Where near Sofia do you live. During my childhood in Sofia such exotic plants would have been impossible to obtain.

about 30 km from sofia, in a mountainous area, 830 m above sea level. Well there are sellers in our country, who happen to cary exotic stuff in summer, also there are the some people, who grow such species and sell them, mostly seed germinated plants, once in a while i do happen to find a species i have been searching for a long time.
Yes those tipes of plants do not grow outside anywhere in BG , you have to go to the botanical gardens or people's personal collections, to see them.
Drymifolia, my gh base has insulation on the concreete , on both sides, that does help alot. It is also not atached to the house, but rather one meter from the wall. But yes , the place where it is located is somewhat wind protected, and is kinda a sheltered location overall.
I would not reccomed wood stoves for greenhouses, too much maintenance and also could be a fire hazard. I was using one the first winter, the chimney catched fire a few times, i had to monitor the fire closely each evening, resulting in me staying regularly up to 1- 2 am, in order to be sure the fire wont die off, a single mistace is all it takes for a collection to be lost. BUT i did have a very small gh and also plants closeby enough to be fried from the heat, i quess in a much bigger gh, the wood stove wouldn't be such a pain...
All the fruit:
Thank you all very much for the professional advice. Also Platinium, can i visit your collection when i go home some of those years?
Also i would be happy about more suggestions what they can plant there that does not grow outdoors in Germany

Zone 8...almost any thing. You only need to stay above 50 degrees F and almost any thing will survive. Not thrive but survive until spring. Citrus will work. White Sapote will work. Sapodilla will work. Mamey will work. Custard apple will work. Abiu will work. Babados cherry will work. You have to seal it well and you have to make sure you have enough compost stored inside.

It would take an impossible amount of compost to heat a 20,000 sq ft glass single-pane greenhouse above 50°F in 8a Germany. I mean by all means start by putting in a large compost pile and add a temperature sensor, but Germany is more like Seattle than an east coast 8a in North America: cold and overcast for much of the winter. When it's overcast and the outside high is in the low 40s°F with freezing lows every night for months on end, there's no way compost will work to heat it that much.
Look at the average low and high in winter, it's not like the zone 8 in the Carolinas:

You might be right. My thought was definitely bases on my Carolina experience and the fact that 32 at night but 40 to 50 in the day. I can get well into the 70's in my hoop house on a 40 degree day. The temp inside may get into the 30's for a short amount of time but most of my plants have withstood it.
