I would need your collective expertise! I have built a small extension to the house and am now facing a so-called "solve it later problem." I need to run water to the underfloor heating manifold in the extension from the house's basement. How should I do this in the best way?
As mentioned, the house has a basement from which the water should be drawn. The extension is built on an open post foundation, which means it can get quite cold underneath during the winter... Is it okay to lay the pipes in the insulation? Can condensation form on the pipes? Risk of freezing? The floor surface layers are already laid in the extension, but it is still accessible from below. Pex pipes are preferred? How to seal the pipe penetration through the basement wall? ...yes, the questions are many...hoping for just as many answers.
An isolated box under the subfloor boards, you mean?
Is it negative to embed the pipes directly in the floor insulation? I thought the room heat/floor heating system could then help prevent freezing if you place the pipes at the top of the insulation...
I should also mention that the heating system is geothermal if that makes any difference.
Everything is ready except for the insulation which needs to be installed from underneath...floor, tiles, plastic, and joists, etc. are done... so if you crawl under the building, it is an empty shell of joists so to speak...
I was wondering if there might be any risk in encasing the pipes in insulation? Condensation, etc.? I've also heard something about no longer being allowed to route pipes through the floor, but maybe that only applies to bathrooms?
Do you need to insulate the pex pipe that will go through the basement wall in some way?
