that's the blower motor in the old furnace. I haven't checked the new furnace, but the manual it came with says it has a 1/2 horse motor. :neutral:

Hi Bob,

Yes, true, thanks but I was already running fans. I'm looking forward to not having to do this anymore. :) (When you have 3 fans going you know you have a moisture buildup problem.)

Well it does say 1/3 HP and 6.4 amps. I may have to take back my statement:cry: It still seems high for such a small motor. However, the maker would not lie. As a matter of interest, I just looked a the name plate on another furnace motor. It is 1/4 horse, and draws 3.7 amps. So there is quite some variation.:mrgreen:

< gasp > :eek:

For sure, and newer houses are probably more airtight. On top of that if you have open topped tanks there is lots of evaporation.:wink:

yep. I remember when I first saw that I said to myself "you've gotta be f***ing kidding me". then when I found out the new furnace had the 110ac blower, I said it again..I -really- thought it had the low voltage DC motor :(

Oh well...I think the HRV only uses 38watts or something outrageously low...that I can handle. I was just really looking forward to having constant circulation throughout the house. From hearing what other people are saying, I'm really hung in suspense waiting for it to be installed. I think we're waiting on some duct work to be fabricated... :mrgreen:

Mosture................
 

Just to add to the discussion,I used to have approx. 80 or so tanks in my basement rearing angels and did not have a lot of trouble with moisture ,mainly I assume because all the tanks had glass covers ?
I had a small de-humidifier in one of the rooms which did not get overworked.
Probably the open top and vigorous turnover of water in saltwater tanks greatly assists evaporation with the results we are hearing about.
I am about to get back into marines and was thinking of open top ( I suppose this is to get as much light into the tank as possible ?) but may have second thoughts on hearing the associated problems.
Is it very difficult to keep the cover glass clean ?

You are correct, we get far more evaportaion because of our open tops and high water turn-over.

I run an open top in order to let light in, and to cool off the tank so I don't have to buy a chiller.

I evaporate about 3 gallons per day, maybe a bit more with my larger sump now.

Thanks for the info Rory. Wow ! That is a lot of moisture ..will need to consider that !
Dave.

Yep, that is why I am in the process of installing a bathroom fan hooked up to a dehumidistat!

I have a lot of water surface though, my tank is 6x2, my sump is 5x2, and my fuge is 2.5x1
