For many, grandparents, close or distant relatives - usually elderly people - live in homesteads or villages where private houses have never had central heating installed. In such buildings, heating is provided with the help of several furnaces and thermal walls.
Briquettes or firewood are used as fuel, which must be bought in time, sawn, split, and brought to the barn. There, the firewood must dry for one or more years, and as a result, it must be brought to the respective furnace before it is fired. All this is a very laborious process that requires a lot of strength and energy. Therefore, senior citizens pay separately for some or even each of these activities.
