Yes since they live in the Middle East usually. I keep Herc in his glass viv thing at room temperature and he has a heat pad under his house where he sleeps and one that runs the whole back of the cage. The shop tried to flog me a big old heat lamp but I wasn't sure if it would bug him, my wifes geckos hated thier heat lamp and it dried their skin out.
He seems happy enough, the mats warm the glass and he likes to flop out on his house one, I did try giving him some nice bedding and some hay to sleep in but he took it all out and dumped it in the litter corner, he prefers to flop straight on the glass. I have checked it, its nice and warm, not too hot
He will alternate during the day between his house and sleeping up against the back wall behind his wheel or if its a really hot day, on his concrete slab that I put in to help stop him filling his water bowl with woodchips and poop. The cage traps heat nicely (although it is well vented with a mesh roof and side panel) although its really cute to put a hotwater bottle against it sometimes because its warmer than the pad so he will come out and snooze next to it until it gets cooler, then he will look grumpy and go back in.
