someone has to fail, so the rest of you look good
Good morning HBT
I was hoping one of you fine geniuses might be able to help me this morning.
I finally did my first brew in my new Basement Brewery, this weekend.
I know you are shocked to hear I brew in the basement
I have an Electric Kettle 10 gallon Kettle making 7 gal batches. ( another shock Electric !!)
Blichmann Boil Coil 10 gal 240 V = 3750 watts at 100% power
I am about 65% for a rolling boil = 2437 watts - I am only boiling 7 gallons
And I have a 4 inch 190 CFM vent fan pulling off Steam all the steam went up into the vent fan.
I have a 30 QT SS mixing bowl as a vent hood got the idea from this thread
https://www.homebrewtalk.com/showthread.php?t=418665&page=2
And the hood is only 12 inches above the kettle.
I am getting a HUGE amount of water dripping back threw the Vent Fan !!!

By my calculations, if the Boil Coils is running at 100% for boil I would need a 225 CFM vent fan
But I am not running at 100% for the boil only about 65% = 143 CFM and the fan is rated at 190CFM
There are several people in the Easy &Cheap Vent Hood thread doing 12 gallon boils 10 gal batches
With the same 190 CFM fan, and not having the same problem I am ..
I have a run of about 2.5 ft. of the Flexible Dryer type 4 inch Hose up to a 45 degree turn to a Straight 4 inch pipe out of the house.
Total run is probably 5 ft.
I managed to wrap a towel around the fan to soak up all the water dripping.
And the fan managed to survive all the water, but it shouldnt be dripping!?
I have a video of how bad the water in the fan is. I am attached a Movie - you can see for yourself how much water.
Do you see the water running around the edge ? Crazy !!!
SO the question is am I not calculating the CFM needed correct?
I only have a 4 inch pipe out of the house same kind of exterior hook up as the Dryer Flapper vent you see everywhere.
Should I Switch to a 6 inch fan and reduce at the exit point back to 4 inches? ( Back flow problem ? )
http://www.amazon.com/dp/B005XNNYMU/?tag=skimlinks_replacement-20
Basically going from 190 CFM to 460 CFM almost 2.5 times the power !
Or add a helper in line fan to boost my total CFM ? And I stay with 4 inch no reducer from 6 to 4 ?

Adding 65 cfm to 190 cfm = 255 cfm total = not a huge help I agree . But a cheaper option.
Or could it be the temperature doing all the condensing thus resulting in the rain in my fan ?
It was 60 F in my basement brewery
It was 25F outside
How is everyone else getting all that steam outta your basement brewery ?
Thanks in advance for all your help!!
What would I do without the HBT ?
