I use mostly rhps bc of my house staying between 60-65 all year long but for the one PVC cage that I can't put a rhp in I have 2 heat mats, I have one that's 1/3 of the cage set for 92 under substrate and the other is the rest of the 2/3 of the cage set for 82 under substrate. Another one of my snakes was kept the same way but then I switched him to a rhp and now that's all I use for cages but I have had zero issues keeping snakes using 2 heat mats.
