	Indeed.  and the ones specifically mentioned
	are embedded in a concrete slab, for heating
	purposes.  One infers they are not, here,
	insulated, either thermally or electrically.
	Concrete is a good conductor (of both
	electricity and heat).  If in contact with the ground
	(may be thermally insulated) would make a nice rf
	ground (huge area....).  My concern is that stray
	RF can ge back, via the heating system, to Other Places.

	A Really Bad Place to inject RF into the heating system
	I'd think....  Unless it were abandoned....

	In such an installation, they would be.
