inspired by a very large boiler

We were at Witherslack Woodlands again today, negotiating delivery of a load of logs. I happened to ask who bought the large bundles of twiggy branches. The answer was, no-one. They were used on site in an enormous boiler to heat water in the biggest cylindrical tank I have ever seen. 'Free' heat for a home and offices. The woodsman opened the door of the boiler. The heat was impressive - and so were the flames!

Our stove is just a toy, by comparison.
