Does that mean with a geothermal heat pump?
At what "level" does it run?
Because heating all year round isn’t exactly cheap? xD
The energy for cooling corresponds more to a small circulation pump. Kind of like in an aquarium. The water comes out of the ground at about 5°C and is only slightly warmed up. You need hot water anyway. Cooling is correspondingly incomparably cheaper compared to heating. And right now, worth every cent if you ask me.
good to know : ) I still have to dream about it for a while, but geothermal heat pump is my favorite. Currently, I feel like described here: Close windows and shade everything, it stays cool for a long time (25° until about 7 pm) and then it starts, the insulating effect is broken, or the bricks are so heated up that the heat comes through. For the rest of the evening/night, the bricks release the stored energy again => 29° in all rooms : (
