The paper presents development of an experimental stand with centrally located specimen for the investigation of heating and drying processes in porous building materials. Additionally, the paper contains preliminary results of measurements which test and verify the assumed operation conditions of the stand. In order to control parameters of air which was used to heat and dry the specimen, the stand was operating in a closed loop and was equipped with several elements, i.e., the cooler (humidity condenser), fan with variable rotation speed, humidifier and heater. Moreover, the stand consisted of two square and parallel ducts with air streams which had identical parameters. This allowed for two measurements at the same time.
