Yeah, I would prefer to be able to put it right on top of the screen but there just isn't room for it. However I think this might end up working a little better in the end as far as air circulation and keeping the humidity right. I just want to make sure it's not wasted electricity/energy if it's not going to heat up enough, but in the 30-45 mins I've had it set up, I've noticed a couple degrees increase (nothing much, but I also opened the a/c vent in my room, as I had it closed before so the room didn't get freezing without the necessary heaters).
