Yeah I get what you are saying. And sure, if the installation or usage is suboptimal then you won't get high efficiency. And it's also true that it's much easier to use a heatpump wrongly compared to e.g. gas heating. On the other hand it's also not black magic and the more people install and use it, the less mistakes will be made.
