HRV ducting and condensate drain
Some HRV manufacturers claim that the units can be installed in a closet. But not all closets have drains for condensate.
Do all HRV or ERV units require drains? My climate only falls below 18 -20 deg C for maybe 2 days/year. I would like to put my unit in a closet, but there is no drain nearby. If a drain is absolutely required for either HRV or ERV, then i would have to relocate it.
I have noticed that some people use PVC ducting. Could aluminum flex duct that is pulled tightly also be used (the thick stuff)?
