Hello everyone,
The foundation slab will be poured soon, and so far we have only decided on a quote for plumbing including the basic piping, but not yet for heating (which might be done by the same contractor). We plan to install a brine-to-water heat pump and are now wondering if the plumbing and heating contractor also needs to install conduit pipes in the slab for the geothermal system (no basement). The builder has already noted this and plans to discuss it with the plumbing and heating contractor. I’m just worried something might be forgotten, so I wanted to ask.
In the pink forum, someone wrote, "Simply sealing the pipe (conduit) with quick-setting cement or similar is not a proper floor penetration," but unfortunately they didn’t answer my follow-up question about what the correct procedure is. Does anyone here know how this should be done professionally? I had naively imagined that a conduit would just be laid into the slab or the foundation during the pour.
Thanks for your help

The problem is: the seals are really expensive...
Take a look at house penetrations – there are also options that include brine pipes. I once came across prices over 1000 euros (pressure-water tight) for those.

I would recommend also inquiring with suppliers of multi-service house entries.
I seem to remember having seen a multi-service entry suitable for the pipes of a brine-to-water heat pump as well – although I can’t find it quickly at the moment.
Try searching for "Hauff-Technik" in Hermaringen – they have knowledgeable customer service that also provides advice over the phone.
Best regards,
Dirk

We now have a contractor who claims that he embeds the pipes without using a collar or similar sealing and that there are no issues with this. Our building inspector also doesn’t see a problem with it. A relative who has worked in heating system installation said that they didn’t specially seal the main pipes either.
I’m sure that sealing would be better, but out of curiosity: what kind of damage would result from not sealing?
