Been or this job 7 days. Just filled and fired up 2 x 40cdi greenstar regulars. Gas rated them together - getting 72kW @ max. However only getting 5mb working pressure at either boiler. 21mb at meter. Spoke to Worcester and Gas Safe and they're as baffled as I am (although Gas Safe tech said they'll get back to me). Cannot get my head around the gas rate being so high when wp so far off. Anyone any ideas?

Was black dust. Spoke to two Gas Safe tech helps today and they didn't have a definitive answer re gas rate. Blockage on the P1? So MikeCip's idea with the T's would have shown it right away. So thanks for that.
Gas rated separately 1st. Then together. Don't think the way I communicated the volume of gas used mattered to much in this instance, kW, cubic ft/m. Point was I was surprised that 5mb wp was achieving it. Although looks like this was a false reading (blockage at P1)
Cheers guys.
