Thanks for the effort you (and others) put in to getting these articles
together.

I feel there is some confusion in the term plug-in. I have seen quite a
few built-in electric fires (fan and bar) which in every other way are
equivalent to the plug-in models.

Back in the 60s we had a bar fire which had its heating wires within
quartz tubes. Not, I think, covered. (Are they still available? Or is
this just an historic footnote.)

I've seen what was then a quite common ceiling heat/light combo
advertised quite recently, and mentioned here. Dimplex did a very
common 750W wall mounted version too, which I haven't noticed
recently.

They are silica glass tubes, and for the purposes of PAT testing,
the silica glass is considered to be a live part (which means most
of the 60's ones won't have good enough finger guards nowadays to
stop you touching the tube).
