Les fondateurs de la start-up du canton de Lucerne ont d&eacute;j&agrave; effectu&eacute; des recherches sur cette technologie pour le chauffage et l&rsquo;eau chaude dans le cadre de leur m&eacute;moire de master &agrave; la <a href=\"http:\/\/www.hslu.ch\/\" target=\"_blank\" rel=\"noopener\">Haute &eacute;cole de Lucerne<\/a>.<\/p>\n<p class=\"bodytext\">Selon un <a href=\"https:\/\/www.hslu.ch\/de-ch\/hochschule-luzern\/ueber-uns\/medien\/medienmitteilungen\/2023\/10\/10\/waermespeicher\/\" target=\"_blank\" rel=\"noopener\">communiqu&eacute;<\/a> de la haute &eacute;cole, ils ont ensuite travaill&eacute; pendant quatre ann&eacute;es suppl&eacute;mentaires &agrave; la commercialisation de leur produit, le <a href=\"https:\/\/cowa-ts.com\/wp-content\/uploads\/2023\/05\/2023_cowa_BOOSTER_Speicher_Informationsbroschuere.pdf\" target=\"_blank\" rel=\"noopener\">ballon d&rsquo;eau chaude cowa Booster<\/a>. Au cours de la derni&egrave;re saison de chauffage, il a &eacute;t&eacute; test&eacute; de mani&egrave;re intensive sur le terrain. Les tests ont montr&eacute; que la technologie cowa a permis de doubler l&rsquo;autonomie de chauffage et de r&eacute;duire de moiti&eacute; la d&eacute;pendance au r&eacute;seau &eacute;lectrique. Le ballon cowa Booster est d&eacute;sormais disponible dans le commerce. Le partenaire de distribution est l&rsquo;entreprise de technique du b&acirc;timent <a href=\"https:\/\/www.meiertobler.ch\/de\" target=\"_blank\" rel=\"noopener\">Meier Tobler<\/a>.

Nos accumulateurs de chaleur sont donc d&rsquo;autant plus performants&nbsp;&raquo;<\/p>\n<p class=\"bodytext\">Selon les informations fournies, les hydrates de sel sont contenus dans des capsules. Le r&eacute;servoir de stockage est rempli &agrave; environ 40 pour cent d&rsquo;eau de chauffage et &agrave; 60 pour cent de capsules contenant les hydrates de sel. &laquo;&nbsp;Ainsi, le r&eacute;servoir tampon cowa peut stocker deux &agrave; trois fois plus d&rsquo;&eacute;nergie qu&rsquo;un r&eacute;servoir d&rsquo;eau traditionnel de m&ecirc;me taille sans capsules&nbsp;&raquo;, explique le CRO Jan Allemann.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cowa Thermal Solutions, une start-up de la Haute \u00e9cole de Lucerne, a mis sur le march\u00e9 un accumulateur de chaleur peu encombrant pour l&rsquo;\u00e9nergie exc\u00e9dentaire provenant d&rsquo;installations photovolta\u00efques et de pompes \u00e0 chaleur.
