    I have fitted a very small radiator via the flow and return pipes between the Rayburn and the hot water cylinder but the radiator only gets slightly warm. It is gravity fed. It seems to be getting bypassed, it has been air bled several times. Should I have fitted in line with the flow going through the radiator before going onto the cylinder? The radiator would have to get hot then. Its28mm pipe from Rayburn the radiator is in 15 mm. Any help advice would be great.

    For a gravity ciruit to work the flow has to constantly rise toward the radiator and the return constantly drop away from it, the flow valve should be at the top of the radiator and the return at the bottom opposite end, the pipe must not rise & fall it should rise constantly, it sounds like you have not met the basic requirement of syphonic gravitation!! ;)
