Well, given that several of these weren't properly done in the first

The only boiler PCB I know of that has been totally redesigned is one of
the ones in a Baxi Barcelona. The replacement (well over £100) comes with
a new wiring harness since the board has different connections.

They must have been really desperate to do that.

The Glowworm Micron has recently been completely redesigned too (and
they don't have any stock). There are a few others for example the Maxol
