What are the pro's and con's of electric U/F heating ?

There are very few pros. Installation might be a trifle easier.

The cons are many. Underfloor heating reacts slowly and that is a
particular problem in a room where the external gains will vary
rapidly and over a large range.

Electric underfloor heating is expensive to run. There is a
particular problem if it is run on off-peak electricity and the sun
is unexpectedly strong.

I've got a
conservatory on the drawing board - bit smaller than this one and
obviously this thread is of interest.

A fan unit connected as a separate zone to existing central heating
system is ideal. It can maintain a background level of warmth. It
can be turned up if one decides to use the room and will then
rapidly warm it up. It will react rapidly to solar changes.
