Pleurodeles and C.ensicauda are your best bets. Of all the Tylototriton, T.verrucosus are probably the most COLD tolerant, so I'm not sure how much heat they can take. Much data for T.verrucosus is actually based on other species. T.shanjing and T.notialis only come as far south in Thailand and Laos as they can manage by staying high up the mountains in the forest - they don't come near sea level or anywhere else constantly hot. Heat tolerance of Paramesotriton will vary. The least heat tolerant are probably the most common in the pet trade. Hypselotriton prefer it cooler, but can tolerate warmer conditions. What I've read of Neurergus is that heat is fine while they're on land, but in water it's lethal. That fits with their habitats, which are baking hot on land, but icy mountain streams to breed. I don't know the tolerances of axolotls - they're a tropical species, but Australians commonly buy chillers to maintain theirs. My most heat sensitive species go into the refrigerator. Bar fridges are cheap, moreso when you have one given as a gift and two won as prizes!
