We (Me and my brother John) have a Danby unit (capacity-30) which we really like, so we decided to buy a second unit (capacity-30) to keep our basement and fruit cellar at a humidity reading of 45. Our basement rec room has wood paneling. The Danby unit which we already had kept the paneling in excellent shape. We are considering buying a third unit for our second story bedroom area. We have hot water heat, so we use the Danby units and ceiling fans instead of window air-conditioners. Alliant Energy likes that also!
