Furnace (100) for heat-treating annealing material (102), wherein the furnace (100) comprises a sealable first furnace chamber (104) designed to receive and heat-treat annealing material (102) by thermal interaction of the annealing material (102) with a heatable or coolable first annealing gas (112) in the first furnace chamber (104), a first heat exchanger (108) which is arranged in the first furnace chamber (104) and is designed to exchange heat between the first annealing gas (112) and a transport fluid (116), wherein the first heat exchanger (108) is arranged within a housing section (120) of the first furnace chamber (104), which housing section (120) encloses the first annealing gas (112) inside the first furnace chamber (104), a sealable second furnace chamber (106) designed to receive and heat-treat annealing material (102) by thermal interaction of the annealing material (102) with a heatable or coolable second annealing gas (114) in the second furnace chamber (106), a second heat exchanger (110) which is arranged in the second furnace chamber (106) and is designed to exchange heat between the second annealing gas (114) and the transport fluid (116), wherein the second heat exchanger (110) is arranged within a housing section (122) of the second furnace chamber (106), which housing section (122) encloses the second annealing gas (114) inside the second furnace chamber (106), and a closed transport fluid path (118) which is operatively connected to the first heat exchanger (108) and to the second heat exchanger (110) in such a manner that thermal energy can be transferred between the first annealing gas (112) and the second annealing gas (114) via the transport fluid (116).
