Abstract: To limit global warming, a rapid reduction in the carbon emissions from our buildings is required. Heating buildings contributed to 17 per cent of the UK overall carbon emissions in 2018 which is why it is important we look to decarbonise the heating systems that serve our buildings. In 2020, only 7.9 per cent of the energy to heat our buildings came from renewable sources. In the UK, existing heating is predominantly by natural gas. The most significant challenge is the rural buildings that are not served by mains gas but have oil supplies, due to the high carbon content of this fuel. The Diocese of Gloucester was invited to participate in a research project carried out by Historic England into viable methods of low and zero carbon heating in churches and their associated buildings. The focus of this research explores oil-fired heating systems as this fuel produces more carbon dioxide emissions than other fuels used to heat buildings. The key finding from this research is that no single heating technology is recommended for either all historic buildings or even each historic building type. Across the six case studies, air source heat pumps, biomass and electric heating were recommended in an equal proportion of cases. It is not possible to determine the most viable heating technology without carrying out a detailed technical feasibility study at the early concept stage of a project. The recommended heating technology depends on many factors including the building’s site and location, the size and form of the buildings, the use and operation of the buildings, the condition of the existing heating system and the existing utility infrastructure. The wider background to this research includes the 2030 net zero carbon target set by the Church of England and the UK government’s 2050 net zero carbon target.
