Ventilation for Shipping Container House
Hello, I have been reading up on heat exchangers and wanted to ask some questions. I am building a 20’ container tiny house with a walk in shower. I have 2” closed cell foam board on the interior with 2.5 inches of closed cell on top of that in between the studs. My winter lows are around 0 degrees Fahrenheit. The container is fairly air tight so I am trying to figure out the best way to vent the bathroom and container together in order to reduce humidity levels and indoor contaminates. What would be the most efficient system for this small but sealed space? A quality ceiling vent or an air exchanger? Thanks so much for any guidance and opinions on this. I greatly appreciate your time. -Scott

Hi Scott,
This is the ideal situation for Lunos E2 ventilation fans. I spoke with the folks behind this project: Converted Shipping Containers Provide Safety During the Pandemic, and they raved about their effectiveness. They are really well-suited for small, tight envelopes like yours.
Thank you so much for your information! I will check it out ASAP.
If you are in not too cold of a climate, the Panasonic WhisperComfort ERV is a good option. I've used these and work reasonably well. For the money they are a good deal, although not the best efficiency.
Some people have had issues with too high of a humidity wrecking the electronics, so I would keep it out of the shower area.
The nice part about the unit is that you can get a dual hood for it so you only have to punch one hole in the wall.
The unit will also work with standard line voltage wall controls, for example I use an occupancy sensor in the bathroom for triggering boost mode.
Hi Akos, thank you so much for your advice. I am in Roanoke VA USDA zone 7 and it got down to 0 degrees so far this winter. I’ll be looking into your recommendations so I greatly appreciate your direction. There are so many options and being a non traditional build, I am not sure where to look.
