Welcome (back) to the forum - I see it's a decade since your last post!

The Nibe F470 is an Exhaust Air Heat Pump. It recovers heat from your ventilation system and returns it to the home. To work efficiently you need a *very* well insulated property, and there have been a lot of horror stories where similar systems have been fitted to unsuitable buildings and have resulted in exhorbitant electricity bills.

Can you give some more details of the house/flat it's installed in? Is it a recent build and do you have a copy of the EPC?

There are several threads on the forum about these going back a decade or more:

Edit to add: There's an article here at the Energy Saving Trust that explains how they work and what sort of property they are suitable for:

And here's a BBC report from 2012 showing what can go wrong if one is fitted to an unsuitable property:
