I want to fit a crossover to the return next to the boiler. 28mm copper crossovers are seemingly very difficult/expensive to obtain as is a 28mm pipe bender.
Currently flow and return are both 28mm and have a long run (15M ?) before they get to the airing cupboard where the cylinder and MVs are.
The boiler flow/return terminals are 22mm and currently the 28 is reduced about 100mm away.
My question is could I have about the last 500mm in 22mm of the returns instead of the 100mm there is today? The flow would remain at 28mm for its entire length except the last 100mm.
