Along with others, yes, we had just the one coal fire in the ‘kitchen’, which was actually the living room. There were fireplaces in the two bedrooms and the front room. The latter was lit at Christmas and that was it. We maybe had our bedroom fire lit if we were ill in bed, the mumps outbreak comes to mind.
Later on, we had an electric wall heater in the bathroom, probably switched on just before our weekly bath, and switched off pretty quickly.
We wore vests, wool jumpers and socks, had hot water bottles in our bed at night. The winters must have been long and cold, but somehow we managed.
