Keeping snakes without a hotspot

[RAD House]

I mean to be fair our idea of thermoregulation is based off of what hobbiest have done before us. If the snake can maintain the correct temperature does it need to thermoregulate? Is this changing of temperature actually better for an animal than staying at the correct temperature all the time? I use heat pads as constant temperature isn't realistic in my home, but I may consider it if it were.
