Huge gas rate

[stani]

has anybody tried working out the gas rate for a natural gas 12kw but mistakenly using the figures for LPG?

I suspect it has been rated incorrectly , band A boilers do have to be gas rated or you will not know how much gas it is consuming plus an FGA

Just done the maths on this one

You've applied the calculation for a metric meter to an imperial

And if you want the maths I'll be able to talk you through it
