We live in a tiny house with 4 people and two dogs and needed to upsize our ventilation system.  We are selling our Luno e2 and it would be perfect for a tiny house with less people.  It provides ventilation and heat recovery.  We used it for 8 months and it works like new.  I have all the components.  New this system sells for $1078.  We are selling it for $700.  I would really like it to go and help someone else improve the air quality in their tiny house.  

Hi Ben, welcome to permies!

It might be helpful to post roughly where you live, unless you don't mind shipping it further away.

By the way, does it run on AC or DC?

Thanks.  I live in Vermont and am happy to ship to anywhere in North America.  It is easy to package and ship.  If you live in Vermont you can pick it up, if you live else where I will package it, but you would need to pay for shipping.  

The units run on DC and it comes with an AC converter.  If you were electrically inclined you could figure out how to run it only on DC power.  Basically it is two DC fans that alternate bringing in air thru a ceramic core (which holds the heat).  

I have never really thought about heat recovery system or ventilation for a tiny house.  But it makes sense.

Do you have the short or long model?

We have the long model.  Can be put in a thinner wall, but would need to box it out to get the depth.  Thanks for asking.

Thanks for clarifying. I hope you can find a good home for it. Good luck.
