Gas rating!!!!

[lame plumber]

Did you get the indexs from two minutes apart?
on a metric meter?

if so just do the amount passed in two minutes times 30 to get m3/hr

0.093 x 30 = 2.79 m3/hr

Then times by 10.775 to get kw gross

2.79 x 10.775 = 30.06 kw gross

then divide by 1.11 to get kw nett

30.06 divide by 1.11 = 27.08 kw nett

took me less writing to say most of that 🙂 but all I got was ????????? 🙂

Cheers everyone, I have sorted it now. Alot of the time when gas rating boilers the gas flow rate in the technical data will be miles out because it will have been checked under different conditions when manufactures test it BUT saying that, the answer you get when gas rating is in KW and will be within the tolerances. I hope everyone knows what I mean, this came from the guy who came to inspect my work. It was confusing the sh*t out of me and I thought I wasn't getting correct gas rates from most of the boilers I had put in. I thought I had under sized pipe work or something. Thanks anyway for all the help
