@Siksuker, European and Japanese electric dryers have heat exchangers built on to the back. They are way ahead of us. I saw one when visiting folks in Austria.


@Denny, The contractor that rebuilt the crawlspace had two commercial dehumidifiers running for several days in the crawlspace after work was finish. I was amaze at the amount of moisture they captured. My electric bill was the highest bill I ever paid!
Even if you have a fan drawing air out of the basement the air that it draws out has to be replaced by air somewhere. I think it is irrelevant.
