Both stoves are connected to a small flue - a pipe within a chimney that allows smoke to escape - that leads up through the chapel roof to the outside.

Oregon State University scientists have found a way to more than double the uptake ability of a chemical structure that can be used for scrubbing carbon dioxide from factory flues.

While renewable energy sources are already reducing the need for CO2-emitting, fossil fuel-burning power plants, industrial plants that make intense use of fossil fuels are harder to make sustainable, so flue gas capture is essential.

The home’s boiler was serviced in July this year, a flue was replaced, and it passed checks, the BBC understands.
