Oddball (Post # 6)makes an excellant case for not doing it-at least without some pretty sophisticated ion filtration to remove metal complexes. Too bad, I get about 20 litres a day from mine and thats in the winter.
Imagine what it would be in the heat of summer!
Wow!! I didn't realize that dehumidifier water is bad for the fish tank. I've been dumping all my dehumidifier water into my fish tank for 2 months now. 
Actually I've been doing this for the last 2 years 
. I guess I better stop doing that for now until I have investigated further

"A dehumidifier works by simply condensing water from the air (from the water vapor that is present in household air) and collecting it. Since this does not involve boiling the water, the water is not sterilized. In fact, older dehumidifiers, which may not have been cleaned out, can feature many fungal spores in the equipment and in the water that is collected (since fungal spores are naturally found in damp air anyway). So, while the water collected in the dehumidifier may not contain problematic minerals and chemicals, such as sodium or chlorine, that might be in your town water supply, it can contain high levels of microbial contamination and it not suitable for drinking or for hydroponic systems--unless it is boiled first."
That said, a well kept and clean one may be a good option if you are looking for water without the chemicals and minerals. I would definitely clean the unit and sterilize it often.
