Advice

I want to move a radiator from the kitchen into my new dining room approx 7 metres away. Would it be best to extend the existing 10mm pipes or cut into the main 22mm circuit and run 22mm the required distance then drop down with 10mm. System is 22mm flow and return

Thanks

The only thing is that extending 22mm main circuit and then drop down in 10mm is that its almost guaranteed to work better than extending exising 10mm.
