Terran tu te trompe quand tu dit
non isolé au fond ni sur les côtés, seulement recouvert d'une couche de sable de 30cm
ce stockage est isolé avec 200mm d' XPS (polyst.. extrudé) sur le dessus
et isolé (insulation) aussi sur les côtés (épaisseur et matière non précisé)
Je commence à prendre de l'âge, la comprenette ralentit, les idées nouvelles deviennent rares. Donc, quand par chance j'en tiens une, je m'y accroche.
J'ai donc envoyé un mail dans un Anglais très approximatif à une des sociétés impliquée dans ce projet Canadien.
Je vous joins ci-dessous ma question et la réponse.
Hello,
I am very interested in your interseasonal solar calories storage. Unfortunately it seems more difficult to realize for an individual house.
May have I a question concerning the "Borehole Thermal Energy Storage" insulation?
I understood that it is insulated on the superior part with 200mm XPS and 300mm graded sand.
But I don't understand if the sides and the bottom of the BTES are also insulated.
When I read " Outer edge of sand fill, insulation and polyethylene sheet " under the drawing of the BTES, I am overcome by doubt.
As I am not familiar with English language, I am not sure that "Outer edge" refers to the sides or the upper of the BTES.
I am convinced that insulation of sides and bottom is, by far, a more expensive and complicated solution.
Could you tell me what solution was used.
Thanks in advance.

Hello Pierre,
Florin is not working at Enerworks anymore. I am somewhat familiar with this project and you are correct that the only insulation is on the top of the BTES storage area. No side insulation was used as the cost would be too much when compared with the potential gain. I hope this helps.
