Bvbasement
I am renovating and re-finishing my basement, which I had to demo because of mold caused by humidity and a high water table underneath our slab. After we removed the mold we brought in three residential dehumidifers which have greatly reduced the humidity in the basement, but our electricity bills have gone sky high. A waterproofer I spoke to (and trust) recommended installing the Humidex system. He said that while the cost to install is expensive (over $1000), my electric bills will go back down because it is inexpensive to run. I did some research and the Humidex just seems to be a fan that blows air out of the basement and forces air circulation in the house. Does anyone have any experience with the Humidex? Does it really work? Will it do the job of several dehumidifiers in a relatively large (1000 sq. ft.) basement?

First of all you did not indicate how you have solved the high water problem or where the humidity is coming from.

There can be multiple reasons for humidity in a basement and need different solutions.

Also you did not indicate the climate or construction detials.

Tht said as far as I can tell the humidex is basically a very expensive bathroom fan.

What is does is exhaust the relatively high humidity air for the basment. And cause it to be replaced with relatively dryer air from up stairs. That is true.

However, what they don't tell you is that in turn cause the UNCONDITIONED AIR to be drawn in from outside.

If it is hot/humid outside then that means that the AC needs to run that much more to cool and dehumidify the air.

If it cold the the furnace needs to reheat the air. That is the part that they don't discuss.

Now if the RH in the basement is high because it is relatively cool then heating the area and/or circulating warmer air from other parts of the house can help.

if the cause is excess moisture coming through the walls then aht needs to be address.

Start here.

Thanks for taking an interest in my situation. We didn't really solve the high water problem as much as we are dealing with it. We have a sump pump that keeps the water below the floor, but there is always water in the pit about 6 inches below floor level. We installed a 1/2 horsepower Zoeller pump, a 1/3 hp backup pump, and a double-marine battery backup system.

Until recently we did not realize that the clothes dryer fan was shooting air into the basement instead of through the vent to the outside. We've corrected that problem. Otherwise, I'm not sure why it's humid in our basement keeping the dehumidifiers on in the summer and spring.

I should also mention that we are putting 2 coats of DRY-LOK on our cinder block basement walls and also working on better grading our property, keeping our gutters clean, and putting in some downspout extensions so that water from the gutters is pushed away from the house.
