A long-term solution is to install a ventilator with a heat exchanger. Outgoing air on one side of a thin metal plate warms up incoming air on the other side. This covers about 50% of the temperature difference for free.
- lucb1e 7y agoI didn't know that was a thing. It looks like most are 250 euros or even double that. It's a fan with a metal plate right?! Or is there some built in fridge-like construction to exchange the heat? There is also one result for 50 euros (1.7/5 star average) but alongside the 250-500 euro results that doesn't seem like it'll be the same thing.
