You’re right, it wasn’t impressive so I double checked. It’s 6414 kWh (3596 kWh in southern Sweden) for heating and hot water production without geothermal, only by air heat reuse. It’s a two story house at 164m2 which is three times as large as an average apartment. My point is the insulation is the cheapest way of lowering heating (and chilling) costs. Also, lots of mining, logging and manufacturing jobs up north.
