Question DetailsAsked on 8/20/2013

I'm looking to install a dehumidifier/ventilation system in my basement but not sure what kind. Humidex? Wave?

This is a 1k sf basement on the coast on Cape Cod. I want to install something that doesn't need emptying.

Do you have the same question? Follow this Question

If you want a basement system that just vents basement air to remove accumulated air and odors, a Wave and Humidex system will do that - so will a simple in-wall fan with humidity activated switch costing much less. The Wave and Humidex systems do not remove the humidity from the air - they just vent the humid air outside. This results in neative pressure in the area they are installed in so air is sucked in from the rest of the house to make up the difference, and outside sucked into the house to make up that. Therefore, you are venting 100% heated or air conditioned air to get rid of the humidity, which is terribly energy inefficient. It is far more efficient to remove the excess humidity with a dehumidifier and provide needed air circulation by another means, such as a fan in the basement, or by having the HVAC system pull a greater portion of its internal recirculated air from that area if it is enclosed, or pull makeup air from there if it is outside the building HVAC envelope (a rare thing).

A properly designed HVAC system taking and putting conditioned and/or heated air where it should be is waht you want to use, and individual zone controls to do this are likely to pay for themselves in about 10 years of use, or in many cases much less.

your concern about emptying a dehumidifier tray can be eliminated in most cases by plumbing a dehumidifier to a wash tub, sink, or floor drain.

Try The Breeze, sold by Breeze Systems International. They sell on Ebay and Amazon for about $299 and do an amazing job exhausting humid air from your basement. They are not just a fan and only a fan will not have the same results. You will be able to use your basement without getting sick from all of the toxic and foul smelling air. And, it costs as much as two nigh lights (9 watts) to run.
