Learning Objectives

The objective is to present the final report on the work done under the HPT-Annex 46 on Domestic Hot Water Heat Pumps. Based upon scenarios on future developments an R&D Roadmap will be presented challenging experts for further work.

The HPT Annex 46 ( focuses on increasing the knowledge on hot water heat pumps, as these are becoming with the lower energy use for space heating the dominant energy factor in domestic buildings. Scenarios have been developed and an R&S Roadmap will be presents and discussed.

After Presentations will be given by 7 speakers, the focus will be on the discussion and interaction with experts on the question on how to go forward and on what to do.
