It's double glazed with thermal curtains, including over the door (which is new and no discernible drafts). It has a radiator at each end and a woodturner in one end with an open fireplace (chimney blocked and insulated as the aerial wires come down it). It is next to the utility which has a thermal curtain over the door on each side!
The house is 18/19 century brick and flint with loft insulation in every part of the roof we can access.
Even if the fire is in overnight, the room is the coldest in the house! What can I do to make it more pleasant?
I have my eye on a heated blanket but making do with double tog weimaraners at present.
