Re: [Killietalk] air exchanger

["David Lains" <david at zfin_org>]

Hello All

All three fishrooms in my neighborhood have them installed.  I bought mine
off ebay for about $350, they are hard to find on ebay though.

Just a quick search found this one for $500

And this one for $459 or $350 for bidding
http://www.smarthome.com/3033.html

They save your house, make your room nice and fresh (both a great feature if
you have a significant other) and if you heat your air dryer air warms up
quicker.

Here is a great image of a basic install.

If you live in a cold climate make sure you get  an HRV (heat recovery
ventilator) not a ERV (energy recovery ventilator).  The later allows
moisture across the heat exchange surface for use in dry climates where you
are using the unit to keep cold in and heat out.  We want to keep cold out
and heat in and leave the moisture out.
Google: air to air heat exchanger hrv

I wouldn't imagine having a fishroom without one.   

Thanks Barry for showing me the way!

Best fishes

Basically an air exchanger takes air from the outside and exchanges it for
air from the inside, keeping the humidity down. The important thing, though,
is that it passes the air over an air-to-air heat exchanger, which prevents
you from losing a lot of heat from your fishroom. That is the difference
between an air exchanger and a simple extraction fan. You can set them to
keep the humidity at a chosen level.

They are a significant investment - about 50 bags of Notho eggs at 
$20/bag. ;-)   I don't expect I'll recoup that any time soon.

I think they are a good investment though, in preventing damage caused by
dampness as well as growth of mold. When I built my fish house, I did not
install one right away. The first winter water was running freely down the
glass of the doors and mold started to grow alarmingly soon. I had the air
exchanger installed and it immediately stopped the problem.

Consult with a local air conditioning firm about costs. They may be able to
get you a deal, but it won't be just spare change.
