ERV Installation and Duct Design
Appreciate your input and thanks for this awesome resource of a site.
I’m planning to part-DIY install an ERV in our house, and would like help to make sure I get the duct pathing and sizing ‘roughly’ appropriate. Please see attached picture.
Thoughts? Are there any optimizations I should be thinking about in terms of locations of Y-splits etc.. For the two rooms on the right, I’m thinking I should split them a little earlier than shown, to avoid unwanted sound travel between rooms?
Second but related question. I saw an article or maybe a forum reply on here a few days ago somebody commenting that it’s not worth installing AC supply vents in small bathrooms. Well, we have the AC registers in the master en suite and family bathroom which are fully closed year round (except for leaking air that makes it through the closed grilles). We have never used them and there’s probably more loss/leakage from them than useful cool/heated air.
Thanks again for any input! Hopefully the diagram helps and my overthinking will be interpreted as ‘good planning’.
edit: Added another diagram with slightly different routing, repurposed AC vents in the bathrooms, and proposed duct sizes.
