Experiments were performed to investigate heating up processes of fluids in storage tanks under the influence of an external heat sourec. Several teste were carried out both with heating from the bottom an with heating from the side walls. The test tank was equipped with thermocouples for measuring the temperature distriburion and with needle probes for measuring of the local void fraction.
