The Electrification of Heat (EoH) demonstration project is funded by the Department for Business, Energy and Industrial Strategy* and seeks to better understand the feasibility of a large-scale roll-out of heat pumps in homes across the UK. It aims to demonstrate that heat pumps can be installed in a wide variety of homes and deliver high customer satisfaction across a range of customer groups. This dataset is derived from the monitored heat pump performance data and provides a summary of the performance data quantity and quality and the data analysis outcomes. Each column of data in this dataset is described within the data dictionary included in the "Additional Documentation". It also contains a unique property ID number which can be used to link this data to all other published project datasets. The heat pump performance data was collected at an average of 2-minute time intervals. It was then stored in it's raw form. To prepare the data for analysis, data cleansing was undertaken and a cleansed dataset was produced. The cleansed data was then quality checked and analysed and the outputs of this process form this dataset. Two written reports which are included in the "Additional Documentation" outline the process in more detail and insights derived from this data. *as of February 2023 Department for Energy Security and Net-Zero (DESNZ)
