Fan-vent thoughts

just another angle to consider, strip the moisture from the air instead of exhausting the air.

Thats why i thought i would clarify the "room" more of a large closet space and will be lots of space under tank. I dont think a dehumidifier can handle the volume?

I was actually looking at getting one myself and for $200 you can get a portable dehumidifier that is rated for a 2000+ sf home: http://www.sears.ca/catalog/dehumidifiers/12996

I think that rating is based on a regular humid house, not one with a 425g tank? I have read that dehumidifiers have not worked for people with large systems due to the amount of evaporation?

Just came across the following;

I can have access to two other vents coming from a gas fireplace, I imagine one is an intake and the other is out?

This has been mentioned earlier, but...
If you have a bathroom fan on 24/7 you are exiting warm air, and cold air is coming in from outside to replace that air. You have to heat all that cold air. Not very cost effective method.
Even if you put in a vent in the closet that replaces that exhausted air, your chimney from your boiler might flow backward and you could get carbon monoxide poisoning. You should talk to a heating specialist.
You want to have + pressure in a house, not negative.

Once you get the pressures figured out, there are humidity control units that will only start the fan at a preset humidity level.

+100.
Just to clarify, you do not, under any circumstances, want to attach anything to your boiler boiler venting.
If you add up all the things in your house that exhaust air, you have to make sure that air is being replaced. If it's not and your house runs at a negative pressure, it will pull flue gasses back down your boiler venting. It's the easiest path for the air to come from.

You really should have a pro come over and see what you're faced with and what you have in the house already to make an informed proposal that you can make decisions with. With any gas fired appliances in the home, the dangers of not balancing out the system are too dangerous and should not be attempted without that on site visit from someone who fully understands those venting requirements.

+1 to the HRV, initial install costs may be a bit higher but you will save a lot more long term

I agree. Is a heating/plumbing pro the best person to come over and advise me on this or another profession?

Thanks all.

Just took mine out of comission, doesn't cut it in cold weather with large tanks.

I drilled two holes through the wall, one is a 4" that connects to the fan above everything, the secons is a 2" that i plumbed down the wall to enter at floor level. My room is fairly sealed so its not like I'm heating and cooling the whole house, It just takes care of that room.
