Installation for central heating and/or production of hot water for sanitary or industrial purposes in which there is recovered on the evaporators of heat-pump circuits the enthalpy of smoke coming from the boiler and from outside air introduced into the installation through air inlets. Before being brought to the evaporators, the smoke is possibly cooled, however without being brought to dew point, and the heat thus produced in an exchange circuit is recovered for reheating, before its discharge into the atmosphere, of the smoke and outside air mixture so as to recreate a chimney effect, the gases discharged being hot and dry.
