Bedroom window and radiator

[RestorationInsanity]

Just wondering if a bedroom is the one ok place to have long curtains with the radiator beneath the window. We don't have our heating on overnight, unless the house temp drops below 17 degrees, and the curtains would always be open in the day, so not blocking the heat. In the lounge we are moving the radiator to a different wall so we can have long curtains, but there isn't a really a suitable place to do this in the bedroom.

I had same issue and my interior designer told me to have floor length. She said She would advise against having curtains if they weren’t floor length as aesthetically at sil level they don’t look as appealing, she said she would go for roman blinds instead of chose against floor length.
