Hello everyone,
since our construction will begin soon (earthworks), I am now wondering about the best way to install the necessary lines for the heat pump (connection from the indoor unit to the outside). I’ve heard that some people simply use a wastewater pipe. I find that a bit strange for a newly built house from 2022.
What have you used here? There are building entry systems available for purchase. According to the heating engineer, this doesn’t work so well with the refrigerant pipes (copper). However, I’m curious about the difference compared to a 125mm (5 inch) wastewater pipe.
Thanks in advance.
Best regards

I had originally planned with the builder to run a KG pipe through the foundation slab for the heat pump pipes. But my heating engineer preferred to run them through the wall because the pipes are thick and rigid. Now I have both. So far, no mole has appeared in the utility room...Same here, they said the foundation was in the way, so it had to go through the wall.
