Compost-heated greenhouse?

I've got to keep a small greenhouse heated to about 30°F above ambient nighttime temperatures (e.g. outside is 50°F inside is 80°F.)  (Small: 10' diameter circle, 7' high.)
A compost pile is perfect for this, and it occurred to me that I could just put the compost pile under the plants.  They also want a lot of humidity so that should work out, eh?  I can put a perforated drain pipe in it to make a static aerated compost pile.  Cap the end to aerate the pile, uncap it to vent moist heated air into the greenhouse.  What do y'all think?

If you can keep the compost in perfect synch, producing good heat, it may be viable. That takes some maintenance from what I've seen.

The downsides I can see are introducing bug eggs and mold into the greenhouse environment.

I have real differences with her but this youtuber has the best compost heated greenhouse set up I've seen:

Here's the "tropical conservatory" in it's present incarnation.  As you can see, it's not that big.  I just have to keep these plants warm at night until I can build a proper insulated greenhouse for them.  I suppose could put them in the old mobile home and pipe in sun with mirrors.  There's a cast iron wood stove in there already.  Maybe I'm overthinking things again, eh?

In sync with what?

I thought hot compost kills the bug eggs?

I saw that video, it's pretty thought-provoking, eh?  It works even in winter.
