my hot water pipes are micro bore,heating system is 15mm piping, can you add a 15mm pipe to a micro bore pipe on the hot water system ? I have never seen hot water pipes in micro bore only rad pipes
If you mean you want to convert microbore 10mm to 15mm conventional then you can - you can get a solder or a compression joint to do this, and its actually called a reducer. I've never seen domestic 10mm either!
