Supply Chain Advice Pack: Heat Pumps - pre-installation steps
Introduction
Heat in domestic properties is responsible for around one fifth of UK carbon dioxide emissions. Removing boilers and replacing them with heat pumps is one of the methods in place to help decarbonise heat in UK homes. Not only will this help reduce carbon dioxide emissions, it will also reduce other pollutants such as nitrogen oxide and sulphur dioxide which are emitted when natural gas or oil is combusted in a boiler. The purpose of a heat pump is to completely replace the function of a boiler – it will normally provide 100% of the space heating and hot water requirements.
