Exterior duct material? ERV port is covered in snow
I am finally moving into my pretty good house in NH. I installed our ERV system during the summer of last year. Being new to metal roofs, I underestimated how much snow would pile up.
Needless to say, our ERV exhaust/supply port (panasonic) becomes buried after each storm.
I am thinking of removing the existing dual-function exhaust/supply port and using two separate ducts that will be oriented upward and outward like two opposing snorkels.
Will galvenized duct work for this? The base will almost certainly be covered in snow all winter… Are there better materials for outdoor use? I want to avoid PVC.
Any other ideas?
