I think I'm familiar with that particular kit... and yes... it will work fine.. but probably will need a CHE (ceramic heat emiter) along with the heat pad. Those heat pads are extremely small (and most of the time short lived)... keep an eye on it, and you may want to wire a thermostat or rheostat to it to control it as it gets a tad on the warm side for BPs. You'll also need a second hide... there should be one on the cool side, and one on the warm side... preferably identical hides so that it doesn't favor one hide over the other... (sacrificing comfort/security for warmth, visa-versa).
Good luck on the new snakey!
