Well I posted some pics of Clifford and his house yesterday in Introductions. Here are some more. I took a rubbermaid shed, cut a door and filled the open gaps with foam in a can. I used carpet runner for the door and cut 4" slits. I used Reflectix insulation along the walls to keep the warmth in. The heat is a 150W CHE which hangs from the roof. I also placed an inside/outside wireless thermostat to keep an eye on the temp inside the enclosure while I'm in the house. So far so good. Last night it got down to the low 40's and the inside of his house stayed a warm 74. I plan on getting a Kane or Stanfield heat mat to keep him a little warmer during the colder months. I live in South Texas and it's rare that it gets below freezing. Anything below 30 I bring him inside our house anyways. Any comments or suggestions are appreciated.
