Sustainable domestic hot water production with heat pumping technologies will become the dominant energy demand in the domestic infra structure offering affordable smart storage opportunities.

2019 Workshop in Seoul

In the Seoul Intercontinental Hotel an Annex Workshop was held at 16th May 2019 to inform Korea experts about the works undertaken in the Annex and the importance for Korea to participate. Presentations were given by the Annex participants.

2019 Workshop at the ICR 2019 in Montréal

At the 25th IIR Conference a Workshop, organized by the Annex 46 on Domestic Hot Water Heat Pumps, will be held on 27th August (starting at 8.30) titled: ‘Heat Pump Water Heaters, a challenging future’. Under the Annex scenarios have been developed and an R&D Roadmap will be presented. After a number of presentations the focus will be on the discussion and interaction with experts on the question on how to go forward and on what to do.

2020 Workshop at IEA Heat Pump Conference in Jeju

At the 13th IEA Heat Pump Conference a Workshop, organized by the Annex 46 on Domestic Hot Water Heat Pumps, will be held titled ‘Modelling heat pump (and solar) water heaters’

The workshop is aiming to bring together experts in order to exchange ideas, experience, make contacts and discuss the way forward.

Call for papers for 13th IEA Heat Pump Conference

The call for abstracts is still open until 30th June 2019. Submit abstracts!

At the successful 2017 Conference in Rotterdam we received 24 papers and 2 key notes on Heat Pump Water Heaters and related technologies. This was the basis of full day of presentations on this topic. We expect to get more!

Working together with other Annexes

It is of great importance to work together with othe HPT Annexes and Annexes or Tasks from other TCP’s.

At the recent 2018 – Sixth Working Meeting in Buchs – Switzerland, prof. Carsten Wemhöner, the Operating Agent from HPT-Annex 49 on nearly Zero Energy Buildings, was present, as well as the chairman for the HPT-ExCo Stephan Renz. In his presentation “Heat pumps for nearly Zero Energy Buildings – Design and integration”, Wemhöner showed us in a number of practical cases the importance of a good design of the Domestic Hot Water Heat Pump integrated in the energy systems of nZEB’s.
