The Micro-cogeneration and Emission Control and Related
Micro-cogeneration devices are used to meet both electrical requirements and heat demands (for space heating and/or hot water production) of a building; they can be also combined with small-scale thermally fed or mechanically/electrically driven cooling systems. Many micro-cogeneration units are already commercialized in different countries
Chaudière à micro-cogénération : tout ce qu''il faut savoir
Tout d''abord, avec une chaudière à micro-cogénération, plus on produit de chaleur, plus on génère d''électricité. Elle est donc plutôt adaptée aux logements dont les besoins thermiques sont importants.. Ensuite, sachez qu''une chaudière avec un moteur Stirling fonctionnant au gaz ne prend pas plus d''espace qu''une chaudière à condensation classique et s''installe sur un mur.
