Purchasing a new UTH and Thermostat

[Evenstar]

I prefer my uth to be slightly smaller than the "warm side". This creates a central hotspot but the warmth does spread beyond the actual pad. My uth is also right at the end of the enclosure - not centered on the warm side. The hide box on that side is directly over the uth. Placing it at the end seems to create a better thermal gradient.

I also recommend Reptile Basic's Ultratherm UTH. ZooMed's are ok, but the Ultratherm is far superior and the price is the same or better. I use both so I'm speaking from experience.

You also need a thermometer so you'll KNOW what your temps and humidity are. The Accurite is terrific - it measures both the warm side and the cool side and humidity too. About $12 online or at Walmart. Accurite

Hope this helps!
