Hi,
I've recently moved into a house and was surprised to see that some rads are connected with 15mm while others use 10mm, there is even one rad that has one of each. While I'm no stranger to CH systems and appreciate that di8fferent pipe sizes can be used to maintain flow and pressure, I've never come across a mixture like this before.
Its a 2 storey house and the system has 12 rads working off a Ferroli F30 combi boiler. The rads are what I would consider as fairly standard sizes for the type of house and the room size etc..
The system appears to work OK but it seems odd to be supplying reasonably large rads with such small bore pipes and having to step-up to 15mm to make the connections. Maybe some of you more experienced folk can put my mind at rest.
Cheers
