It is an 1 / 2 greenhouse acollée under basement (cellar), a little in this style (but without passage to the house):
Given the rise in T ° and the fact that our winery remains cold, I plan to try to recover the calories from the greenhouse, cold here are the possible solutions:
1) Use air conditioning to put the hot part inside and the cold part side greenhouse. In other words: cool the greenhouse
-> Easy to set up but expensive (which we can find at 200 € now ... Long live China ...) and not possible because of the power consumption in operation.
2) Use a heat pipe, exactly on the same principle as the heat pipe used in some PCs.

-> No power consumption but to my knowledge does not exist for the general public other than for PCs. Expensive and delicate materials (calo fluid is generally sodium) and rather complex study. Is 50-60 ° C hot side a temperature compatible with a heat pipe? If you have to evaporate water the answer is obviously no ...
3) Use a "simple" cirtuit heating with 2 radiator (one side greenhouse, 1 side cellar) if possible recovery and if possible in thermosyphon (to avoid the cost of electricity).
-> Quite important work and fairly heavy investment.
Would there be other possibilities in your opinion? And what do you think of these 3 possible solutions?
Last important thing: is the game worth the candle?
Indeed, it is in winter that the system will find all its usefulness, but is that the Greenhouse will heat enough in winter. In addition the Greenhouse is acollée at home, so there is already a portion of the watts that are transmitted to the interior.
