Hi Eric, thanks for the reply mate.
So far, im not having any problems with dew on the secondary, but the primary seems to dew up pretty quick some nights, hence the thoughts of a dew heater.
So as long as i can somehow get the air moving across the surface of the primary, there would be no need for me to buy a heater??
That article seems like a good idea (and a lot cheaper than dew heater gear..lol), i might give it a try
thanks mate
