Well, this is something I have done since I have been keeping worm bins indoors in A/C. The middle of the compost pile is noticeably warmer. It's like running your hand in very warm water, you know it's a lot warmer, but it's not scolding hot. I would guestimate it at about 95 degrees Fahrenheit with an ambient indoor temperature of 75. We are talking about things on a very small scale, and I don't have the background in Biology to even guess at the implications of implementing this design. I think experimental observations may be required

Although I will say this, with a very large system it is clearly possible. However, the feasibility of maintaining such a large system may not be possible, but that would obviously depend on your situation.
