I’m installing a standalone ERV system in an unconditioned attic and want to utilize the Zhender comfotubes for ease of installation and commissioning the system to ensure each room is receiving the appropriate air flow, but Zhender recommends the tube be installed in a conditioned space.
Would there be any issue with running the comfotube thru an r8 4″ inch flexible duct?
I live in climate zone 3 in the USA and freezing is not an issue.
My thought is that the insulation would help with heat transfer.
Any input is appreciated
