Keeping Pythons at room temps can be done however I only recommend it for experienced keeper and even in that case the ambient temp of the room where the snake is kept should be in the mid 80's/
As far s UTH for stand alone enclosure I am partial to Ultratherm they are sturdy, and do not stick to the enclosure like other brands do (making it hard to tranfer them to another enclosure if you had to.)
