Do any of you have warm conservatory? How?

[Nochristmasbreak]

I love my conservatory but it's ice cold in winter, despite a radiator.

What would be best to warm it up?

Putting a roof on it? (And blocking out the lovely light)

Under floor heating?

Adding blinds all the way around? (again blocking out the light)

Adding another radiator?

@TrickyD thank you! Sorry for all the questions. But is your underfloor heating electric or run off the existing radiators?

It is electric and is independent of any radiators. . I think a water filled system may well be cheaper to run but dearer to install. It does work very well as there are no cold spots.
