Reading all this, it sounds like the problem is going to be much more complicated than I was originally thinking. I was hoping not to spend a bunch of money since I essentially drained the bank buying the house, but I don't think I'm going to have much choice. Plus, I am a bit worried concidering it hasn't REALLY started to get cold yet (Wisconsin).
Before I order from Animal Plastics, the lighting in the room is pretty weak. Would you recommend getting their LED lighting option for me to switch on while I out for work every day or is that too bright for them?
Also I am a visual learner, does anyone know of a good tutorial video (or forum post) on how to install the heating system and everything I need to get? I looked on here and there's an old post from 2012 on here from The Serpant Merchant but a bunch of the key pictures must have gotten lost over time and don't show up.
I'm thinking of the T3. The rooms in the house aren't big and I think the T8 that Malum Argenteum linked would be close to hitting the door if my measurements are correct.

I could also try to see if I could fit something together like Lord Sorril mentioned, but by the sound of it Sorril gave up on glass cages likely for similar problems. Unless you all think that method would be fine too, I should probably just bite the bullet and get PVC now.
