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.

Thanks David - headache will be that this is a traditional Scots farm
cottage and you will know how thick the walls are - and are usually
rubble in the middle so drilling holes for pipes is a bit of a
nightmare. Might have to think about microbore along the skirting.
