In low-temperature boilers in heating installations with a high heating capacity, i.e. with a large water content or storage volume, a great deal of condensate arises below certain boiler water temperatures, which does not evaporate fully in the case of conventional operation. To limit the amount of condensation and to eliminate completely the condensate created, the return run temperature is raised after a fixed time span by adding forward run water and the desired temperature is increased in the event of the stipulated desired temperature of the boiler water not being reached.
