Objective

The objective of the Annex is to analyse the information on hot water heat pumping technologies for the production of sanitary hot water in domestic and other applications. This information will be structured in such a way that leads to better understanding in the market by the end user and policy maker.

The work under the Annex will provide deeper insight into the potential of applying domestic hot water heat pumps using various concepts and systems for new as well as existing buildings by:

  • Reviewing available domestic hot water heat pumps and combined heat pumps making hot water next to space heating and cooling.
  • Reviewing the different systems for domestic hot water in their traditional and potential applications and gaining deeper insight in to the use of domestic hot water in order to create a solid basis for test and standardisation procedures.
  • Developing and validating models to enable an objective comparison of domestic hot water heat pumping technologies and other systems.
  • Making an overview of R&D, and sketching a scenario on the needed R&D. This information will be provided to industry players, institutes, and governments with the goal of achieving simple and low-cost solutions.
  • Data basing and monitoring example projects to inform stakeholders of the viability of concepts.
  • Creating a web based information platform to serve countries participating in the Annex by publishing information on their market, legislation and policy.
  • Holding regular workshops

Project manager and participating countries

Japan,  South Korea, United States, Canada, France, Switzerland and UK. Netherlands is Operating Agent.

The Annex is not open for new participants anymore.

Activities

The Annex has been structured into the following tasks:

  • Task 1. Market overview, barriers for application
  • Task 2. Systems and concepts in comparison to alternatives
  • Task 3. Modelling calculation and economic models
  • Task 4. R&D
  • Task 5. Example projects and monitoring
  • Task 6. Communication and training

Publication and result

The deliverables of the Annex, which will be only available for the participants in the Annex, are:

  • Country reports on the state of art, the policy and the scenario’s for future developments
  • A reference guide describing presently available domestic hot water heat pumps and systems; software tools, their application and users experience.
  • An objective calculation model for comparison of the real energy performance of the different hot water systems in the market, in order to make the right choices for newly built systems and for renovation
  • Models usable for optimisation of domestic hot water heat pump technology and for the use in standards for built energy performance calculations.
  • Insight in real performances and use of domestic hot water as input for standards and calculation models
  • An online database of available technologies, components, materials, and R&D on domestic hot water heat pumps.
  • An Internet website, giving up-to-date information for the Annex participants on: market overview with possible applications and examples of demonstration projects or cases; tools for the sizing of domestic hot water heat pumps and calculating their energy and economic performances; good practice guide evaluating the users experience in different projects.

The final Annex report will be available for general publication by 2019.
