| Hi -- I need some advice about what size dehumidifier I need for my unheated basement in MA. My house was built about 1870 and has a rubblestone foundation. About half of the basement floor has a thin veneer of concrete and the rest is dirt. Up to now, I didn't attempt to run a dehumidifier because it seemed like it would just be a losing battle, but after flooding last spring (like most of eastern MA and RI) and a humid summer, the humidity level down there has not returned to normal.
The basement footprint is 1000 sq. ft. and the ceiling height is just under 8', if that helps. I plan to run a hose from the dehumidifier to my sump so I won't have to empty the dehumidifier tank manually. Also, if anyone can recommend a particular brand or model that is quiet, reliable, energy-efficient, and designed to run at lower temperatures, I would appreciate it. Thanks! |

| You need a dehumidifier with at least 9 liters a day capacity. Sealing the soil-only portion of the floor will also do a great lot to reduce water vapout in the basement. |

| Thanks, Worthy. So that would be about 20 pints, right? What's the best way to seal the dirt floor -- putting down plastic sheets? |

| 19.03 US pints. But you should always round up when it comes to dehumidifiers. 6 mil poly should help, as long as you don't walk on it. Better yet, 4 inches of concrete atop 5 inches of gravel. |

| Thanks. I'll try the plastic. I'd love to put down a proper concrete floor, but it will have to wait. |
