Hi,
Am adding 3 new radiators in an extension to an existing sealed system (combi boiler) that uses 10mm pipe at the radiators.
I have traced the existing rads 10mm pipe back to the 15mm flow and return pipes and my question is this.
Am I best teeing off the 15mm flow and return pipes with 10mm pipe to the rads individually (about a 6 meter run) or teeing off with 15mm pipe and then reducing to 10mm closer to the rads, effectively extending the 15mm flow and return?
Cheers
