hi all just a quck one at the moment i have a mega flow system. what i need to know is all my rads are fed by 10mm pipe is this ok for a combi boiler cheers terry

think it'll be fine. we just had a combi boiler put in a few weeks ago, and the radiator pipes look like 10mm (maybe more)

go for a condensing combi, I fitted a grant vortex absolutely great warm and efficient and economical
