You can always use a uth, or heat tape, and use a CHE as needed to boost the ambient temps. I have several snakes that have a uth only and they’re just fine. I will put an electric heater in the room on colder winter nights. If it’s not unnaturally hot or cold your snake should be fine in most house conditions. The ambient temps in my house range from 68-78 depending on the season. As long as they have access to a temperature regulated hot spot you shouldn’t have any issues.
