The same method could be used for washer driers, in fact the heat
exchanger could also be used to heat water for low temperature

Unfortunately, most washer dryers use a condensing mechanism that uses a
medium sized reservoir's worth of cold mains water to condense. This
laziness in design is an environmental disaster, and a financial one to
those with water meters.

True. Another possibility for exhausting heat to the room is that by
adding a CH feed to the heat exchanger via a solenoid valve, it could
double as a kind of 'kick space' heater to heat the room when the
drier or washer/drier is not being used.

This could save on wall space for a radiator which may be at a premium
in small kitchens.
