all over germany and austria I saw wood stacks of 1 meter long wood. I couldn't figure out what they were burning it in (knowing a bit about the euro gassifiers) but found out that they cut and split in 1M lengths, for easy stacking, handling etc, then buck it into 1/2m (19") or 1/3 M (13") lengths for inside storage and burning.I do understand that the 13" wood will dry much faster due to the greater endgrain exposure, however...... Has anyone ever tried stacking 12-13" wood? If it doesn't fall over your better than me. I usually have about 1/4 cord of ends, uglies, etc that are in that length range and they are hard to stack to any height.
The stove came with a faulty thermostat, it is 10 degrees out so I have to set it at the maximum 70C to get a return temperature of 60C. It is probably part of the problem, another ten degrees might help but part of the problem is that the flames don't reach the bottom of the flue ways as they would in a normal stove.
Passion do you still have access to the Walltherm units?Soem pictures of the safety cooling loop and PAW pump group.
