Help Needed Increasing Heat in the Winter

[SquirmyPug]

I put the insulation on three out of the four sides of the tank and then cut out a piece to lay over the top with a circle cut out for my heat lamp. The temperature increased--only now the temp is about the same on both the warm side and the ambient side (about 80 degrees). I'm hoping overnight the warm side will increase a bit more or I'll be in the market for a little space heater.

I did end up using tape. Honestly I'm not too concerned with the aesthetic of everything as long as my bp is warm enough.

80f ambient all over should be fine as long as you have the UTH for a hot spot. If you want the cool side a little cooler than the warm side you could try removing some of the insulation from the cool side. After you do that you will probably need to turn the thermostat on the CHE up a bit to maintain 80-ish on the cool side and a little warmer on the hot side.
