Dehumidifier sizing

Posted by k on September 29, 2005, 9:47 pm

I need to size a dehumidifier for a basement that's about 1,050 sq ft. The
space is irregular but open, and there is a floor drain available. I don't
know how to specify one, and am probably asking the wrong questions on
google. Is there a chart somewhere that will help me size a unit.

This is a damp basement, and for the first time it's smelling moldy (or
maybe just crappy). We rarely go down there, so is a dehumidifier even our
best bet?

thanks,
Keith

It is really hard to say. It depends on how much moisture is coming in.
That is difficult to measure.

There must be guidelines somewhere, that's what I'm looking for. Moisture
is cumulative, no? I'd like to get rid of what's there (along with the
smell of it), and contain it in the future.

thanks,

Nope. It depends of how the water is getting in, and how much of it
there is. So the depth of the water table, how leaky the walls
doors, and windows are, and whether there's water against the
foundations, the presence or absence of open sumps, and whether
the blowoff valve on your water heater is venting all affect the
question more than how big the space is.
