Products and services for IoT heat pumps
Over 40 different examples of projects and products for IoT heat pumps were collected in IEA HPT Annex 56. A distinction can be made between 5 categories: Optimization of heat pump operation, Predictive maintenance, Provision of flexibility, Commissioning of heat pump systems and Heat as a service. An example can be assigned to more than one category. The examples are available at https://heatpumpingtechnologies.org/annex56/factsheets/.

Stakeholders in the life cycle of IoT enabled heat pumps
Various examples of business models for IoT heat pumps were collected in IEA HPT Annex 56. The diagram shows the stakeholders involved in the life cycle of an IoT heat pump (blue = heat pump value chain, orange = operators and users, green = energy system). All reports are available at https://heatpumpingtechnologies.org/annex56/.

Models for IoT heat pumps
The graphic shows different types of models that are relevant for IoT heat pumps. Physical models are based on physical relationships, data-driven models are created using only data. Hybrid models are based on both data and physical relationships.

Visualisation of TCPs
After selecting a topic (in this example "Electricity transmission and distribution" was selected), this graph shows all tasks (activities) focussing on the selected topic. The topics are structured according to the IEA energy RD&D budget/expenditure statistics. Additionally, you can see the related Technology Collaboration Programmes (TCPs). Activities which had been ongoing in Summer 2020 from all IEA-TCPs are covered in this analysis. You can re-arrange the different bubbles to better meet the needs of your analysis. If a TCP consists of more than one task (activity), it also contains one entry in the database labelled “ExCo-Activities”. Available at https://nachhaltigwirtschaften.at/en/iea/visualisations/tcps-focussing-on-a-topic.php

Connections in the development of a decarbonization strategy
The graphic shows different parts and influencing factors in the development of a decarbonization strategy for an industrial company. More information can be found in the Task 3 report of the IEA HPT Annex 58 (https://heatpumpingtechnologies.org/annex58/task-3/).

Maximum supply temperature as a function of heat capacity
The graphic shows the maximum supply temperature of high-temperature heat pump technologies from different manufacturers as a function of the heat capacity. More information on the individual technologies is published on the IEA HPT Annex 58 website (https://heatpumpingtechnologies.org/annex58/task1/).

General comparison between steam generation with natural gas-fired boilers and heat pump technologies
The graphic shows conventional steam generation with natural gas-fired boilers compared to steam generation with heat pump technologies. In steam generation with natural gas-fired boilers, the steam is generated at least at the highest pressure level needed in the production process and then expanded to lower pressure levels. In comparison, when generating steam with a heat pump, it is advantageous if only the amount of steam required at the corresponding pressure level is also generated at this pressure level. Expansion to a lower temperature level should be avoided when using heat pumps. More information on steam generation with heat pumps can be found in the IEA HPT Annex 58 Task 2 report (https://heatpumpingtechnologies.org/annex58/task-2-integration-concepts/).

Different integration levels of high-temperature heat pumps and their effects
The graphic shows various levels at which the integration of a high-temperature heat pump can take place, as well as the effects. A more detailed description can be found in the Task 3 report of the IEA HPT Annex 58 and in the guideline for the development of a decarbonization strategy (https://heatpumpingtechnologies.org/annex58/task-3/).
