Your orchid is happy indoors, but nowhere near a radiator. It likes a minimum of about 15C - think of it as a lot like an African violet in its temperature needs. It likes a bright but not sunny windowsill, and it must be warm, so don't trap it between the window and the curtain.
You'll notice it's potted in bark-like "soil" - you can't put it in normal compost. Water every 2-3 weeks depending on how warm it is, and let the water run through - never let it stand in water, and never, ever get water into the crown - it will rot quickly. Feed with half-strength plant food about every 3 weeks in summer. If the place you keep it has dry air, it'll help if you put it, in a base, on top of a tray of damp pebbles.
They're actually not difficult to grow as they need little attention, and the flowers last for weeks.
Hope that covers most things - enjoy!
