Come on then, poke sticks lads!!

Yes they need engineers. Can't meet demand atm.

As for which ones are most problematic, well am guessing that no-one in
my dept. has the savvy to use a Usenet group so I would say avoid
Highflow 400s and CBi models (cast iron heat exchangers).

Is that the Greenstar Highflow 440?
