So I purchased the 120 watt reptile basics RHP tonight from craigslist. Brand new unit. Of course I didnt do enough research and I now have this installed in my new tub. The 120 watt unit is 32 inches long. My pvc enclosure is 45 inches long so this RHP covers most of the enclosure. I am playing around this evening with a thermostat on it without my snake in there. Its definitely raising temps in there.
I do think the 120 watt is way overkill for a 45 inch cage(18 height) but is this going to be an issue with a thermostat plugged in? I hope not as I am way way over budget right now. And your right, I don't think I need a uth with this setup.
