How we do it
Some alternate direction every minute or so, storing heat in a ceramic core; others run supply and extract side by side through a small exchanger. Either way, the room gets fresh air without the heat loss of an open window. They are popular in flats, in north-facing bedrooms where mould keeps coming back, and in rooms with no route for ducting.
