My radiators are covered with items of clothing at various stages of drying. It's not that I am stingy about using the the tumble-dryer and using fuel; it is that my consciousness has been assaulted with being economic with the earth's resources. I work much like the local farmers do, observing weather patterns, waiting to quickly take and use any windows of opportunity. In my case, I wait for half decent weather so I can peg out the washing to dry in what nature can provide for the purpose. As the season changes the opportunities to dry the washing outside will contract.
I am almost wistful for bygone days when rooms in houses were large enough to sustain a wooden dryer fixed with a pulley, which rose to the ceiling. We had one, when I was young, and it settled in a high area in line with the rising heat from the coal range, mostly used for heating. Those were the days of city smog. I would not wish that back. With the thought in mind, I have been eying up any spaces that might accommodate a pulley dryer/airer. The obvious one would be our utility area, but that is far too narrow.
Damp is another issue to think about. These days, with smaller room sizes and the encouragement to insulate houses well, ventilation is more restricted. On the other hand if a house is heated with dry heat, a little moisture might balance things off a bit. The correct balances could be difficult to achieve.
Increasing heating costs focus the mind and the purse. Where I live, there are very limited periods when the heating is completely off during the year. The thinking cap will have to go on again. Meantime, the airers over the radiators and the radiators themselves will have to do their best to support the ecological argument on the basis that every little helps it, and also, every little helps to support the domestic economy drive.
