New wood stove rusting after being installed - thoughts please?

You do realise heat accelerates oxidisation, right?

 

I genuinely feel instruction manuals are dumbed down for certain customers…..

S'why exhausts rot out before the rest of a vehicle.

No I didn't, but I do now.  Thanks!

The inside of my stove is rusty. Rain comes down my flue of the wind blows from the wrong direction and drips onto the firebox. I have a cowl on the chimney pot too.

Exhausts rot because for every gallon of fuel you burn you produce a couple of pints of water. It's the hydro bit in hydrocarbon, it means water 👍 Have you polished inside that stove it looks surprisingly clean ?

Keep your vents open when the stove isn't in use and it should dry.  I keep meaning to squirt a bit of wd40 around the inside of mine when I'm done burning in spring.... But never remember.

It's because the steam condenses and settles in the exhaust before it gets hot enough to pass out as a gas, wood at 20% moisture produces about 1.5litres for every kilo burned

1.5kg of water from 1kg of wood?

I think he said 1.5 liters of water from 1kg of wood . Seems a lot whatever .

It depends on the bits of wood to some extent and I made a mistake as I assume fresh wood instead of 20%mc wwb

 

We can say wood is carbon, hydrogen and oxygen plus the hydrogen and oxygen  in the 20% moisture.

 

The ratios are approximately 5 carbon, 7 hydrogen and 6 oxygen. that give a molar weight of 5*12+7*1+6*16=163 when that burns it produces 3.5 H20=3.5*(2+16)=63 or 38% of teh dry wood. So with wood at 20%mc wwb thats 0.8kg dry wood and 0.2kg water burning to give 0.51 litres of water. Fresh wood at 50%mc wwb  produces 0.7 litres which is 140% of the weight of dry wood burned.

That's more believable .
