Think it very much depends on the age of the unit - and how well the
installation was done.

It's a fairly new unit, replaced within the last 5 years, in a house we
might purchase (designed around this type of system).
The neighbour thinks it's great, but a friend of mine thinks warm air
heating is ****** ****** or worse.

old - and it's not great. I'm currently thinking about putting in a
wet system before it finally gives up the ghost. Apart from the
inefficiency of my old system, I would say the problems are incomplete
coverage (ie if it's not well designed, it isn't as easy to modify as
a wet system), poor control (opening and shutting vents isn't as
simple as setting a TRV and leaving it, plus the thermostat seems to
have a mind of its own, although that could just be my one), sound
transmission around the house through the ducting, inflexibility when
it comes to furniture positions (if radiators get in the way here,
remember that you need a clear path from the vent into the room) and
an overly dry dusty atmosphere. In terms of capital cost, should the
main unit fail, you can install an entire wet system for less than a
direct boiler replacement.
The positives are a fast warm up (but an equally fast cool down) and
the ability to circulate unheated air when the weather is very warm
(should that ever occur again this summer!). I am toying with the
idea of changing to a wet system, but keeping the vents and installing
a decent fan for a sort of pseudo air con system, although I haven't
found a suitable fan yet....
I hope that helps. In the end, I should think it's neither as bad or
as good as some people would tell you. One thing's certain though -
nobody wants to buy your house once they notice it, and that's what
will drive my change.

Thanks folks, yes, i'm quite prepared to have a wet system installed if
necessary.
The house we might purchase is actually a bungalow so i'd expect the
pipework would be very obtrusive, sadly.

I rented a house with one -- the whole estate had been built
with them in every house. Don't recall what make it was though.
I quite liked it -- the fast warm up was great if you don't
have predictable occupancy times which suite a timeswitch.
Others in the house didn't like it -- got problems with the
dryness it caused making peoples' throats dry and irritating
contact lenses. None of us smoked, but that would have been
a complete disaster. Only rooms abutting the central air
plenum got heating, so the bathroom and third bedroom didn't.
It's well beyond the average householder to work out how to
balance the register plates so all the hot air doesn't just
go into one room (just like you wouldn't expect them to be
able to balance a radiator system, but they are expected to
be able to balance a warm air system). Even just opening or
closing doors can have a dramatic effect. We were one of the
very few houses on the estate which hadn't had the system
replaced with radiators, and they weren't old enough to have
worn out, so that's probably the best indication you can get
of what most people thought of them.
