hello
i'm after a few opinions really to get some idea which way to approch a job.
Im estimating for a full heating system from scratch. The customer has warm air heating but its just been condemned so no rads anywhere. They are happy to have rads but done want any pipework on show so the idea is to chase 10mm plastic into the the solid walls and come out behind the rad. So no joints it the wall and no precise measurments for rad tails. I'll run silver tape behind so they can be identified with a detector.
problem 1 ; plasterer cant guaranty it wont crack which i can see his point so will some sort of pipe rap or tubing solve that. i was thinking about the sort of pipe conduit you use for underfloor heating between rooms.
Problem 2 : they live right next to a field to natrually they get mice so the loft has to be copper. the idea is to connect a 10 to 15 speedfit elbow then staight into copper for everything in the loft.
Problem 3 : They want either a storage combi (probably viessman 222-f) or boiler and unvented cylinder (viessman again.) The incoming main is 15mm but not bad flow or pressure plus its right near where i need it to be. Iv only ever ran from 20 or 25mm incoming mains so im curious if anyone has been sucessful with 15mm? theres a big jacuzzi bath to fill so thats my concern plus they like a good shower.
Feedback would go down a treat.
thanks very much
