Thermal value of wood?

n · Thermal value of wood?

My OH was offered a cut down ash tree last week. We will take some of it, but we can't transport huge amounts, and he's an axeman (in the nicest possible sense) not a chainsaw man.
I was wondering if there was anywhere which lists the relative values in heat terms of different kinds of wood. There's one in the Tightwad Gazette, but I don't know how accurate it is.
We don't plan to burn it until Winter 2008/9, the people who offered it were rather astonished when OH said he had a rotating wood store system.
We have some unknown logs, and some Scot's Pine, which I know is more sappy and won't generate as much heat. And we have whisky cask stves which are oak and burn well and hot. I think as is somewhere in the middle, but we may be offered other wood, and I just wondered what gave the most heat per log?

As a general rule, softwoods will contain less energy per weight, I think. Ash is a pretty good one for burning.

I believe ash is one of the few woods which burn well green.

Gosh, I didn't know that. It is okay for the stovepipe? It won't gum it up will it?

nanny-now and forever

i think you can burn it straight away

i am eyeing up the overhanging boughs of the one at the side of the house and keep suggesting that mr nanny gets up the ladder to trim the tree whereupon i will collar the bits for kindling

and it will improve the view no end............

Here's an old poem about it. Scroll down the page to see what it says about the different wood types.

Ash has a very low water content, and is considered best of all for burning without seasoning. If offered it, my advice is take all you can and get it stashed. It splits easily as kindling, and bigger logs burn well, giving tremendous heat. You won't suffer tarring of the stovepipe in the way you would with resinous trees like pine, either. Can't go wrong, just say yes.
