Is the air-to-water heat pump expandable?

Hello,

... I am curious whether I will now receive the technical data, annual performance factor, etc.

Here, the total amount of heat output by the air heat pump (measured by the heat meter) must be put into relation to the electricity consumption. Best regards.

Hello,

thank you for your calculation formula. It is probably not surprising when I say that the lady still has not gotten back to us. :( Well, without proper documents we will not buy such an object in this price range.

Best regards
