You may not. It really depends on your viv and your environment.

I had my first BP in an Exo-Terra viv, which does not maintain heat or humidity very well imho. I live in NY and the temp in my home during the winter is typically 72 during the day and 66 at night. The Ultratherm UTH I had at first was able to maintain 90-92 degrees for belly heat on the warm side, but my ambient temperatures were way too low. I had to add a 60 watt CHE to maintain my ambient temps at 80-82 degrees.

So... in my situation I needed one heat source for ambient heat and another for belly heat.
