Hi I'm new to the site so be gentle. i am in the process of moving my combi boiler to the garage and have a cold water feed and hot water pipe diverted to the garage.There are to radiators in thbed room above and i want to conect the boiler ch via the pipes leadind to the radiators but these are only 15mm.I know some of the system is in 22mm from when i disconnected the old boiler is this going to cause a problem ie 22mm to 15mm and back to 22mm? I will have to take up laminateflooring to rectify.
