This time, we met among all HEETII project consortium members during the scientific conference KOMTECH 2022, in Szczyrk, Poland. The progress of WP3, WP4 and WP5 was presented. We are moving towards the completion of the prototype construction, launching the first tests and trials, collecting data and analysing them. In addition, the conference included a number of presentations on the current results of the project HEETII.
