Can anyone help me identify this system?

Went to apartments with this set up. It's got an 18l expansion vessel. To pipes out the top. 2 central immersions going into the fuse board on the front. A pipe coming out midway with a grunfoss pump then goes back into cylinder. 1 pipe with pump(central heating) going into it.

There's a 2 channel programmer. It can't see any zone valves anywhere? Anyone familiar with this?

Looks like an electric thermal store.
Hit wTer goes through a coil and heating is pumped direct from the cyl.
Is there a header tank on the top?

Not a Church Hill set-up is it? I'm sure someone else posted about one of these this week....
