I anticipate only
occasional use in evenings in early Spring / late Autumn and possibly during
mid day in winter to read the newspaper at weekends!

This may end up as a self-fulfilling prophecy. An expensive to run
heating system leading to less use. Conservatories can be used for
much of the year with some gentle additional heating, for everything
from dining and eating to ironing.

Extending the CH under
the floor in essentially an "outbuilding" could be asking for fun when
trying to track a problem wih the CH at a later date is my current thought!

A conservatory heater should be on a separate zone, which would make
it easy. Even if it isn't on a separate zone it shouldn't add much
to the difficulty of finding a problem.

Even if you don't install a wet heating system building is the ideal
time to install the pipes for one. Then if you start kicking
yourself after it is built installing one will be easier.
