nickw Posted June 3, 2021 Share Posted June 3, 2021 Foundations going in now and have planned for ASHP pipes thru them , the Ashp and plant room is approx 12 metres away , silly question but braided flex hose to Ashp what pipe are they then joined to?, Ashp is 3 metres away from the building wall and then 9m in the slab to come into the plant room.

IanR Posted June 3, 2021 Share Posted June 3, 2021 I used a pre-insulated twin pipe: Rehau RVT DUO 32 + 32/150 If you need to bring it up vertically through a slab, it needs quite a deep trench due to the minimum bend radii. Link to comment Share on other sites More sharing options...
