I have a 4x2x15". Also live in New York, and the room where my snakes are gets to as low as 65. I only use an RHP, and have absolutely no issues with heat. I know yours is a little taller, but I think an RHP would work great that. And... if you add levels (branches, shelf's, etc) you can also vary the vertical gradient a bit.
Thank you so much! What wattage do you use? I’ve got lots of branches and ledges to offer some climbing options, so that’s definitely in the plan.
