That 12x10x8 stack sounds about right.I am multi fuel and use coal as well.About half a ton a year ( we hold a ton at any time,so that's two burning seasons).our stoves are our primary heat source,so I find that quite reasonable.There is a steady stream of wood coming in from various sources,and that ensures Chez Jansman is not overwhelmed. It is processed and stacked within a day of arrival.I never fetch it - it always comes to me in the form of someone else's waste ( two landscapers and three builders) as fetching it means too much energy expenditure. Mine! Again,we hold a couple of years worth,as we have a very,very large garden.
The problem with generating your own power or heat is that it makes you realise just HOW MUCH energy is consumed.When you flick a switch for gas or electric the sheer volume is hidden.One reason why using a generator for anything but short term /low power drain is unviable.
Building a stock is great,but the volume and consumption rate means you are forever keeping an eye on it,as you are literally burning through it! One reason why free or very cheap wood is best if you are able to acquire it.
Of course,you can slow usage by using more efficient stove(s), better insulation (which means you can slow the burn rate once you are warmed up) and the type of wood you burn. Hardwood is best.
Sometimes I wonder if its all worth the cutting and stacking,pratting about with chainsaws ,and mauls,and... You know. But it does give us independence, which is great.And on a rat hole day like today thgeres no better heat.
In three words I can sum up everything I have learned about life: It goes on.
