Multi fuel stoves..

[nightrider1470]

I have a multi fuel one that can do coal and wood.

Is all coal the same or does certain types last longer?

I seem to be putting new coal on every 30 mins or so then throwing the odd log on.

Looking for some advice

Have just bought a load of strong paper takeaway bags and plan to fill with coal and tie with string so I can just throw bags in rather than having to carefully shuvle

You are meant to close all the grill gaps when burning coal and have them all open when burning logs.

AHhH! Didn't know this!
