Heating unit question

So are heat panels any good? I am considering using one to heat a large DIY cage for a future emerald tree boa. Or am I better off with a UTH and/or lamp. This would remove the need for a screen top- my room is kept pretty cold so a UTH+Thermostat probably won't cut it. Or maybe Heat panel + UTH?

The heat panels from pro-products are amazing. They heat super efficiently and effectively. And suitable for even the highest humidity environments. They dont zap away humidity like the lamps and actually simulate the sun. Contact pro-products and they willl help you all the way. Tell them the size of the cage, ambient temp in the room, species in the cage and they can tell you what you would need. And the customer service is amazing. I HIGHLY recommend getting a panel from pro-products.
