Deb,
Any idea how much your Dehumidifier cost? I ask cause it may have been a xmas gift :?

I might go buy one tommorow. My windows are dripping all over the place.
I guess that 3rd halide over my tank dosen't help any :roll:

I bought the one and ONLY dehumidifier at Sears Northhill. Everything was on sale, and the box had been opened. So, in the end, we got it for $235 including tax.

I think it is getting worse because the outside air is so dry this year..it is trying to suck up our tanks...... :?

Jonathan, I think you can expect to pay anywhere from $250 to $350 (for normal retail) depending on the model. I honestly can't remember -- I might have gotten mine at Canuck Tire, but I might have gotten it at Sears (Chinook Centre). I remember I got a real strange look when I bought it, but hey, if they don't want to sell them they shouldn't stock them! :)

Anyways, both places sell them. Then of course there's the usual Revy, HD, etc. etc. ....

PS. And it's not even really cold yet outside ..... :P

Well regardless of those saying a de humidifier is not needed, my windows and drywall rotted out and I had to replace them. I now have the biggest de humidifier I could get and I still have a major problem.
What was explained to me was that houses are built now so tight, that little air is incoming from outdoors where humidity is lowest. Indoors, where we heat recirculated houshould air, we increase the capacity of the air to hold much more water. As the humid warm air contacts cold surfaces, the humidity precipitates, and if enough, runs down to soak everything around.
I replace 20 to 24 litres of water nightly in my tanks. It's either get rid of a lot of tanks til the problem isn't there any more or spend more.
I've decided to spend more and buy the HRV. Here in London is a major manufacturer of Hrv's that builds for major names. I contacted engineering there and they took statistics from my house and calculated that I needed about 240 cfm's of incoming air to remedy my problem. They needed to know the volume of the house, the temperature of the house and fish room, the total surface area of the open water in the house, and how much lenth there would be in duct work there would be on both ends of the HRV.
The unit chosen is a double exchanger unit and at the top of their non-commercial types, a Lifebreath 300DCS.
