Is there a ventless / heat pump option for bathroom exhaust?
I am designing / building my first passive house. I am located in Nova Scotia, currently working out the details for my HRV/ERV system, and evidently confronted with the issue of bathroom exhaust fans.
I have been offered the same advice as most; from controlling the humidity peaks with the HRV/ERV system to traditional venting directly outside.
I am not keen on the idea of relying on my HRV/ERV to handle bathroom humidity (not to say it cannot work if designed correctly), and I am not interested in compromising my air barrier with the traditional approach.
Does anyone have any experience with a whole-house bathroom humidity control system with a heat pump? A closed-system, entirely inside the building envelope, and independent from the HRV/ERV? Perhaps similar to the concept of a heat pump dryer.
I am unsure as to how this would affect the HRV/ERV system-balance when active, and also if there would be any issues with the local building code.
I am open to any ideas or feedback.
