley towel radiator and fitting it as a dual fuel, with pipes coming out of the wall.

I've been advised to get a T-Piece which the electrical element then fits underneath it, and then a manual valve fits into the side of the T-piece. On the other side, I've been told to get a dual fuel elbow and to then fit the other valve into.

I'm fitting manual valves and have been told to get corner ones (as opposed to angled or straight), but not sure this is right.

Can anyone tell me what pieces I need to make this fit as a dual fuel? I'm trying to get it to look like the dual fuel one this picture at the bottom, but using manual valves not TRVs.

Thanks!
