Is there any reason why I cannot put a copper pipe to the outside of the
house (connected by an isolator) to act as a CH drain. I basically want a
simple drain option to my CH and this would make an easy drain solution that
would not need hosepipes etc for any further CH drainage.
Any ideas why not?
I've had this capability on my heating system for the last 20 years - very
If I were doing it again, I'd consider plastic pipe as it has a lower thermal
conductivity and so will lose less heat. Possibly not a major consideration
No reason whatever. I did this when installing CH in my previous house over
30 years ago. The house had suspended wooden floors - and the pipes for the
downstairs rads ran under the floor. It was thus simple to tee off a drain
pipe, and take it out through an air brick. I put a stop-tap just inside,
accessible via a small hinged trap in one of the floorboards.
Put a stop cock on it. If it is hanging over a gully then the pipe can
remain open and facing down. If not over a gully, then have a cheap drain
off cock fitted and leave it open permanently, then you can attach a hose.
When these are opened after being tightened for a number of years, they tend
to leak, so having it permanently opened prevents this occurring.
