Advice on how to heat a conservatory? Under floor heating?

[Whatsthispain]

Hi. Our conservatory is now finished and we need to decide how to heat it. Would under floor heating be a good idea? Is it cheap? We're under no illusions about keeping it warm long term, but need it warmed up whilst we're in there. Dh says there's a wall mounted blower that can blow hot or cold air? We could get a fake electric log burner fire? What would you advise? Many thanks.

You can get radiant heaters, basically like a patio heater.
You can't really heat the room with them, you heat the people and objects, but in a conservatory it's pretty much outside with all those panes of glass so having anything more substantial would just be sending the heat outside
