Offers and wants: Schott 'through-flow' evac tubes (approx 20) available
South Yorkshire Energy Centre, in Sheffield, is having another clear-out (of things I have squirrelled away over the years!). They have about 20 Schott evac tubes available, with manifolds (and indeed the remnants of the broken ones as I can't see how to get them out!). These are not the heat-pipe type. The water/anti-freeze flows through each tube, so one failure and the whole system fails. In our vandal-prone location this was not ideal, so they got replaced.
I do not know at this stage how much they want for them, but if anyone is interested, please let me know and I'll pass on your interest.
