boiler efficiency


Given that gas central heating is to be used to reaplace the heat energy use the following data to calculate the volume of gas that must be used to supply the heating requirement.

Boiler Efficiency = 100%
Calorific value of gas = 37 MJ/m3

Been asked to do this, can someone tell me the formula or how to do this. I have an infiltration fabric and steady heat loss figures.

Thanks!
volume of the enclosure is 192 if that helps??

    Phone your local heating merchant – plumb centre or someone like that who can do a heat loss calculation – i don’t have my graph at home otherwise given all the parameters, windows etc it’s easy.
