Heating homes, businesses and industry accounts for nearly half of the energy used in the UK, and a third of its carbon emissions. As businesses look to save energy and move away from fossil fuels in the fight against climate change, an efficient means of providing this heat is essential.

Heat pumps overview guide

Published December 2018

Due to increased use of renewables, and reduced use of coal, the official carbon intensity of grid electricity in Great Britain decreased by approximately 15% from 2016 to 2017. Using electricity as a source of energy for heat has therefore also become less carbon intensive, and based on current grid projections this trend is set to continue. It is therefore essential that businesses have a good understanding of heat pump types, applications, finances and ongoing operational requirements.

This 18 page guide provides an overview of heat pumps to help businesses know when to consider using this technology, and to ensure systems are properly implemented and run as efficiently as possible. It is aimed at businesses in all sectors, as electrically powered heat sources are becoming much more common for providing heat than gas-fired sources.
