I agree with what Dave said. I have a few Pro-Products panels going on around 8 yrs now. Great products. However, experience with RHPs has enabled me to get whatever RHP and it works.



My last two panels I purchased from the Bean Farm. The 40-watt 11x11 size radiant heat panels.



I ordered them because I just wanted a heat panel, soon, without having to bounce emails back and forth. Conditions change, I don't need a panel fine-tuned to my cage at a given point in time. If I have a 3ft x 2ft x 1ft high cage, then a 40watt 11x11 panel is great. If I have a 4ft x 2ft x 1ft high cage, then the 11x11 panel is fine much of the year except Nov-Feb, and then I wish I had an 11x17 for those colder months. That is when I add a heat pad.



All in all, RHPs are effective heaters for larger-bodied reptiles. The panels direct heat downward and penetrate objects, just like the sun does. It can warm up a boa from the top down like a heat pad does from the bottom up. Results are the same. Gradiant is better with an RHP.



For your heat pad question, you will have to use the 20 watt/ft Flexwatt or else insulate around the cage. Otherwise, an RHP may be your better solution for a hefty snake like a boa.
