From which it can be concluded that the most effective energy-saving measure I could make would be to put on an extra layer of clothes.
One measure not suggested in the report was the use of a dehumidifier. In damp weather it can feel uncomfortably chilly even though the outside temperature is 15 degrees or more. It is then necessary to heat the building to around 25 degrees. By removing the moisture, the environment is comfortable at a lower temperature. A dehumidifier is also an efficient substitute for a tumbler drier, extracting the latent heat from the evaporating moisture and distributing it around the house as warm, dry air.
