Hello community,
We are currently planning the new construction of a KfW55 single-family house with a heat pump and controlled residential ventilation. We know that shading can keep the heat out well, but in extreme weather and maybe with careless children, we don’t want to need weeks to get the heat out of the house again. Therefore, we want to install air conditioning units both on the upper floor and in the southwest-facing living area. All air conditioning lines should run via the suspended ceiling in the guest room to the outdoor unit on the garage. The condensate lines are problematic: For the unit on the upper floor, as well as the one in the ground floor guest room, we can lead the condensate drain before the trap of the washbasin in the WC. For the unit in the ground floor living room, we cannot do this easily; we see the following options:
Actually, I find option 1.3 the most charming, but the air conditioning technician does not guarantee that the water will not back up and drip out of the unit. He naturally favors the classic option 3. What would you do? Where do you see the advantages and disadvantages?
Is the air conditioning fundamentally necessary? God knows! We will find out. Either way, we simply want to find the best technical solution for the condensate drain.
Thanks in advance
Best regards
Dash

For the unit in the ground floor living room, we cannot do this easily; we see the following options:
[*
- Have the developer provide a separate DN35 drain in the floor slab, which is located in the wall between the living room and guest room
[LIST=1]
[*]If connected to the wastewater, we still need an in-wall trap (e.g., dallmer klima siphon)
[*]Connection to rainwater is, to my understanding, not allowed
[*]Provide a small soakaway pit under the terrace: Does something like this also work with our marly/clayey soil? Of course, it is difficult to inspect, how should such a thing be executed?
[*]Provide a condensate pump and also lead the condensate over the ceiling in the guest room to the washbasin in the WC
[*]Lead the condensate hose bluntly through a core drill hole to the outside, meaning slotting through the wall between the living and guest rooms, then down and out
