The municipality of Varzy wants to set up a second district heating network. It will run on wood, an abundant and competitive local resource. Varzy gathers in a limited perimeter many communal buildings (town hall, museum, associated housing, schools, gymnasium), buildings of the departmental council (the college and its boarding school), the Region (ironworks high school) as well as permanent consumers of heat, in particular the EHPAD . This configuration is very conducive to the establishment of a district heating network. Installation of 3 biomass boilers of 300 kW or total wood power of 900 kW (gas backup for 1800 kW)
