No full textAbstract copyright UK Data Service and data collection copyright owner.
The Domestic Heating Data from the Energy Systems Catapult Living Lab, 2017-2018 was collected to help the energy industry better understand how people use their heating systems; allowing them to design low carbon products and services that meet the needs of consumers. A range of home heating data was collected by the Home Energy Services Gateway (HESG) from approximately 100 domestic properties in the United Kingdom. Further information about these data can be found on the Smart Systems and Heat Website and on the Energy Systems Catapult Website.Main Topics:This study includes data collected directly from sensors in each room, such as room temperature, room humidity, gas usage, electricity usage, radiator temperatures, boiler temperatures and water temperatures (hot and cold). In addition, data on how participants use their heating system was collected, including the times they request heating, the target temperatures requests and the type of schedule changes made. Finally, it covers local weather data, including forecasts and local observations

Investigating the effect of the throwing arm length on the horizontal distance travelled by an object that is thrown from a catapult
Get PDFThis essay investigates the effect of the throwing arm length on the horizontal distance travelled by an object that is thrown from a catapult. This investigation attempts to answer the following question: “How does the length of the throwing arm affect the horizontal distance travelled by an object that is thrown from a catapult?”. To answer this research question, an experiment was designed and performed. A wooden catapult and five wooden throwing arms with different lengths were constructed. The same object was thrown for five times with each throwing arm and the horizontal distance taken by the object with each throw was measured. The mean horizontal distance the object had travelled was greater when thrown with the longer arms, and the differences between the means were significant (p<0.001). This study provides a better understanding of catapults and the principles that it works with
Training for design of experiments using a catapult
No full textDesign of experiments (DOE) is a powerful approach for discovering a set of process (or design) variables which are most important to the process and then determine at what levels these variables must be kept to optimize the response (or quality characteristic) of interest. This paper presents two catapult experiments which can be easily taught to engineers and managers in organizations to train for design of experiments. The results of this experiment have been taken from a real live catapult experiment performed by a group of engineers in a company during the training program on DOE. The first experiment was conducted to separate out the key factors (or variables) from the trivial and the second experiment was carried out using the key factors to understand the nature of interactions among the key factors. The results of the experiment were analysed using simple but powerful graphical tools for rapid and easier understanding of the results to engineers with limited statistical competency
Electrification of Heat Demonstration Project: Heat Pump Performance Cleansed Data, 2020-2023
No full textAbstract copyright UK Data Service and data collection copyright owner. The heat pump monitoring datasets are a key output of the Electrification of Heat Demonstration (EoH) project, a government-funded heat pump trial assessing the feasibility of heat pumps across the UK’s diverse housing stock. These datasets are provided in both cleansed and raw form and allow analysis of the initial performance of the heat pumps installed in the trial. From the datasets, insights such as heat pump seasonal performance factor (a measure of the heat pump's efficiency), heat pump performance during the coldest day of the year, and half-hourly performance to inform peak demand can be gleaned.
For the second edition (December 2024), the data were updated to include cleaned performance data collected between November 2020 and September 2023. The only documentation currently available with the study is the Excel data dictionary. Reports and other contextual information can be found on the Energy Systems Catapult website.
The EoH project was funded by the Department of Business, Energy and Industrial Strategy. From 2023, it is covered by the new Department for Energy Security and Net Zero.
Data availability
This study comprises the open-access cleansed data from the EoH project and a summary dataset, available in four zipped files (see the 'Access Data' tab). Users must download all four zip files to obtain the full set of cleansed data and accompanying documentation.
When unzipped, the full cleansed data comprises 742 CSV files. Most of the individual CSV files are too large to open in Excel. Users should ensure they have sufficient computing facilities to analyse the data.
The UKDS also holds an accompanying study, SN 9049 Electrification of Heat Demonstration Project: Heat Pump Performance Raw Data, 2020-2023, which is available only to registered UKDS users. This contains the raw data from the EoH project. Since the data are very large, only the summary dataset is available to download; an order must be placed for FTP delivery of the remaining raw data. Other studies in the set include SN 9209, which comprises 30-minute interval heat pump performance data, and SN 9210, which includes daily heat pump performance data.
The Python code used to cleanse the raw data and then perform the analysis is accessible via the
