I have been checking temps with some cheap digitals, thermometer gun and a digital probe. The UVB is the reptisun 10.0 t5.
Our house is almost brand new and well insulated, there are no cold drafts coming in. Im in Australia and its very cold were I am atm and her tank is staying nice and warm. It's hard to tell but she can see plenty of things from where she is, not too far away is a very large floor to ceiling window and she can definitely see me moving about the kitchen etc. Not only that but I have young kids and they have been loving sitting on a bean bag in front of her enclosure reading books to her, something they wouldn't do if they had to stand up and besides once she's used to her new home she'll be able to spend lots of time outside of her enclosure.
Thanks for the tips though
