Re: Exracting 20 liters/24hr water in dehumidifier in oNew H 8May 25, 2016 1:04 pm Stewie D What is the floor - concrete slab on ground or raised timber bearers and joists ? What about soil drainage around the perimeter of the house ? Wood subfloor over wood floor joists. House is built on a poured concrete perimeter foundation and 4ft crawl space, which is soil with a 6 mil vapor barrier over it. Soil drainage is good (sandy loam) with the ground water at least 8ft below the surface. The moisture in the air has to be coming from somewhere but given that you are experiencing such high humidity it may be just that the dehumidifier is extracting all that water from the air that has made its way inside your house. It is not unusual in places like Northern Australia ( or any other place with relatively high humidity ) for dehumidifiers to remove large amounts of water from moisture soaked air. The floor is extremely tight (as is the whole house). Opening or closing an exterior door causes one's ears to "pop," so I suspect infiltration is very low overall. The floor is insulated with R30 fiberglass bats, but no vapor barrier in the floor. The floor covering is about 50% vinyl and 50% carpet over rubber pad, neither of which is very permeable. It's possible the moisture is coming through the floor (I can't think where else if might be coming from), but we lived in this climate before w/ a crawl spape (and no floor insulation), no dehumidifier and never noticed humid air in the house. I am just amazed that 5gal per day is almost 2000 gallons per year, or enough to fill a 55 gallon drum every 10 days or so, which equates to darn near a quart per hour, which would be a pretty decent flow, or leak if it were dripping from a leaky pipe, yet this moisture is in the air. I have no reference to know what a LOT of water from the air actually IS, so maybe it's normal; maybe it's not. I'd love to know what "normal" is, I guess.
