skaffen Posted May 7, 2008 Report Share Posted May 7, 2008 Hiya I left the hood on my 440 L tank partially open last night, and there was lots of condensation on the lounge windows this morning (man it was cold last night). How do people with open tanks get on, do your get increased condensation in your homes in winter? -Si Quote Link to comment Share on other sites More sharing options...

Simian Posted May 7, 2008 Report Share Posted May 7, 2008 Oh yeah. Thats why a nice tight lid is a wonderful thing. My 5' drops markedly over the week between water changes, I would guess I lose 10l a week from it, it has to go somewhere. Quote Link to comment Share on other sites More sharing options...

Faran Posted May 7, 2008 Report Share Posted May 7, 2008 One of the main reasons why we got an HRV system in the house, actually. Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 7, 2008 Report Share Posted May 7, 2008 and does the system work well? Quote Link to comment Share on other sites More sharing options...
suphew Posted May 7, 2008 Report Share Posted May 7, 2008 My tank loses about 60l per week. I have a semi sealed canopy and an extractor fan that pumps the damp air outside. Quote Link to comment Share on other sites More sharing options...
supasi Posted May 7, 2008 Report Share Posted May 7, 2008 I have that problem as my planted tanks are open topped. Condensation is a big problem I have a DVS system. Basiclly it is useless and all it does is create cold draughts. I put a dehumidifier in the room at night on cold night and wipe and open windows in the morning I believe that so long as i own fish, i will have to live with condensation.

skaffen Posted May 7, 2008 Author Report Share Posted May 7, 2008 Yeah, I've heard mixed reports on DVS systems. I think it's dependent on your aspect, roof pitch and volume, etc. It's gonna be cold again tonight so it'll be interesting to see how it goes with the hood closed...

skaffen Posted May 7, 2008 Author Report Share Posted May 7, 2008 Open the windows in the morning Yeah, that lets the moisture out. Unfortunately it lets the scumbags in when I'm at work... Quote Link to comment Share on other sites More sharing options...
David R Posted May 7, 2008 Report Share Posted May 7, 2008 Other than keeping the tank well covered there's not much you can do about it. I've used dehumidifiers before and found they just chew thru the power and make the tank evaporate faster. Quote Link to comment Share on other sites More sharing options...
HaNs Posted May 7, 2008 Report Share Posted May 7, 2008 Try a HRV type system. Had bad cond before tanks. Now we have no cond with the HRV I swear by the HRV type systems now! Quote Link to comment Share on other sites More sharing options...
Simian Posted May 7, 2008 Report Share Posted May 7, 2008 The ventilation systems with heaters will use more power but ultimately will be more effective. As the principle is that it moves the warm dry air from your ceiling into the rrom to force out the moist air, it will only be of use in the evening in winter if you havea heater attached. if your system does not have one it will turn off once your ceiling temp drops below 7-10 deg, which it will at night in winter.

I've never found my roof space to be more than a few degrees warmer than it is outside(During the winter). Yay, let's blow cold musty air from the roof into the house. Now, different case during the summer. But then why would you want to blow 50° musty air into your house? Quote Link to comment Share on other sites More sharing options...
HaNs Posted May 7, 2008 Report Share Posted May 7, 2008 Ours works well all year round. BEST IN WINTER. No heater built into the HRV It only was only musty when was first installed. You can take cool air from outside in summer. Quote Link to comment Share on other sites More sharing options...
jim r Posted May 7, 2008 Report Share Posted May 7, 2008 Our HRV system is brilliant, just ask my wife. No probs since we got it. Cost about $ 3800 with 7 outlets. Quote Link to comment Share on other sites More sharing options...
skaffen Posted May 7, 2008 Author Report Share Posted May 7, 2008 Is that the actual HRV brand? Been thinking about getting one the last few winters... Quote Link to comment Share on other sites More sharing options...

Barrie Posted May 7, 2008 Report Share Posted May 7, 2008 when the outside temp is say 26 degs, how cool is it inside? At my place in summer its a nice cool 18 My house is quite small and single leveled and I only need one outlet but the cost of my heatpump/air con was also $3800 with our weekly power use the same (in winter) as a bottle of gas for the gas heater If I was to move homes, I would put an air con unit in before I moved in Warm in winter and cool in summer Quote Link to comment Share on other sites More sharing options...
David R Posted May 7, 2008 Report Share Posted May 7, 2008 Yay, let's blow cold musty air from the roof into the house. If you're blowing the musty air out then its not going to stay musty very long is it... Quote Link to comment Share on other sites More sharing options...
henward Posted May 7, 2008 Report Share Posted May 7, 2008 DVS system + thousands a nice tight nig fittin lid, you can even silicone the ends to almost air tighten it, would ecrease this by 90% also, its beter for fish cos if water goes, all the nasty stuff stays.... concentration increases, thogh its marginal. i have mine in the garage, so it doesnt matter if its humid Quote Link to comment Share on other sites More sharing options...

David R Posted May 7, 2008 Report Share Posted May 7, 2008 i have mine in the garage, so it doesnt matter if its humid Until the rafters start rotting.... Probably not likely to get that bad unless you've got an indoor pond tho. Quote Link to comment Share on other sites More sharing options...
matthewY Posted May 8, 2008 Report Share Posted May 8, 2008 Condensation? I like my condenstion, it makes me fell like i own fish tanks ;-) Anyway, I think the tight seal is right, I only started noticing that around the "opened" area where the pipes are going in/out, theres some moisture issues around the hood. I plan to seal around the pipes and see how that goes. Also lookign at putting insulation around the tank wall (ontop of teh pretty backing i have) and also on a large part of the lid where alot of teh heat would escape from (good use of power even if it might not have effect of reducing moisture).
