•A thermal model is set up for large anaerobic digesters with multimembrane gasholders.•The model is validated using data from one year of operation for a large biogas plant.•Changing from a single- to triple-membrane system reduced digester heat input by 52%.•Digestate heat recovery reduced heat in...
