Yes it does. Thanks a lot for all the info. Seems like you'd have the rhp directly over the flex watt. If your hot spot is in the middle of the tank wouldn't you need to put your hide there? So many variations and decisions. I'm starting to think it might be easier just to get a space heater and keep the whole room warm. Not thinking I want my office to be 80 degrees though. I'll be very interested to see what he has to say about the flexwatt. My only concern is if you don't have any belly heat how warm does it get inside the hide which is sheilding the surface from the heat of the rhp.
