Ämne: Air to Air heat pump - Confusion on heat pump placement/ duo, single or 2 units

[Pranayrathod]

Dear Friends,

I have recently bought a house with 102 SQM living area divided in two floor plan. It is located in Finspång, Östergotland.
Attached is the floor plan for the house. Entry to the house is on upper floor with living room kitchen and bathroom. Bedrooms are in sutterängplan. Also I believe my floor plan is not as open as it should be however you guys can judge that from below pictures.

I am basically confuse on the placement of heat pump and Should I buy duo heat pump, two single units or one single unit for heating my house. The house has electric heating. I plan to not use electric heating going forward and looking forward to complete heating solution in air to air heat pump. I have been following this forum and very impressed with all expert people helping each other.

Looking forward to your opinion on what will be the best solution for my house heating solution wise, cost and efficiency wise. Please also recommend heat pump model along with your opinion on best solution. Feel free to write in Swedish/English whatever language suits you.

Thanks in advance.
