Been reading along with this Robusta, and a great thread it is too!
Agree with yours and Mal's suggestions. Maybe whats needed is to try a few locations and test the outcomes.
Have you a Scace II device? Or can make one up? Other suggestion would be Temp strip on Boiler at / or below water level, plus an InfraRed temp reader, to test temp points along the way.
I can relate to where you find yourself....And what is often needed here is 2 or 3 mates a few beers one arvo, good n bad suggestions,
till Old Mate 'Boofa' comes up with the laughable
idea that is immediately jumped on by all and sundry....till ...someone pipes up and says you know that might just work ....
So in the spirit of Boofa, here is a few more suggestions....
1/ Henkel ( Loctite) have a heat conductive copper based metal repair adhesive commonly available at Auto shops.
2/ The TC looks similar to heatsnob - so may be a 'common' either 5 or 6mm dia x 1mm pitch thread. Easy to obtain either dye's to drill / cut your own thread in a piece of solid copper round. Braze this to copper plate for a greater surface area then affix to boiler as you've prev said near to but below upper water level.
3/ I reckon easiest is - take said solid copper round fitting you've just made up and braze it to the PressureStat pipe near to the take off from the boiler, whilst drilling a small hole in the pipe once brazing is done.
I take it the TC is waterproof ?
Heat rises so this is likely to be the 'highest' temp point in the machine's setup.

PS Just saying it wasn't me you might have been 'debating' the merits of a PID'ed HX all those years ago !
