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.

A great number of new example projects have been uploaded for which the factsheets and some underlying reports can be downloaded.

Example projects in countries participating in the Annex and some other countries fall under four main categories:

These are collected for Single Family Buildings as well as Multi-Family Buildings. Only a small number of projects have been monitored.

This being only the ‘Top of the Iceberg’ it must be mentioned that next to the number of examples collected, there is a number of other sites an information platforms where examples are shown.

Workshop ‘Heat Pump Water Heaters, a challenging future

At the 25th IIR Conference ICR 2019 in Montréal on 27th August a Workshop attracting more than eighty participants. Presentations were held by experts from the participating countries in the Annex and invited speakers from Spain and Sweden. The presentations and relevant papers published by the presenters are available on this website under the publication pages.
