There are two single pipe systems - one where the radiator sits on top of
the pipe and would be connected via T pieces, and the other where the

It's the latter that I'm interested in.

Never seen or heard of this.
You couldn't turn a radiator off, for one.

Both were common in the '50s and '60's. The series type was often seen in
public buildings and schools - with cast iron pipes.

The later was often retro fitted in the '60's as a package. A house I work
on has this. It isn't great - but not worth changing. Must have been
installed in the Wimpy house in the mid-60's.
