Abstract

Des appareils et des méthodes sont proposés pour compenser la réduction à haute altitude de la capacité de chauffage dun appareil de chauffage au gaz, à titre illustratif un four de chauffage au gaz. Dans un mode de réalisation représentatif de tels appareils et de telles méthodes, la pression régulée de la soupape à gaz du four et les vitesses de ses ventilateurs dair de combustion et intérieurs sont augmentées de manière coordonnée pour permettre au four de produire une puissance de chauffage maximale sensiblement inchangée malgré une nouvelle altitude plus élevée.
