Industrial Heat Pumps, Second Phase

The official end date of Annex 48 is 31/03/2019. Compilation of the final report is ongoing.


Industrial heat pumps (IHP) are active heat-recovery devices that increase the temperature of waste heat in an industrial process to a higher temperature to be used in the same process or another adjacent process or heat demand. While the residential market may be satisfied with standardised products and installations, most industrial heat pump applications need to be adapted to unique conditions. In addition a high level of expertise is crucial.

This Annex is a follow-up-annex from the previous completed Annex 35 “Application of Industrial Heat Pumps”. Industrial heat pumps within this Annex are defined as heat pumps in the medium and high power range and temperatures up to 150 °C, which can be used for heat recovery and heat upgrading in industrial processes, but also for heating, cooling and air-conditioning in commercial and industrial buildings.


The main goal of this Annex is to overcome still existing difficulties and barriers for the larger scale market introduction of industrial heat pumps. The results should be concentrated on the development and distribution of condensed and clear information material for policy makers, associations and industries. Focus will be concentrated on a limited number of process industries with large potential.

The objectives will be achieved by common studies performed by the participants for each country. The main focus of the Annex will be on arranging the information on heat pumping technologies for industry to designers, decision- and policymakers in such a way that it will lead to a better understanding of the opportunities and to use these in the right way in order to reduce the use of primary energy consumption and the CO2-emisions as well the economy of industrial processes.
