I've a pending request on how I get from there to the kwh value I'm used to seeing in Bord Gais (natural gas) bills. The boiler is an Optimax 25 and the spec sheet (outcrop attached) says 25.2kW as the max heating power and a max flow rate for LPG of 1.96kg/hr. So i'm assuming it's a 25Kw boiler but am confused by the kg/h spec.
