Quote taken out of context:

There are gas appliances, cookers and room heaters,
also gas clothes dryers, which can vent damp exhaust
directly to the room. But even when I paid for water,
I never fretted about the cost of humidity.

I'd like to be able to switch my clothes dryer to venting into the
room to conserve heat. It needs to be switchable when the weather is
warm, but I doubt that a dryer would put more water into the house
than clothing dried on racks, and they always dry fast enough to show
that they haven't raised the humidity much.
