Hi chaps, im going to be swapping my g plan? Heating system soon for combi, im not sure about how the main f&r come back? Does it come back via a open rad or does the main 22 f&r loop back on its self. Hope my pic helps cheers guys. Attachment Deleted |

hi endfeed, make the last rad you're turn round point, if you join the 22mm pipes up with do rad, it will 'short cut' home, because you've given it a route of no resistance,  Attachment Deleted |

Will the last rad that you've drawn as the return pipe also have the same on the ground floor?

it does't matter which order the rads go in, as long as each rad gets linked into the flow and return , One thing I forgot to say is..
the pipes come off the boiler in 22mm pipe, the rads need 15mm pipe or 10mm pipe depending on the size of the rad,
10mm will deliver 10,000 btu's thats a big rad so unless you're in a mansion 10mm will be big enough for every rad,
