I doubt it's about heat removal, as I keep the room cold and use a powerful fan. Those extra heartbeats are doing something, aren't they?
My HR is lower on the trainer and has been that way since I started racing in 2006. I use a fan and the room is cool. At that time, I did not have a power meter so I could not make any power comparisons between the road and trainer.
