PassivHaus Clothes Dryers?
I would like to learn more about how those building to the PassivHaus airtightness guidelines deal with the clothes dryer.
I did some internet research, but couldn’t find much information on the CFM rating for clothes dryers. I’m assuming they are rated at 200 – 400 CFM, depending on the size the of the dryer. With the current trend toward bigger appliances, perhaps it’s even larger than that . . . I don’t know.
For a house built to 0.5 ACH50Pa, does this throw the system off balance? Do clothes dry? Is there enough air exchange?
I know that you can purchase make-up air kits (ducted valves) for the larger range hoods, and code that requires them above a certain CFM rating . . . but this doesn’t seem like a sensible solution. Maybe we need fresh air intakes for clothes dryers (like they have on woodstoves!).
What about condensing ventless dryers? I found a couple models online that are mfg. by LG. They are available in the US. Reviews are mixed. Anyone have any experience with these?
I guess I won’t even ask about heat pump dryers 😉
