Running it overnight once a week in this fashion gives good results. Running it more often yeilds less water for every extr kW of power used.This will vary however depending on use of showers, dryers, number of occupants, method of heating (ie gas introduces loads of moisture), local geography, etc. sounds right. try to run it just before temps go down and the windows turn into a dehumidifier! also run it over night and get 10x of what i get during the day. its good to get things really really dry every so often as it lets the carpets/furniture actually dry out for a change.	tweak'e (69)

Nope, not really. thats why some of the better dehumidifiers have built in heaters But all within reason of course , as they work by cooling air to remove the moisture, so if the room is really hot it might struggle Colder air can hold less moisture than warm air (thats how they work), so by definition cold conditions = less dampness in the air.	1101 (13337)

The two main bedrooms at opposite ends of my house had major problems with condensation and mold, the entire end walls would get damp to the touch on a cold morning and even the ceiling would get damp at times. My solution is a very expensive one though, I had double glazing installed in the whole house (about $3500), put an extractor fan in the bathroom & laundry and a rangehood in the kitchen (~ $600 all up), put a wall heater into my bedroom ($30), and had my entire house cladding repaired and repainted (~$15k but may not be part of what actually helped just had to happen). I also changed my habits by opening windows regularly (or at least using the 2nd latch) during winter instead of sealing the place up tight and trapping moisture in. Now I get very little condensation at all and only on the bottom 20-50mm of the window glass on very cold mornings. I non longer get damp walls or ceilings at all and no more mold. Another thing I did was give away my gas heater and have A/C installed but that was before the bulk of it and only helped a little. Reducing moisture is not really a trick, remove it at the source (Bathroom, Kitchen, etc), keep the house ventilated, have good insulation & heating. We breathe out a lot of moisture and it accumulates particularly in our bedrooms overnight, opening a window for a while every day can make a huge difference. Dehumidifiers can be great tools but it's really treating the symptom and not the cause so should be a last resort when prevention isn't possible.	dugimodo (138)

Dehumidifiers can be great tools but it's really treating the symptom and not the cause so should be a last resort when prevention isn't possible. absolutely. things like unflued gas heaters and cookers really pump out the water. however ventilation and insulation tend to be opposites. the more wet air you blow out the more cold air comes in to replace it. wood fires are really bad for it. still its a good trade off if you have decent insulation and a source of cheap heat.	tweak'e (69)
