Geothermal heating or air to air heat pump?

Our housing company has bought this geothermal heating system. Today was the renovation day to plug it on. 

We had no heating on during the day - or would have not have without the air to air heat pump! 

We are the only one in pur housing co having the air heating system, and it was a cold day outside today. I bet all the others had it cool in the evening! 

Love the air to air heat pump!
