I think systems like this make sense. I'm not yet convinced that they are worth 3k more than a pico and a fan, at least as a retrofit.

- pkulak 4y agoThe beauty of a real ventilation system is the heat exchanger. I’m still waiting for someone to make one that I can run by feeding a tube out my window, but until then, you need to spend a bit of cash on a permanent installation.
- WithinReason 4y agoI was looking for such a minified heat pump as well, no luck.
- Scoundreller 4y agoOr just, a windowshaker A/C unit that has a heat mode. (That’s uglier, but surprisingly difficult to find).
- WithinReason 4y agoExactly, but no luck. Maybe there is a technical reason.
- Scoundreller 4y agoDunno either. Should be no issues in flipping the whole unit around. Controls/weatherproofing would be on the wrong side. Put some nice indoor plants underneath it because they'll now be self-watering.
- rapjr9 4y agoYou might try buying two CPU coolers with fans and connect them together via their heat sinks with the fans pointing in opposite directions. Then build a housing for it to match your window. That should transfer some of the heat/cool from the outgoing air to the incoming air. Put a filter on it to keep bugs and pollen out of the house (including the outgoing fan because you might turn it off sometimes. It needs at least a no-see-um size mesh screen.)
