Abstract
With electric heat pumps substituting for fossil-fueled alternatives, the temporal variability of their power consumption becomes increasingly important to the electricity system. To easily include this variability in energy system analyses, this paper introduces the “When2Heat” dataset comprising synthetic national time series of both the heat demand and the coefficient of performance (COP) of heat pumps. It covers 16 European countries, includes the years 2008 to 2018, and features an hourly resolution. Demand profiles for space and water heating are computed by combining gas standard load profiles with spatial temperature and wind speed reanalysis data as well as population geodata. COP time series for different heat sources – air, ground, and groundwater – and different heat sinks – floor heating, radiators, and water heating – are calculated based on COP and heating curves using reanalysis temperature data. The dataset, as well as the scripts and input parameters, are publicly available under an open source license on the Open Power System Data platform.

This paper introduces the When2Heat[5] dataset comprising the first ready-to-use national time series of both the heat demand and the coefficient of performance (COP) of building heat pumps
The data that serve as an input to the calculation of both the heat demand and the COP time series are introduced
Summary
In view of the global energy transition, open energy data are more important than ever[1]. The COP of the heat pumps, which is defined as the varying ratio of their heat generation and electricity consumption, changes over time This variability will be essential for the future electricity system balance and needs to be considered in related system and market analyses[3,4]. Against this background, this paper introduces the When2Heat[5] dataset comprising the first ready-to-use national time series of both the heat demand and the COP of building heat pumps.
