ac_hacker yeah, Italy, Venice to be exact. The problem here is summertime, with an average 60-70 % RH for 1-2 months... After nearly 15 years here did not get used to it yet!
I already checked the local electronics recyclers here, not that much unfortunately. And the thing is that you need two identical fans for an HRV in order to have a balanced system, which is not very easy to find there...
Anyway, speaking about the aforementioned fan, I can choose wether to buy a double one or two separate with identical characteristics (but, of course, doubling the power consumption, 130w each). I wonder what are the pros and cons..
Sure a system with two motors is more flexible, i.e. if I decide to swap the air inputs and outputs.
