Born 1951, I grew up in Renfrewshire in a house that had been built in 1860 of granite blocks, and had not had a great deal down to it since, barring the installations of two of Shank's oldest models of water closets and hand-basins, and some unnamed maker's bath. And electricity.
Apart from the Rayburn in our dining-room (built as the kitchen originally), there were open fireplaces in every room. Only the one in the sitting-room was ever lit.
In winter we had a parafin. heater in the hall, why I do not know, as it did not manage to make any impression at all on the temperature of the hall and stair-case, a parafin convector heater in the bedroom shared by my younger sister and me, and one in Daddy's consulting-room, only during the hours of the day, when he actually was seeing patients there.
I was cold, all through my childhood, although in winter clothed in knitted woollen, scratchy vests, knitted by my grandmothers, cotton vest, cotton underpants, fleecy top pants, woollen skirt and blouse and a jumper, plus woollen knee length stockings. Later a liberty bodice of flannel was added. And long stockings (the reason for the liberty bodice as it had suspenders.)
A very small area of our beds was warmed by a hot water bottle - one to each person, and if we possibly could we smuggled a cat upstairs to act as a second hottie - one that did not turn cold during the night or develop a leak!
We washed quickly, six days a week, as the bathroom was only heated on bath nights for fifteen minutes prior to a bath being taken and while we were actually in the bathroom thereafter.
No double glazing but we did have solid wooden shutters in every room, which helped when they were closed during the winter from "lighting-up time" and until the following morning.
Considerable ingenuity was used to supply doors with draught excluders, and no child ever wore warm slippers with more glee than I.
