ᐅ Multi-utility supply line – Can the gas connection be used for the air conditioning system?

Dear forum members,
I would like to prepare my house, which is going to be built, for a split air conditioning system. A four-way utility conduit is planned to lead into the utility room. Since we will not be using gas, I am asking if it is allowed to use the last available opening for the air conditioning—either for the smaller refrigerant line or the larger vapor line (I hope I understood the cycle correctly :rolleyes 🙂. According to my calculations, I would only need to leave one additional smaller hole through the basement exterior wall.
Because this is a prefabricated house, the manufacturer is reluctant to compromise the building’s thermal envelope by running empty conduits to the outside if they are meant for condensate drainage (upper and ground floors). Perhaps someone has experience or advice on this? As far as I understand, you can hardly run condensate water through shafts reaching down to the basement, can you? Would it then have to drip into a sink or similar?
Thanks for your input,
Reltaw

And yes: I would connect my fourth supply in the end, but the PREPARATION for it must already be in place. If I haven’t installed an empty conduit and don’t have a trench available for it, I might as well plan a completely separate connection. That wouldn’t be any more complicated.

motorradsilke21 Jul 2021 13:20Can a utility provider prohibit me from installing something in the 4th conduit meiner of my multi-service house entry, as long as it doesn’t interfere with the other utilities? It’s basically just an additional pipe.
However, if you want to be certain or anticipate any issues, just lay a PVC pipe in the foundation slab. That’s how we did it for extra cables (which run in a different direction than the multi-service house entry; otherwise, I would have just routed them through it) and for the heat pump. The drainage pipes also exit there.

And if the diameter for supplying the outdoor area is too tight anyway, then it simply has to be done with a second hole.
And yes, such a supplier has a monopoly. They can decide if and when they deliver. My construction water was denied because the building permit / planning permission is not yet approved, and the telecom company only installs their equipment if the room can be locked.

motorradsilke21 Jul 2021 14:28Yes, of course, the latter is logical. But utility providers in Germany are required to supply you with at least water and electricity, as long as you pay.
Regarding the MSH, I think that idea is completely mistaken. You need two refrigerant lines with insulation and an electrical line. So something has to be installed separately anyway.
The condensate simply drains out of the indoor units. But unlike the lines mentioned above, it doesn’t have to be routed to the outdoor unit. It is sufficient to connect it to the nearest drain. This can also be done under the screed.

It would be interesting to hear from people using timber frame construction, which we are, how they manage to remove the condensate from the indoor units.
