I am getting to the point where I am about to lay a floor screed in a new extension - hooray!
My cold mains feed comes in under where the sink will be on one side, the water softener and cylinder is on the other and the boiler is in between the two - boo! So I need to lay the following at least:-
15mm cold mains feed to water softener
15mm softened cold feed to kitchen sink (there will be a mains feed at sink too)
15mm hot feed to kitchen sink (possibly two to run a loop)
Flow from boiler to cylinder (connection is 1"BSP)
Return from boiler to cylinder (connection is 1"BSP)
Underfloor heating 'pack' possibly 2 zones
The distance is about 7m directly across the floor, longer (nearly double) if I go around the edges. Can I run these pipes in the floor screed? i.e am I allowed to run water to the sink in the floor screed? What would be the best way to run these, to keep them insulated and seperate? What would be the best pipe to use? I know if I use copper I need to protect the pipe from attack from the concrete, so was thinking about using Hep2o. What size pipe do I need to connect to 1" BSP as that seems to equate to 25mm which doesn't seem to be a popular size? Where can I find the regs on laying pipes in the floor etc. so I can try and fact myself up?
Sorry for a load of questions, but the more I have looked into it, the more confused I have got...!
