The cross flow heat exchanger (in video) is relatively inefficient compared to a counter flow heat exchanger which can achieve 95% i.e. 0 C outside 20 C inside, stale air leaves at 1 C in coming air 19 C. The SOLCER house built in 2015 by Cardiff University has heat pump coils in these last 2 air flows and a third coil in the hot water cylinder.

Actually there are 2 fans. One is on the supply air and other is on the exhaust air.
The device even has heat recovery. You also save a lot of money.
