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.)
