More news from Wojciech

This might be the first natural draft coal stove to meet the EU level 5 performance level.  The PM seems high but we noticed they changed the secondary air entrance.  It appears they did not understand how it works, exactly (it is not like other stoves.

Anyway, this shows that the developing world can provide better product development “in the field ” than the Western countries.  There was a EN303-5 compliant coal fired water boiler described at the Warsaw CCAC meeting - $2900 with computer controlled with sensors and fans.
