Thanks guys. A rare find it is, I've never seen heatpumps at such an auction before. It really helped that I'll need the smallest unit, others went for about three times the price.
Dimensions. Outside is going to be 88m2 for the lower floor and 152m2 for the upper flower (upside down living). The garage will be around 40m2.
If all goes well the unit will be picked up tomorrow and I should soon be able to have a look at it. For the moment mostly interested in the pumps used for the ground heat exchanger and the one for the underfloor heating. The characteristics of these pumps are the details I lacked to go and design both these circuits (with all the info in this thread I should be able to do this!) Then I can hopefully score the required parts in some auctions as well.
