I suppose you're
going to say that they
blow carbon monoxide all over the house, or that
flames will come shooting out of the vents ...

yes the older models could pump c/o around
the house....

Only if the heat exchangers was holed. And as the modern exchangers are
stainless steel highly unlikely.

less and less gas engineers are requalifying
to work on warm air as there is no money
in it...

A service call is a service call. The gas controls are the same as boiler
controls.

the goverment is pushing to stop the sales
of less efficiant c/h systems and this is putting
the final nail in the coffin for warm air.

Total ********!!! There are some highly efficient warm air systems. J&S
have a condensing box that fits in a conventional flue adding efficiency.

..however there are folks that like warm air.
..its possible to intall a wet ch boiler that
sources heat to a warm air unit via a
special heat exchanger...expensive
and Ive never saw one installed in
the uk ..

I have seen lots. Whole housing estates and tower blocks had Copperads
fitted. There are copper coil air handling units around, heated by boilers
which heat the cylinders too.

You really should find out something about forced air before you prattle
tripe.
