Yes you are IMM ! :~)

I'd love IMM - for once - to address legitimate points rather than just
the usual crap. Of course he's stumped for answers given that maker's
blurb never gives the down sides either.

Most of us hate the noise produced by small ventilation systems. To move
air around quietly requires large ducts, good baffling, and slow turning
fans. And inlet and outlets not next to one another - which rules out just
using the ceiling void. All of which will use far too much useful space in
the average UK house - even if designed from scratch, as well as cost
dearly.

IMM loves combis because they get rid of the storage cylinder, header
tanks and the space they take up - but loves hot air systems which use
several times the space. Wonder who hasn't a clue?

What professional experience do you have of warm air systems? If you
have none, which is pretty clear you have none, then why do you
continually make a fool of yourself?
